Signs your 6L80E/6L90E is failing
Catch these early and you replace one transmission, not a transmission and a tow bill.
A vibration around 35–50 mph when the converter locks up.
Often a failed 3-5-R clutch or its seal.
Valve body or control module issues.
Worn clutches or low line pressure.
Control module or solenoid faults. Scan the codes first.
Leaks lead to low fluid, overheating and fast wear.
