On the input shaft itself. You'll see a little recess behind the splines.

learn something new, thats why the transfer case is probably filling up with trany fluid.

ding ding ding . . . . and make sure the coupler lines up . 1 side i think has a machined flat section to line up and work with the o-ring on the input gear .

I new that just didn't know about o-ring ,
Changed seal when I rebuilt the transmission. It's a slow fill but no beuno situation...... Lol

 

[Kain]

it is a slow leak i checked , will get seal kit next payday

 

[Kain]

found it,,,,
This O-Ring fits inside the splined coupler to prevent oil from flowing via the inside of the coupler from the automatic transmission to the transfer case.

it goes on the input gear grove for it and then fits in the coupler .

Yep. I did one on the creamsicle before I traded it. Common problem

When I bought a seal kit for my NP205 some of the gaskets where not correct for it. Since my truck has the one year only 4L80E/NP205 combo the transfer case adapter and input shaft seal housing gasket was different. All NP205 seal kits are for the T400/NP205 combo, and not the 4l80E/NP205 combo . The input shaft seal was correct, but I had to make my own input shaft housing and adapter gasket.
