I'm in the middle of a discussion on Facebook over the ESC module and when/where it's used. Used Rock Auto for reference and it spans '84-'95 over several models, several being the same platform...

I would do the same... I like the idea of actually being able to control the trans too, I'm actually considering replacing the 4L60 in my '92 with a 4L80E.

Ditto :D I'm running it on a 9.5:1 383 with Vortec heads, 454 throttle body and Comp 08-412-8 cam. 13,000 or so miles and no issues :)
