c5wagner,
thank you very much for your help. I think I understand what I have to do to get my Dad's truck running now!
Off to the wrecking ard to find correct ecm.....
I think you would be wise to try to get 94/95 pcm that is closest to what ever vehicle the 95 4l80e came from. That way the transmission will be happier and the motor is the easy part of the swap. You can tune on the motor side and if you are off it runs crappy, if things are off on the trans side you could ruin the trans.

Last question....does the ecm determine trans or memcal?
The computer is pcm, power control module ( I think I used the right wording ) and it controls both the engine and the trans. The chip needs to be correct for both the engine and the trans. When people burn a new chip they are mostly working with the eng side although some of the deeper guys do work with trans. When you go looking for new pcm make sure to get the mating harness ends ( red,blue ) as they are different than what you have with your 7060. If it seems like a lot of work changing to 7427 it is well worth it in the long run.
