ISSUE:
The 3-4 shift accumulators used in prior model year "AOD," transmissions are not used in 1990 "AOD," transmissions. The accumulator
feed hole in the main control assembly has been blocked. The 3-4 shift accumulator is not required.
ACTION:
Do not attempt to install a 3-4 shift accumulator piston in a 1990 "AOD" transmission because it is not designed to have one. It will not
correct a 3-4 shift concern.
