    What crawl ratio would a '96 with 4:88's and 35's would come out to be?
    I'm trying to figure out these 80's?

    A343F first gear = 2.804
    Torque convertor multiplier (or divider) ~2
    transfer case = 2.488
    diff = 4.88/4.1
    tire = 31/35

    Multiply them out.

    Hey thanks.
    I couldn't do the math 'cause I didn't know any of the ratios.

    The whole torque converter thing is not a constant. When the TQ is locked up you have to remove that (2) multiplyer. I like to use 1.5 instead of two. That way you self comprimise for when the converter is locked.

    Looks like around 51 to 1


    Tire size has nothing to do with low range.

    first gear x ring and pinion x low tcase gear set x the torque converter.

    2.804 x 4.88 x 2.488 x 1.5 = 51 to 1

    Some people dont use the torque converter to figure out low range.
