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.
