To diagnose on a 700-R4, you can probably disconnect the TCC plug to see if the problem goes away, but don't drive it that way for long, because they overheat and self-destruct in short order with the lockup disconnected.

Why do you suppose that the TCC trannies behave differently w/o the
solenoid connected than ones before TCCs became standard equipment?  Do
they build the converters "weaker" when they come with a clutch, because
they can get away with it?
