I will have to be getting in there soon to change out a seal due to an annoying leak. My question is on the type of oil. FSM in the NP205 section talks about using gear oil, such as 80/90, while the front section on lubricants they talk about using ATF. What do you all suggest, for CA temps? Also, do you all have part numbers for the seals on these?

 

80-90 is fine for the 205. Any reference to automatic tranny fluid is likely refering to the pretend t-cases that are made of aluminum I don't have any part numbers, sorry. A decent parts store guy should be able to look it up though.
