First check wires then if not fixed replace solenoid. I had the OD
solenoid replaced on my A-500 (peice of fk'ing trash) and its shifted
fine ever since. (now the torque conv. is having a break down)
My OD solenoid did not shift once everything was warmed up. It shifted
once in a blue moon, till I had it replaced. All total cost was $300
The majority was labor. They had to track down the electrical problem.
I will admit that the shop DID say it was electrical. But I had them
replace the solenoid anyway.
may have just contradicted myself here but eh -- <shrug>
