Okey dokey, I guess not much experience putting a 6L80 into an OBS truck here. I'll post what I learn as I go along to help the next guy out. Talked to PSwired--Patrick--from another forum. He's done the 6L80 into an OBS and graciously spent 30 minutes on the phone with me. Many thanks to him for his time and expertise.

I could maybe get the rod type shift linkage to work. (The '92 has rod linkage, the '95 has a cable shifter. Not sure which year is the changeover.) Doesn't seem like it's worth the effort at this point. I'll start out using an Ididit cable adapter for the stock column shifter, and possibly switch to a 2012 Malibu floor shifter with Tap up-down buttons later. I'm going to have Motech out of Vegas do the ECM programming and use their BCM setup for cruise control and tap up-down shifting. That'll keep everything as stock as possible.
