So......does anyone know what else I would need? The truck is mostly complete except for the engine and seats and the crashed rear so I can pretty much get watever I would need.
So if anyone knows what I would need to get off of the truck let me know because I plan on going to go see it again later on.

The owner has done it to a rclb

 

Computer reflash from the dealer to get the 6l80e programming is alll i was told besides the mechanical parts. Same as putting a 4l80e in a NNBS

 

i would think u would need the driveshafts right?

 

Get the harness off the truck as you'll need it to run the wires to the 6l80. The TCM is internal to the 6l80 as well, so that's good. You'll need the column shifter stalk as well as it has the TUTD selectors. Might need the cluster as well.

Get hte rear cross member and drive shaft if it was 2wd.

 

So I have a 2WD 6L80 (w/ converter), tranny crossmember, and TUTD shifter. I would need a PRNDM cluster so that it would look stockish, and I would need a custom driveshaft.
I'm also gonna need to take it to the dealer to get it reflashed for the 6L80.

what else do I need? anyone done the swap that could provide some info?

 

Ive got the same goals as you. I already have the 6L80, but need all the other hardware necessary to get it up and running. Im definitely interested in seeing what others have to say about this

 

I want to do it too but I just dont know if I have everything or have all the steps down to do the swap.
