Are you anywhere near Monument Valley? I'm planning a ride back out there with my daughter around the first weekend in April.

I plan to do the 6L90 with TCM-2650 setup this summer God willing.
My 4.8/4L65e currently.
Plan is SBE 4.8 with a 6L90 Trans this summer 2022.
Then Fall 2022 would be LSA Swap with LS9 Cam and headers.

Please document whatever you come up with @banks53

The internet is missing some high quality info on this swap to make it super popular (unless it is just way to expensive to be reasonable in the end).

I will do what I can. One thing I have been told is I do some cool **** but I’m shitty with documentation. I’ve been researching the best way to do this swap. It’s 50/50. Most guys just swap the whole harness from a v8/6L80 truck and deal with reprogramming.

I’m finding it hard to find a v8/6L80 harness in tact.

So I already have a 6l80 4x4 trans that we are doing a 80/90 rebuild on. So that’s moving.

Plan is to use a 5th gen Camaro ZL1 converter.

Issue I am finding is info on if the stock 07-13 transfer case (3023LD NQH) will:
1) bolt up to the 6L80/90
2) t-case input / trans output spline info. Will the t-case input need changed? I’ve seen conflicting information about 27, 29 and 32 spline for 07 Silverados with a 3023 t-case.

obviously the following will need custom mods:
1) front prop shaft
2) rear drive shaft
3) trans cross member.
