Cause:
TCC regulator valve bore wear allows loss of crucial apply pressure.
Correction:
Recover hydraulic control and renew TCC performance by installing Sonnax TCC regulator valve kit.
GM vehicles equipped with 4L80-E and 4L85-E transmissions may exhibit problems such as TCC shudder, burnt converter linings, TCC apply and release concerns and related codes. These issues can often be caused by critical pressure loss due to excess wear in the TCC regulator bore. Installing Sonnax TCC regulator valve kit 34994-01K shores up the hydraulic integrity of the TCC control circuit to return robust TCC operation.
