PART # 42987
Fits AODE, 4R70W, 4R75E, 4R75W
With the New SuperTuff plate, the new smaller .073" 1-2 feed hole works as a stock replacement on the later model 4R75’s that came with a smaller 1-2 feed hole, and factory accumulator springs. It replaces stock plates found in most V-6/small V-8 units from 2008-current production. The good news is you can now keep your late accumulator spring set up if you just want to change the stock plate without firming the 1-2 shift. you can always use the 42987 as a start and if you want it firmed up, just drill the .073" 1-2 feed orifice to whatever size you want.
