1991 roadtrek 190

[brettb]

hello everyone, well this is my first post, me and the wife bought a used 1991 rt 190 popular with 242,000 km in the dash, runs great, and clean on the inside, doesn't stink, everything works, in the shop getting a lot of the rubbers replaced, well just about the whole front end and rear leaf spring shackles and so on, but i would like to know what everyone thinks is a good rear diff fluid and tranny fluid, thank you for any
