Re: 1980 Chevy C10 - Ugly but Functional

I have only worked with the older 99-02 pcm. Do some research on what you need for the 4l80e and pcm. At some point the transmissions got their own controller and some guys have had difficulty making different year pcm and tcm working together.

At the same time, a 4l80e controller from jakes transmission is $180 if it becomes a real problem.
