How’s yours? Gears, features, kickdown, smoothness, etc. I have a 4 speed slushbox, as you’d expect. It shifts surprisingly quick, and the torque converter stall is high since this V8 isn’t very large and the car weighs 4300 LBS with me in it. The kickdown is strange at highway speeds. It wants to throw you into 2nd no matter how few RPMs you’ll have left. For that reason you have to do partial throttle so it’ll give you third, and then lay into it after 80 MPH where 2nd tops out. A 5th gear would be nice, it’d feel so much quicker around town and the highway kickdown would be much better.

The G6 has 4speed slushbox that doesn’t seem to want to start in 1st unless you stand on the brake. I figure it is for fuel economy, by it can increase the pucker factor a bit if you are trying to squeeze into an opening in traffic.

I no longer own the car, but I loved my ’96 Thunderbird’s 4R70W (AFTER the rebuild, that is). I put a J-Mod shift kit in it, along with a (Mustang, I think) torque converter. The shifts were firm but not harsh, and easy to anticipate.
The (supposedly rebuilt) 4L60E in my ’95 Sierra is a different story, though. It shifts harder than necessary at times, and after a year of ownership, I’m still figuring out its shifting habits.

I’ve got an A4 with the ZF 8-speed that is in pretty much everything these days. It’s awesome. Smooth when throttle inputs are light. Aggressive and quick when in sport mode. Even the manual shift mode is decent. It holds revs and doesn’t automatically shift if you get too close to redline. It’s doesn’t struggle to hunt for the right gear. I really enjoy it.
Previous car had a 6MT and I find I enjoy driving the auto just as much

I like the 6F55 in the Taurus. No searching for gears on hilly terrain (assuming this has to do with the flat torque curve of the engine) and in sport mode it allows lightning fast upshifts and downshifs, it will even downshift for you around corners to maintain best speed. the one complaint is on the high end of the RPM is that it will still shift for you regardless.
The 200-4r in the Monte isnt bad in straight line, but on autocross it shows its weakness, its a semi manual valvebody, so up-shifts and starting gear are completely controlled by me. however, downshifts can still happen in 2nd gear, which isn’t great on an autocross course which leads to it feeling like it is slipping, it isn’t, it’s just thinking it wants to downshift on heavy throttle input. Oh and when it gets hot under pressure it will leak around the dipstick tube... I want a TKO600 or a T-56 so badly.

I think the LX450 has the A343F if I’m not mistaken. It’s a stupidly long 4-speed thing. I’d really appreciate a 5th gear not for a higher ratio but for a wider one. Just did a drain and fill with Mobil1 synth ATF. It shifts well but not 100% smoothly and in low range the shift from 1st to 2nd is really hard. Not sure why, but it’s been that way in every land cruiser I’ve ridden in with this transmission.

I’ve got a 2015 GS350 AWD, with the 6 speed auto (IIRC the RWD cars got the 8 speed that year). It’s pretty meh compared to the competition - and that’s being kind. Shifts aren’t particularly quick, and the thing has NO IDEA what to do when you give it about 2/3 throttle. Of course, it rushes to get into top gear, because Toyota (sport mode fixes that). Shifts are smooth, however.
On the other side, my wife has an X3 with the ZF 8 speed, and it’s brilliant - quick, smooth shifts and does a far better job of choosing the right gear when you boot it. I’m not a fan of the electronic gear selector, but that’s mainly because I don’t drive it that often.
Also have a 2005 Pathfinder with an autobox, and it works, I guess? Which is pretty good for a 167k mile Pathfinder.

I have a 4 speed auto with one overdrive. It will sometimes kick down when you just want a little. Mine will do 70 in 2nd but I never do that because that happens around 5300 rpm and redline is 5500. I learned this when I was about to get rear ended because I was stuck behind a school bus doing 30 in a 70mph zone so full throttle it was. But overall really smooth. Shifts are fast enough in normal mode, but with ect power on it’s pretty quick.

There are two stages to these 4 speeds when you step on the gas - one is unlocking the torque converter, which feels like shift, the other is actually shifting gears. That happens at different points on the way down with the gas pedal, and that might be why it feels so odd kicking down.
Try manually changing to 3 and see if you notice the shift and lockup as two separate things. It will be more obvious if it’s not dropping a gear at the same time.

I actually liked the paddle shifted 6 speed auto in the ‘14 Camaro that I drove. It let me bang off the revlimiter and it shifted when I clicked the paddles. I didn’t particularly like that I couldnt make it up mild inclines in 6th gear at 70mph without downshifting but that is more of a fault of the car being a 4600 pound behemoth with a tall overdrive. Anyways, that was the only automatic I have driven that I didn’t hate. Paddle shifters are 100% required if I am to have any fun though. Makes it feel kinda like a video game but thats okay, i like video games.

My new F150 has a 6R80 in it. I’m happy with the spacing of the six gears, and the shift quality is fine. My understanding is that it is a derivative of a ZF 6 speed design that Ford builds and licences from ZF. It had some shift patterns I didn’t like when I picked up the truck, but 1000 miles later the computer has done a descent job at learning what I want it to do. When I first got the truck, it seemed to often start from a start in second gear at light throttle. It has since learned that I don’t like that and now seems to always start in first gear from a stop. I also thought it was a bit too quick to kick down from 6th to 5th, especially in urban interstate lane change/acceleration situations. There it seems to have learned that I would prefer it to hold gear and let the turbos spool up unless I really give it the beans.
The tow/haul mode will be useful, especially the emphasis on engine braking it provides. The sport mode seems to only hold gears longer and exaggerate throttle response to pedal input. I don’t see much use for sport mode. The manual mode will be handy in certain towing situations like mountain passes where I want to fully command what gear the truck is in.
Overall, I’m a happy camper with it after two weeks and 1000 miles on the new truck. The ability to display the precise trans fluid temperature via the dash display is something I really like.

I have an 8-speed in the truck (845RE, beefed-up ZF 8HP45). I love having eight gears. It’s smooth, responsive and almost psychic. When I hit the pedal it seemingly knows just how much I’m going to press and shifts accordingly - minimal hunting and minimal lag. 75mph cruising at ~1600 RPM in a 5,000 lb truck is sweet.

I can’t really complain. Picked it up for something like $700 with 142,000km (88,000 mi) on it, did a timing belt service, tossed some new front control arms on it, new battery, and it has been completely reliable for the 6 months or so that we’ve been driving it. I do need to replace the tie rod ends in the near future though.
Heated leather seats front and rear, kickass Bose sound system with 12 disc changer (and cassette!!), and rear wheel drive make it a decent place to be. If the car had a manual transmission I’d probably love it to pieces, but with only 200 or so horsepower on tap the auto makes it feel a bit lethargic. Needs more on power oversteer for me, but it was meant to be the wifes car anyway.
Coincidentally, the midsize Catera has a 3.0l v6 with 200 hp while the full size e38 has a 4.4l v8 pushing 280-something hp. The e38 feels (and is) much faster, yet both have roughly the same average fuel economy. With fuel at approximately $5/gal here in Canada, that bugs me. Still though, I can buy a lot of gas with the money saved on not having a car payment.

The ZF box is soo good for an auto - really. I’ve only driven it in various BMW’s, so tuning will vary a bit between manufacturers, but it gets good reviews wherever it goes (unlike their 9 speed box).
That’s pretty helpful - it means more plentiful *and* cheaper replacement parts when needed. On one condition - that you don’t also share the integrated radiator/trans cooler that the Pathfinder/Xterra/Frontier used in that generation. That item has sent many trucks to the boneyard—

Mine is 4spd with overdrive. It has the weird Chrysler “autostick” thing where it’s kind of like a semi-auto control. But not completely. It more tells it what the highest gear it can use at that time is. So say I set it to 3rd, it’ll still use 1st and 2nd. Also you shift by moving the stick left and right, which just feels awkward.
Left to its own it works pretty well. Never feels like it’s searching for gears. And is the first automatic I remember using that I don’t ever feel like I’m fighting with it to get the gear I want.
Smoothness is pretty good. Occasionally I can feel a small jolt as it locks and unlocks. But the shift speeds are pretty good while still being quite comfy.
Also learned while doing a speed sensor replacement, that this same transmission was used by Porsche for some of the PDK stuff in the early 00's! Which I could easily see being the case with a different transmission tune.

Lets start with my wife’s 2013 Edge - upshifts are generally smooth, but downshifts are often slow and clunky. The transmission is usually in the right gear, though, so it’s not bad. Maybe 7/10 overall.
I’m not sure if my Focus’ trans counts since it’s a double clutch automanual, but I’m going to talk about it anyway. When it was new, it drove like a 15 year old learning how to drive a stick - slipping clutches, slow upshifts, slower and more violent downshifts, and it was usually in the wrong gear. Sport mode helped, but it still wasn’t great. After 2 and a half years (!), Ford issued new software they helped a lot. Upshifts are much smoother if a little slow, but downshifts are much better. It’s still usually a gear higher than it should be, but its usually smart enough to downshift before it has to double downshift, which is slow on any double clutch trans. VW needs to take a shot at programming this thing. The DSG in my friend’s GLI was lightyears better. When new - 3/10. Now - 6.5/10.
The best auto trans I’ve ever driven was the 5 speed auto in my parent’s/sister’s 2007 Honda Accord. That thing seemed telepathic, downshifting as soon as the engine had any kind of load from a hill on it and upshifting quickly and smoothly. It also helped that the K24 it was bolted to made good power, decent torque, and loved to rev. The only thing the trans did poorly was the 1-2 shift when the car was cold. That was slow, but the ‘97 Accord I learned to drive on and the ‘02 Accord we had before the ‘07 did the same thing. 9/10

I’ve got a 5 speed auto in my Legacy. I’m not a huge fan. My biggest problem is with its behavior during slower speeds when I’m using light throttle input. It’s like it can’t decide what gear it should be in, and keeps switching between I think 3rd and 4th. It shudders fairly frequently when it does that, which is disconcerting. It also gives quite a jolt when you let off the throttle to turn a corner, and then get back on it. Not always, but more often than any other auto I’ve driven. Sport mode fixes a lot of that, but holds 1st longer than I’d like. I usually wind up starting in D, moving over to Sport after 1st, and then back to D after I’ve come to a stop. I find myself wanting a manual sometimes, since I’m having to pay basically as much attention to the transmission as I would when driving manual. That said, it’s lovely on the highway, 5th is a nice long gear. And sport mode is quite good when it gets hilly/twisty

Yup, the 5hp30 was only offered in the 1995 740 with the M60. When they went m62 in 1996 they switched to the 5hp24. (I believe all of the 750's still got the 5hp30 though)
They’re basically the same transmission, but the 5hp30 is actually able to handle more power and suffers far fewer internal failues than the 5hp24.
The 5hp30 is stout but is often effected by an easily remedied valve body issue, where the 5hp24 is known for A drum failures, which I can attest to. Still a great transmission though.

I’m... not entirely sure actually. Im pretty the 5th gear is just its overdrive. When I use the “autostick” feature it gives me 1-4, and then D (since that’s just telling it to use any gear). When towing the manual says to keep it in 4th as well, since towing in OD is normally bad.
Honestly I’m not sure why we differentiate autos as “x speed with overdrive”. Since lets be honest, that overdrive is just another gear that it’s programmed to use just for cruising due to its steep ratio. That’s fundamentally no different than how I use the 5th gear in my manual trans car.

Jeep: AW4; Just like yours, anywhere on the highway if you even think about touching the gas it will downshift. Kinda annoying since it has a Flowmaster 40 on it that is obnoxiously loud. Still, it’s a great transmission, shifts quickly, very smooth.
Silverado: 6L80; I don’t like the programming. It tries to ‘learn’ how you drive and adjust accordingly. It’s gotten better over time, but juts a little when you shift into V4 mode then tap the gas and it downshifts and switches to V8 at the same time. Still very smooth 95% of the time, but it’s a little slower than the Jeep’s transmission, and the inconsistency is annoying. A lot of owners of this gen buy programmers that remove the learning and make it shift a little firmer. May try that in the future.

I’m a bit of an opponomaly, preferring autos to manuals in cars. I’m not a good enough driver to need more than an auto can do or to think I can shift better than one. I need to concentrate more on the road ahead. In traffic manuals just plain suck, and that’s most of what I drive.
My E55 had the old, tried and true 722.6 five speed that’s been seeing since the mid 90's and has been used in everything from SL65's to Chrysler crap top Porsches.
It’s an excellent transmission. Not always the most intuitive or quickest shifting, but I’m not faulting it for that, for its time it was hard to beat. Service them regularly and they will last longer than most of the cars they were installed in.
If I want to choose gears myself I’ll jump on the bike. It’s way faster than 99% of cars on the road anyways.

Really though, why does this transmission have so many names?! Are there actually differences in them? When I was doing some repairs I used the video instructions from a Porsche speed shop because even as they said, it was the same thing.

I really do like them, I’ve driven a 95 540 quite a bit that had a 5HP30. I didn’t know the 24 was a bit weaker, that’s strange that they’d make that choice

4-speed slushy here too. Completely chokes the engine by not allowing it to rev above around 4500. Which is good for reliability, fuel economy and the engine’s power peaks around there anyway, but not great for fun. Otherwise it’s smooth enough. If you really lay into it it’ll do its best pathetic impression of a race car by slam shifting your spine straight out of your back.

I do a lot of traffic too, hence the boat. But I do finding myself missing a manual transmission. Not for the hardcore spirited driving, but for blipping a downshift into second or third and hammering it for a second or two. It’s just oh so satisfying.

The 6L80 in my Silverado is pretty good now that it “learned” my driving style. Sometimes kickdown is a bit slow but otherwise is does what it should pretty well. It has a manual mode with buttons on the column shift that holds gears, but it’s slow to respond generally. When it’s not up to operating temp it has a tendency to clunk from reverse to drive and from first to second but it stops after a couple minutes.

I’ve never considered the impact of cylinder deactivation on a transmission. Sounds like it has to adjust some parameters in a way it doesn’t like to compensate.

I have a similar powerband, significantly more torque at 4K RPM than horsepower at the top end, so the wild downshifts are totally pointless. I really wish it’d let me floor it on the highway at 70 and just stay in 3rd.

Manual shifting would be nice, even just the + and - section would be cool for back roads. I can’t abide by changing between 1st and 2nd with the shifter, it sets of my mechanical sympathy too hard.

Oh wow yeah I bet the Outback was horrible, I learned to drive on a 2001 but it had a 5 speed because my dad is old school and ordered everything with 3 pedals until his knees went bad. Such a good car though regardless of the transmission.

I have a good clunk when shifting into reverse, but I think it’s just slop in the 18 year old drivetrain and I hold the brake down hard to minimize it.

I drove in the car of a coworker who had one of those weird Ford double clutches!! The new driver with a stick analogy is 100% accurate, I can’t believe they released the car like that. It felt like a very broken transmission. This woman was not a car person and she was too lazy to take it in for a recall...

it just has this thumb button with a +/_ on it and it’s slow to respond to input. really it’s not fun at all. plus the Malibu is slow and heavy and under powered and has a suspension that’s total garbage.. it’s an awful car devoid of joy or redeeming quality of any kind. I swear this ended up in the car purely because every other car in the segment had it already. because it’s too awful to make any sense or be worth playing with.

Best auto trans ever was in my 1992 Volvo 740 sedan. It was a 4-speed that could be driven like a clutchless manual. Both 1st and 2nd were selectable, and the O/D Off button disabled 4th. I’m not sure I ever just left that car in D. With 320k on the clock it was solid as anything I’ve ever driven.

I think St Jimmy’s 4L60E is slipping. But I’m not positive of it’s actually the trans having issues, or the engine. It revs up and cuts back as if it was slip, grabbing, slip, grabbing, but I’m not sure if the loss in accel is due to the trans slipping or if the engine is cutting out and the tach just isn’t keeping up. The fluid was burnt and super low on the dipstick when I bought it... for $250.
I’ve only got experience with two 4l60E’s and both of them had problems. The other one cracked the sun gear, as they do. They both shift clunky and the gears have annoying ratios, second gear being way taller than it needs to be, meaning there’s almost no engine braking unless you drop to 1st which is crazy overrevving.
On the other hand, my MJ’s AW4 is solid. Sure it could shift a bit quicker, and it’s annoying I can’t select 1st (1-2 is the same position on the shifter and it always seems to grab 1st before I’m ready when engine braking) but I blew a seal on one of the cooler lines on it, and drove to the point it started slipping, topped up, slip, top, slip, for quite a while, with 300,000 miles on it. Fixed the seal, topped it back up, and she’s good as new.

My guess is that each company will apply it’s own nomenclature to products they borrow from others so that it fits their culture and parts software and catalog layout stuff. Maybe even a little bit of “we can’t have everyone knowing were using so and so’s parts!”
But as far as the NAG name, all that stands for is New Automatic Gearbox. Which is an acronym Mercedes uses, but it’s sort of like just calling an orca a whale instead of an orca. NAG applies to more transmissions than just the 722.6; it’s actually more frequently applied to the 722.9 7-speed in Mercedes shops. Genus vs. Species.
There are in fact significant differences depending on year and application. They are denoted by digits beyond the 6, as in 722.6xxxxxxx. But that’s way more than must people ever need to know and probably no one has any of those further digits memorized. But they do make a difference. Some of the biggest differences are number of discs per clutch pack and number of bolts for the output flange (3 or 4).

Yeah, more like compounding factors. The slight nudge when double the cylinders suddenly start running, combined with the downshift. It’s less the transmission shifting harder and more the more noticeable feeling/driveline shock from the combination of factors. It’s not perfect, but I can’t complain. I still don’t notice some of the shifts under light throttle. It’s very smooth.

My A4 also has the ZF 8 speed auto. It’s the best auto trans I’ve ever driven. I spend about 60% of my time with it in manual mode and shifting with the paddles.
Sometimes I want to go back to a manual sometimes I don’t. My current proposed compromise is to buy an old sports car for when I want a clutch. :-)

I have a 2010 Honda Fit Sport (5AT). First and second are pretty short. There’s quite a gulf between second and third. Third through fifth seem taller. In fifth gear at 78 mph, the engine speed is roughly 2800 rpm, slightly higher than I’d like it to be. Nevertheless, I can attain about 36-37 mpg on long Interstate drives, which isn’t bad. At freeway speeds, the transmission will kick down to fourth without much hesitation and will drop down to third if really needed.
The worst thing I can say about the transmission is that it feels ‘slushy’. I can totally see where the pejorative ‘slushbox’ comes from. Shifts feel slurred and indecisive, as opposed to the firmer, more direct engagement of a manual, single-clutch automated manual, or dual-clutch transmission. The transmission hunts around quite a bit. If I try to accelerate up a gentle grade at a constant rate with partial throttle, the shift pattern always goes 1-2-3-2-3-4-3-4-5. It’s somewhat annoying, but whatever. Convenience has its price. The paddle shifters work in ‘D’ to temporarily move up or down a gear; in ‘S’, the transmission holds the gear until the driver shifts. I generally leave the shifter in D and use the left paddle for an occasional downshift. I just have to be careful not to downshift from third to second too soon because of the aforementioned gulf between those two gears. There’s a display in the gauge cluster that shows the current gear after the driver pulls one of the paddles, but it goes blank again once the transmission goes back to its own business.

I generally avoid autos, but it’s a nice feature if your car is so huge you have to concentrate not to hit anything.
Anyway, 2 speed auto, it shifts in second at around 30km/h (I guess, the speedo is broken, and there is no tach). Kickdown does nothing. With a little help from the torque converter, it slaughters the engines few horses and pushes the car forward, slowly.
It sure is no argument for me to get anything auto. Then again, it’s 57 years old.

The AOD in my Cougar has had extensive modifications. Upgraded bands, servos, input shaft, torque converter, a gigantic transmission cooler, and some other odds & ends. It’s now rather aggressive and with a little tweaking on the line pressure, I can turn it into an animal on the razor’s edge. I have it at about 7/10ths of it’s full kill capability normally. I’ve yet to see another AOD that shifts as good as this one.
The 5r55S in my Mustang has had the shift firmness increased and the WOT shifts occur at 6700 RPM. I’ve upgraded the transmission cooler and have installed a hardened input shaft. The 1-2 shift @ WOT is violent with the 2-3 shift very close to that as well at the dragstrip. In routine driving it behaves quite normally.
The 2008 Dodge Nitro R/T we have only came with the 5 speed NAG1 transmission with triptronic. I normal automatic mode, I feel it shifts into the highest gear it is able to way too soon. Lugging around in 4th gear @25 MPH has happened. Apparently this is a common issue.

It honestly wasn’t awful once you got used to it, but it had a large learning curve, and even then it still sucked. The latest software is much closer in operation to a conventional automatic, but it still a different feel. It’s really unfortunate that Ford bungled these so badly since I think the double clutch system has a lot of advantages over traditional automatics if people would give them a shot.
