Trannies the same?
I'm watching a '96 SE that is for sale that has a bad tranny (won't shift past 2nd). I happen to have a transmission from a '91 Park Avenue, which is the 4T60E type (apparently Buick put the next generation stuff, like the L27, in Park Avenues before the masses got them).
Would my tranny work in the '96?
Thanks for any advice.

Yes as Pat stated the transmissions are the 4T60-E, But the wiring on the valve body and the pinouts in the connector may be diffrent and require some work...As well that Park avenue may have had a 2.84 gear ratio where the Bonnie most likely will have the 3.06 Ratio..

I put an '86 4T60 in my '90 SSE, which required repinning. No big deal, but fewer pins, of course, and none of the parts stores had a gasket to put back on it.
Isn't the drive ratio built into the transfer drive? Which is behind the valve body? And has 4th gear built into it? I went to a lower numerical ratio in the SSE with the tranny change, end result is slower off the line but better mileage. If I really got a hair, I'd swap the drive (I think).

It can be the Drive and Driven sprockets as well as the Final drive I believe... In a service manual it will tell you which drive and driven sprockets were used to obtain an overall final gear ratio... So yes with some swapping you should be able to change the gear ratio...
Do you have any service manuals that cover the 4T60-E?
