tranny/t-case question?

[ironnut]

I swapped out a np203 for a np205 a couple years ago behind my th350. Im having problems w/ the tranny fluid being pushed into the t-case then t-case overflowss and make mess. Ill go through 3 qts of tranny fluid per week through the t-case. I cannot remember if their was a seal I could replace between the two. If so is it as easy as unbolt the t-case and swap seals??? Thanks

IIRC there is a seal and a bearing in the adapter. not sure what side the seal is on though.

There should be a big rubber o-ring on the TH350 tail end unless the 205 and 203 adapters are different that way.

A 205 I had had a seal on each side. One held back tranny fluid and the other held back t-case oil.

is that the same with a 700R4 and a NP241? Can they swap or tranny fluid drain into the T-case? Sometimes I wonder about this since my T-case is always full and the tranny seems to be low a little every few months.

Not to mention the t-case drips out the rear seal no matter how many times I change that stupid seal. guess NP241 is a leaker!
