Transfer case fluid

    Sorry for the multiple and duplicate posts but I don’t think a lot of people spend time in the van section so I just have a quick question:

    Hello, I recently changed the transfer case fluid for my 96 Daihatsu Atrai S130V. It is the EFI engine with 4wd and automatic transmission with the push button transfer case. I have the original owners manual and I swear it translates to automatic transmission fluid for the transfer case, but when I drained it was definitely gear oil in it. Does anyone know if I am wrong or if the previous owner put the wrong fluid in it? I know with the manual transmission trucks and the two speed transfer cases it would be gear oil but it seems like this is different. Thank you for your help. I put the ATF in it and no issues yet but I really haven’t let the transfer case be worked hard since the fluid change. Thank you.

    Not sure on Daihatsu, but some manufacturers ran ATF in manual transmissions, and transfer cases. Chrysler first tried it around 73. AS a way to reduce friction, and increase fuel economy. Their testing showed it protected teh gears just as well as the 80wt, they had been specifying, and did give tem better mileage.

    Someone may have put the Gearlube in yours becasue it was noisy. It is a very common used car dealer trick.

    Gotchya, I put the gear lube back in so we shall see. It’s tough translating and doing stuff on these things sometimes.
