hey i have a 94 camaro and the trans is on its last leg, i might have a way to get a trans out of a 96 b-body that was wrecked for realy cheep, what will i need to do to do the swap? what are the differences between the transmitions? do i have to have the computer tuned for it?

The PCM and trans harnesses are different after 94. You need a 94 trans (not 93, or 95-97), unless you want to swap the entire PCM, harness, and trans out.

You can use it but you need to change the tailshaft, cooling line fittings, gear linkage fitting and then you need to run a wire from D6 (blue number 6 on the PCM harness) to the extra pin slot on the tranny harness. Then have your PCM burned to run with a PWM 4L60E.

well i do know a bit about transmitions and can work on them, can i just swap the entire valve body from my 94 4l60e along with the tailshaft and cooler lines and everything? ill still have the old transmition to use for parts

Yup, that works too.

ok sweet thats the plan then one more thing tho, is it a good idea... and even possible to swap the servos to the corvette ones too? it shouldnt be hard to do once the valve body is off right? just pop out the snap ring out and swap servos and of corse seals? sorry idk much about the gm transmitions

If it was a 5.7 Caprice/Impalla. It already has a Vette servo in it. If not its very easy to do and there is no need to do anything to valve body to do this mod. You just remove the retaining ring, then pull down on the rubber o ring with a flat head screw driver and then swap in the new one.
