Re: T-case adapter needed

wow, that's a different request...

You might have an easier time with a divorced transfer case....

Re: T-case adapter needed

What would I add to the in-put side of the T-case to connect to the tranny?


Thanks,
Garvin

Re: T-case adapter needed

Won't he still need to swap output shafts in the transmission since it's a 2wd?

Re: T-case adapter needed

measure and check once you pull the tailshaft off and put the adaptor/tcase on you need to see how much spline engagement you have.

I will be running a 2wd 4l80e with my np205 using a fig8 th400 adaptor.

This adapter is for a Pre-'97 4l603. The '02 model that I have has a 6 bolt tail shaft.

Re: T-case adapter needed

Never mind TH400 is also a 4 bolt. Any info on turning a 208 in to a divorced setup?

Why would you want to? If you want divorced, just get a 205.

Re: T-case adapter needed

Is the VSS threaded or is it set up like a crank/cam sensor for a LSX? I might try and fab an adapter with a VSS when I get back to the states. Is the shaft free floating between the tranny and T-case? Are there any bearings or seals on the any of the adapters?
