4t60e swap 96-99

[bob442]

Hey guys, I know I'm somewhat of a tranny guy but I'm getting mixed answers on swapping in a newer trans 99 gp 3100 to a 96 gp 3100, I havent compared the codes yet but I'm told that the lockup strategy changed in 97, then I was reading on beretta.net and 3400-modified was saying he's swapped 2 99 4t60es into 95/96 cars with no problems. Thoughts?.

it did change somewhat. the newer transaxles have a torque converter that even when locked up is in a constant state of slip, dont to minimize driveline vibrations/harshness into the passengers.

personally, i hate it and it seems like it would unnecessarily heat up the ATF for no reason. i like full lock.

i don't think anything changed electrically, though you may need to use the shifter position switch that is currently in the 96. that should directly swap though.

Yeah that's not hard to swap, I just want to know 1234odr will work properly
