Any one had any problems with tcase fluid getting into the tranny via bad seals? This is a big concern for me.

np205 tcase fluid in th350

you do not want gear oil in the auto tranny.
Never had gear oil in the tranny but when I picked up my NP205 I was surprised to find ATF fluid in it. I pulled it from a 72 for my 78. I guess it doesn;t hurt to run ATF fluid and I figure it would prevent any problems if the fluids mixed.
some people dont know what goes in so any oil does at the time. that tcase that old should be gear oil. and just change the seals while out. you dont want to swap it out again any time soon as its big and heavy.

Never seen that happen, usually the other way round, but you might want to check the vents on your transfer case. May be plugged allowing pressure to build, pushing gear lube into tranny.
Good point Rusty Parts. Also GM calls for gear oil in the np205.

There is nothing wrong with running ATF in a 205. It was factory spec for some years.
Interesting... do you know what year ATF was called for?
all 205's same in side . so atf or gear oil as you wish. just run it like you would and check to make sure case isnt over heating . if so might want to run gear oil.
