Well here goes nothing.
Car is a '95 LT1, auto
I want to swap in a built 4L80E, without a MVB, its a street car.
So far I cannot seem to find out whether there is software for OBD1 PCM that will work a 4L80E. I know there is some wiring magic that needs to happen, that is not an issue, just concerned about the tuning aspect.
Thoughts, ideas, but no lulz.
