    Does anyone know what the three ratios are for a TH350 from a 76 Blazer. Also when in high does the NP203 have a 1:1 ratio? Any information would be greatly appreciated

    If in doubt, gun it.

    i think first in a t350 is 2.52
    second is 1.52
    third is direct 1:1
    yes high range in a 203 is direct 1:1 as it connects the input to the output
