Well I just got a NNBS and 1 of the first mods I want is a 6spd tranny. Iv pretty much got the mechanical end figured out. With the elctrical how would I use the HD tcase. Would it as simple as swaping the 4wd **** and getting BCM reflashed?
My plan is to find a wrecked HD for the LY6/6L90e/Tcase and wiring harness.
This is going tobe a long term as the powertrain warranty is still good for another year and half.
Also another big question is. Do HD have a different Tcase for the floor shift and push button?
Any info or suggestions are welcome.
I have other ideas like rewiring a 6l80e/AWD harness to 4wd.
But as of right now they're just ideas nothing is set in stone.

 

did you ever do the 6l90 swap
