Yeah but does that gasket seal the fluids from the two? Ive never had a 208 off the truck, but the 203 I had off had a gasket, but it left the center of the T-case adapter open and used a seal on each end. One in the case and one in the trans. Least I think there was one in the trans. I know the T-case had one for sure. Its been awhile. There is a bearing in there on the 203 doesnt that ride in ATF?
I realize there is a gasket between where the flanges of the tranny and transfer case come together. But It seems NTOLERANCE is saying they are both sealed, but bt83rc is saying they are open to each other. So which is it I pulled a 208 from a NP 435 that I'm putting in my truck, and also the 208 from my current 727. Can't remember if the 208 from the manual leaked out the front when I pulled it out, but the auto 208 did for sure.
I dont think they should share the same fluid they may use the same fluid but not share it .There should be a gasket between the cases ,they should each have there own input and output shaft seals..........Jason
They don't share the same fluid. The seal between the two is just to keep the from leaking out from around the T-case adapter. The T-case has its own fluid.
I had a 727/208 combo and when I took it apart the 208 held its fluid when sperated from the auto. I changed to a 435 and put the same 208 behind the 435. The 208 has ATF in it and the 435 has 80W-90. I think a 203 uses 10W-30 or 10W-40, if the wrong fluid is used the certain parts of the 203 won't be oiled properly.
