My girlfriends got a 1995 3.4 v6, she has 3.08 gears, I want to swap in a 3.42 off of the junkyard, but cant find a way to calibrate the shifts/speedo. What about swapping a 3.42 geared v6 pcm into the car? Would that fix the speedo? Or who does do 3.4 tuning? Cant seem to find anyone:secret:

there were no 3.42 geared 3.4l v6's made you are out of luck there and 3.4's are all OBD1 so nobody will touch them.

Nope.. There was no Y87 option on v6's during the 3.4l years. All 3.4l's had drum brakes, open rearends, and 3.08 gears.
