The rpm @65mph is about 2600...too high to be in overdrive.
Thanks for the info Drifter420. That makes sense about the pressure. So, basically the */C isn't doing anything until the boost goes above atmos. pressure.
As far as the TCC solenoid, that'* what I suspect too. From other posts, that seems to be a common problem. But in the other posts, everybody else seemed to be having problems coming out of overdrive, which is the opposite of my problem, so I thought maybe it could be something else.
Does anybody know how much a TCC solenoid costs? I guess I better by a shop manual, because I don't know where the TCC solenoid is or what it looks like
