Re: Dexron in 1972 transfer case ??

Thanks for responses so far.

The transfer case is an NP205. Not good to hear that a poor seal can allow trans fluid to be forced into the transfer case. That may be an issue in this instance. How common is this condition - anyone else experience this, and to what degree/amount of fluid?

Re: Dexron in 1972 transfer case ??

Its a common problem in a T350 equipped 205 with the two seals on the coupler sleeve.. often because of a worn bearing on the coupler shaft or input bearing on the transfer case.. Mine made it 9 years after a rebuild before it started filling up my transfer case with dextron.. I have been to busy/lazy to fix it, (I just keep adding dextron to the trans)

Good thing is, you never have to buy fluid... just drain the excess out of the TC and pour it back into the transmission!
