I think the atlas was developed as a lighter alternative to the doubler, the doubler being a 203 rangebox, mounted to a NP205 transfer case.The Dark Side of Will wrote: ↑Sun Jan 19, 2020 10:13 am Are you still looking at the NP203/205 doubler setup?
That's basically what the Atlas 4 speed T-case copies, right?
Novak says the 6L90E is 1 3/8" longer than the 6L80E

Don't forget the Quadrasteer. I just re-read a little bit of your thread... I had forgotten that you said the tow rating went UP on the Quadrasteer trucks. Wild.
I haven't forgotten about quadrasteer, there are a few problems that are difficult to overcome from a swap perspective, the biggest one being that the control modules and sensors are no longer made, and some of them are integrated with the steering column, which could be cheesy to adapt, or a royal PITA.
Novak's site is awesome, so much info on there.
