GM 10L90 TRANSMISSIONS
Q: What fails on them?
A: Valve Bodies
​
Valve Body Wear & Solenoid Issues:
-
As these transmissions accumulate mileage, intermittent harsh shifts become a frequent customer complaint—often traced back to wear inside the valve body.
Key components prone to failure include:
-
Weak or broken solenoid retainer clips
-
Sticking linear pintle solenoids and clutch control valves
-
Worn LPC (low-pressure control) accumulator bore
-
Excessive clutch clearance
