gear ratios for a ht70

[chessie4905]

What rpm is it shifting at? Some adjustment can be done at governor weights and springs if all the shifts are at same rpm. If just one or to are too high or !ow, then there is adjustment at the shift spring plugs if they have the stepped p!ugs; otherwise, shift spring/s need tweaked or changed. Trimmers and modulator will effect shift harshness. The 700 series use a governor just like the Hydramatic at400's used in GM cars and trucks in 60 through the 80's, just about twice as large though. Allison sold valve bodies for them set for different shift points or speeds according to engine governor settings. Don't know how much of that stuff is still available.
