Default Torque Converter Clutch Won't Lock Up - No DTC Codes??

Was getting an intermittent hunting in and out of TCC Lockup during initial setting of TCC Clutch for some time. It would go in-ou-in-out then lock up OK.

Now it locks up OK sometimes, then won't lock up at all. Makes no difference if at 46 mph or at 70 mph, or what position gas pedal is in.

Thinking the brake pedal switch may be the culprit since I'm getting no codes whatsoever.

Very puzzling

Checked the fluid idling hot in park....perfect and clean synthetic

Called my AAMCO guy that fixed it 2 years ago....said he would test drive and do an electrinic and hydraulic check on it Saturday at 9:00 AM...I'll keep everyone posted.

Sounds like your lock-up solenoid has bit the dust, the o-ring could have gone bad, or a broken wire.

Thanks Johnny

What the hell happened to the yellow vette in your signature?

PPG Yellow primer with black spray paint used as marker paint. Old school to let you know the areas you've sanded already.
Kinda' looks desert stormish?

I'll get around to painting one day.
