While not new to gm efi I am new to changing programming. I recently swapped from a 2.5
4 cyl to a tbi 350 in my 90 wrangler. I currently have a 5 speed but want to go 4l60 or 4l80.
My engine and computer is from an 87 4wd truck that had a th350 trans. I learned alot while doing the conversion and am looking forward to learning alot more now.

luckily, you can pull a trans and PCM from the same vehicle and it will all pretty much plug and play..... as much as a GM engine/trans will in a Jeep anyways.

Installing the engine was the easy part,the wiring took a while though. I reused the chevy harness and grafted it into the jeep harness and flex loom. Aside from a bad ground everything went very good and so far i have no electrical gremlins. Hopefully when I get the auto in it with a vss it will solve all my problems.
