I would put a 4L80E in it instead, it costs a little bit more but it can handle anything you throw at it.

Agree 1000%

You will have to modify the harness, and will have to add the automatic trans wiring to it, but that isn't hard to do, and you will most likely want to reroute some of the harness anyway to fit your application anyway.

Absolutely correct. All it takes is a transmission segment swap. Ridiculously easy to do with EFI Live or HPT.

You too? lol. I've killed and helped kill more 4L60Es than I care to remember.

I made an assumption that GM wouldn't add code for transmissions they knew they would never use in the car, but apparently I was wrong.
The good news is you won't have to buy a TCU because they are expensive.
Now you can focus on finding a low mileage 4L80E, Get R Dun!

Yup. It really is as simple as flashing a 4L60E transmission segment into the LS6 PCM. I've also put together other LS combos that "never existed" and flashed them....5.3 with a manual....5.3 with a 4L80E, LS6 with a 4L80E
