    Doing a doubler swap and wondering about fluid type to use. Detron ATF or 89-90 gear oil? Thanks for any info.

    I think it is 90,but not sure. Pretty sure it is not ATF-too thin, I think

    ATF is way too light for a NP205!

    1 ton '87 Chevy SWB in the making!

    atf was speced as the fluid in the 80s
    lighter fluid = better fuel economy
    I use the 80 90 but a synthetic would be ideal for those that dont change the fluid regularly
    i buy gear oil 20l at a time and have the pump, when I used to play every weekend I had to drain the water fairly frequently.

    I've always used 80-90w. I think got that from the Haynes manual.

    That is why I was asking. That it spec. do different fluids based on years? I'm going with 80-90 gear oil.
