I changed out the transmission fluid yesterday. I had a TCC solenoid on hand which turned out to be the wrong one. I bench tested the original. It was working fine and I left it in. Once the old fluid was out I could see how dirty it was which was pretty bad. After putting in the new fluid the tranny shifts fine. Thanks for all the advice.
