AW-71 repair 200 1984

84 245Ti/AW-71 250k miles

About to try an experiment... replace the o-rings on the transmission accumulator pistons, because gear selection is very "soft" when trans is cold. For example, it takes a few seconds to engage reverse first time in the morning. After it warms up, all shifts are firm.

I deduce that pressure is leaking around the accumulator piston o-rings when stone cold -- and heat expansion solves the issue after warm up.

I am not an automatic transmisison expert but I have done lots of 240 repair including previous valve body service (1-2 shift/ball valve repair).

Am I on the right track? And I wonder where I can acquire the new o-rings...

Thanks

Robert
