By flipping said switch I get better fuel economy. This was the first real electric project on the car I've taken on by myself, usually I have my grandfather (who learned electronics in the navy in 'nam) help me. It's nice being able to drop my rpms by the flick of a switch. Torque converter lockouts are awesome.

Is it hard to do?

further explanation for the idiots here, please.

Well you see... The 700r4 I installed has one from the factory (they all do), I just never bothered to wire it up. The factory set up on the 1991 Caprice wagon my Trans came out of involved a vacuum switch, brake sensor switch, and some other complicated things. I said screw it and made a simple manual toggle switch.

The 700r4 trans comes from the factory with a converter lockout feature (torque converter matches engine speed and stays there) decreasing engine rpms due to slippage and decreasing heat. Factory there is a vacuum switch connected to the pedals that a automatically controls the locking, but in my frankenstein install, I just used a toggle switch.

This is just awesome. Thanks for sharing, and for explaining.

Is this sarcasm because here's an explanation: The 700r4 I installed has one from the factory (they all do), I just never bothered to wire it up.

Seems easy enough

No, actually it wasn't sarcasm, sorry if it came across that way. I was genuinely interested and appreciated your explanation. And I really do think it's awesome what you've done with Emma!

You've come along way since, what, 6mpg?

Oh! Sorry, the internet doesn't convey tone very well

Close to it. I use to get 9

how does it work in during a normal drive?
can the transmission shift gears with the converter locked?
obviously you can't stop with it on right? Seems like you'd have to pay attention to what you're doing with that switch

You get up to crusading speed (4th gear), flip the switch and the converter locks. If you slow down too much with the switch on, you stall the engine. I don't think it will shift.

that's what I figured, but I figured I'd ask since automatic transmissions are all a little different and I don't claim to fully understand the operation of any of them

Well, on a different topic I wish it was a manual.

my understanding from your other posts on this article was that you installed this transmission yourself, was swithching to a manual more work than you were interested in doing or were there other factors in your choice?

I wasn't too concerned with the amount of work because to even get this Trans to fit I had to cut a driveshaft, move brackets, and mess with the engine. The big factor was cost. I would have to go out and buy all the required parts for the swap (all the plumbing, different pedals, a transmission, bell housing, new center console, etc). By my calculations that would cost around $2000 if I'm lucky. The transmission I installed was $75.

I will look forward to some new MPG numbers! You'll surely bust into the teens now? :D

I was getting 16ish before this switch. I'd like to see 18.

oh, that'd be pretty nice.
