I think I've asked this before. What year 4l80e wull work with my 03 Truck PCM? I know some years have TCM in the trans and I know there is repinning in the trans connector to do, but I'm not sure what year trans to use other than an '03.

Any 4L80 will work with the pcm in your truck.

Only the newer 6 speed tranny's have a tcm that's integral to the transmission.
