Can't control tcc (un)lock? Driving me crazy. Please help
I recently inherited from my late brother his 2001 t/a A4. Here's the specs:
Ms4 cam
Afr heads
Built 4l60e trans
4k stall
12bolt Moser 3.73
What's happening is the tcc locks up at 40mph cruising around and I currently have it to lock at 50mph (I knit that's high but was going to test it out)2001 trans am 20210514 gear and shift pts lowered tire diameter changed.hpt from 0-25% throttle. I raised the p0121 airflow max 76kpa and min 0 but still nothing based on another thread I read on here. Idle kpa is 10.3-10.8psi or roughly 76kpa
Tire diameter ratio is near spot on and mph matches GPS.
Attached is a copy of recent tune. Any help is greatly appreciated.
