Just put the 6l80 back together for my first rebuild. The Torque Converter filled the trans up with small sparkly metal pieces and gouged out the pump and bell housing along with 4-5-6 clutch pack being burned to the extent of no friction material left. All other frictions were good. The only changes from stock was Sonnax 4-5-6 apply upgrade, Raybestos frictions, changed from the 7 balls to 8 balls with newer separator plate, billet TCC stock stall. Disabled DOD(AFM) with TCC lockup only in 4th 5th.
I used HPT to do the clear, reset, fast learn etc.
OK problem is I'm getting a "P0974 - Shift Solenoid A Control Circuit High (Pending, Current, Permanent) Controller Type ID By OS: 60".
It may drive fine for a while then push the code and loose first gear going into 2nd. All other gears change fine. When I clear the code it will sometimes clear and drive ok and sometimes go right back into 2nd gear.
Now question is, will HPT read the Shift Solenoids 1 and 2? I have been searching and I can not seem to ask the right search question to find out.
Should I try a new TEHCM?
Thanks for any guidance.
