It's a Bronco thing.

Love the “dogleg” crawl gear. Sure hope this thing’s as good as I want it to be... Might convince me to trade in my Tacoma.

As I just commented on the FP, reverse and 1st would ideally be across from one another for rocking your way out of a bad situation. Very happy to see this layout.

Hadn’t thought of that, but it’s an excellent point.

It’s just a shame Ford is so terrible at transmissions.

Would assume it’s some sort of SM465 -esque 6.55:1 or lower. The manual Jeep has a 4.7:1 1st gear, and with the Rubicon’s 4:1 t- case and 4.10s gives it a nice crawl ratio (~77:1) . For the Bronco, a ssuming a 6.55:1 low gear, with a s tandard 2.72:1 t- case and 3.73s (Ranger gear ratio) it’d be worse but not bad (~ 66:1). 4.10s would make it it a ~ 73:1 crawl ratio .

I think Ford has it right if they give it a 6.5-7:1 low gear with a 2.72 t- case. 4:1 t- cases aren’t the best in some situations (same with the 2.72). It’s a big downside to the Rubicon box.

And if someone wasn't paying attention they would put it in C not R to drive away in that configuration.

I’ve never successfully fully rocked a manual. Seems like that would be hard.

It’s definitely a pain, but I’ve done it in both snow and mud.

So the C stands for “ C all- the- tow- truck position because it’s still a Ford?”

Haha - which is more/less reliable: Ford or Jeep?

I was thinking C stood for Cruise since at 3 or 4 mph, it may last awhile.

In what cases is a 4:1 t-case a downside? I’m trying to figure out why the t-case gearing would really matter compared to overall gearing and coming up empty.

I get that they mean C for Crawl but I’ve never really called low gear that. Every vehicle I’ve driven with a low gear it was simply labeled 1 or L.

I’ve always called it Granny though - Had an 87 F150 with with the T18 with Granny, the 300 straight 6 and 4x4. When you put that thing in granny and 4x4 low it would climb anything but redline at a slow walk.

It’s a Getrag - not Chinese made.

The lawsuit is over the Getrag MT-82, right? How do we know this will be any different?

davesaddiction @ opposite-lock.com > Just Jeepin'
06/11/2020 at 15:13

My mistake - missed the fact that the MT-82 was also a Getrag...

Found this:

The transmissions are designed by Getrag and assembled by the Chinese company but the quality of the parts used inside are specified by Ford themselves and they chose to go downgrade from of the materials (the shift forks seem to be a major culprit).

These things were going to have problems no matter who built them. (I’ve read the assembly of the units themselves are actually fairly good/decent for the price point).

Granted the modern transmissions with additional gears has benefited a 4:1 case making it more useful, but the manual Rubi is still a 4spd + double OD box. It really depends on what you’re doing. 4:1 is a lot gearing for mud (or when you want wheelspeed like wet/muddy hill climbs) but not enough to do somewhat hardcore things, let alone serious crawling. You’re still apt to fry the clutch if you really want to really crawl. For wheelspeed, the further up in the transmission gears (using 3rd or 4th instead of 2nd or 3rd) you go the less sensitive the throttle input gets, so you have less throttle control.

I mean it works because it falls kind of in the middle use for your average user, but it’s not great. An underdrive box (oldschool Klune V), running a doubler setup, or something like an Atlas 4 speed tcase gives you a lot of options. It also helps keep axle gearing higher so you don’t have such a small pinion. Honestly most rock crawlers are auto (no clutch issues) and most Rubi’s are mall crawlers, so it’s kinda a moot point I guess.

Having three or four gears is ideal for a do-it-all rig. 1:1, 2.5-2.72:1 (mud/wheelspeed), (optional 4-5:1 for minor crawling), and 8-10:1 (technical crawling, esp w/fine control via e-throttle tuning).

F ord’s lousy quality due to cost-cutting is literally legendary .

But still in modern times , Ford can build neither a manual transmission , an automatic transmission , an Explorer that won’t poison occupants , nor a Focus RS with correct head gaskets . At my job, w e get fleet Explorers with loose trim panels and fleet Tauruses with improperly mixed antifreeze.

I have a friend that works in the rental fleet of our local Ford dealer, and they have a hard time keeping their rental/loaner fleet stocked because of how much the vehicles are in for service.

A friend in high school had a previous-generation F-150 with a granny gear, and he says they used it to pull down an old house once.

I had an 01 Ram 4x4 with the Cummins, NV5600 6 spd with a granny 1st, and 4.10 rears. In 1st and 4-lo it would literally pull up pavement, but it redlined at 4 MPH.

I believe it - we used that truck several times to pull down trees. Mostly as an anchor/guide when felling large trees near homes.

I’d lash a 100' rope to a tree and the other end to the truck and then notch the tree. Next the truck pulled tension on the tree and I cut into the other side. We had to have a watcher in the cab too because when the tree started to lean or crack I waved, dropped the saw and ran to avoid the kickback and the driver gunned it in 4x4 low and granny gear and it would give the tree just the nudge it needed to avoid what I wanted it to.

I was definitely not a fully insured professional and did this mostly for friend and family back when I was young, strong and stupid . The most harrowing was to take down a very old Maple that was 4' across and 60' tall and I only had about a 20 degree safe place to drop it between a barn and a propane tank.

That sounds exactly right, mine I could start it in low and get out and slowly walk faster than while it trundled along.

Mine was awful at highway speeds because 4th was a 1:1 so no overdrive. It would only do about 65mph tops and it was screaming at that speed.

There’s still a chance you get one that’s 100% problem-free
