Has anyone done this? I appear to be able to change solenoid operation (FB2F-FB36 switches make up the solenoid truth table) and can use the line pressure mode tables to make line pressure suit an '80. Am I missing anything?

Thanks!

Other than inverting the Shift B solenoid logic, the only other significant change is the wiring
updates at the transmission connector. The 4L80E TCC lockup solenoid is on Pin S, which will
be unpopulated on a 95 LT1 application.

I've done a few of these swaps on LT1 powered cars (mostly B-bodies), and they have all gone
quite smoothly. I've got another 4L80E sitting in the back of my garage now that's going into
a friend's '96 LT1 powered wagon that is used for towing. The 4L60E in there is getting pretty
tired, and we'd like for this to be the last trans swap it gets for a long time.
