Just took off the inspection / bolt-up cover for the flexplate/torque converter and the flywheel and torque converter are both spinning with the engine.
If I engage the TCC lockup clutch, I get a zinging/whizzing sound that I never got before. Could that mean I have a torque converter or maybe fluid pressure problem?
EDIT: I should add that since this was rebuilt, there were times it would take a second of idling in gear for the pressure to build and allow for it to move. Could I have a bad TC drain back valve?
