TCC Priority Valve Kit
Description
Severe wear of the TCC regulator valve bore caused by oscillation of the OE valve allows regulated secondary line and TCC signal pressure to leak to exhaust in listed Ford and GM 10-speed transmissions. This wear minimizes secondary line pressure control resulting in overheated fluid, loss of converter feed pressure, TCC release concerns, TCC slip code concerns and potential transmission control module (TCM) errors.
Installing drop-in Sonnax TCC priority valve kit 105740-03K eliminates the leakage of secondary line pressure by creating a new conditioned bore area for the upgraded valve to operate in. The O-ringed end plug provides a positive seal and prevents critical TCC signal fluid from leaking to exhaust. Both of these Sonnax features restore normal TCC operation by reestablishing the hydraulic integrity of this circuit.
- Sleeve manufactured from highly wear-resistant aluminum
- Hardcoat anodized aluminum valve combats premature wear
- Annular grooves help center valves in bore to reduce future side-load wear
- Drop-in Zip Valve™ parts install quickly and easily

Symptoms:
- TCC apply & release concerns
- Overheated fluid
- TCC slip codes
- Low line pressure & TCC concerns
Cause:
Excess wear at TCC regulator valve bore and worn OE parts allows secondary line and TCC signal pressures to exhaust, resulting in loss of converter feed pressure.Correction:
Restore hydraulic control and renew TCC performance by installing Sonnax drop-in TCC priority valve kit.Details
