TCC Priority Valve Kit for Ford and GM 10-Speed Transmissions
Sonnax TCC Priority Valve Kit features a solution for severe wear in the TCC regulator valve bore caused by oscillation of the OE valve. This wear results in regulated secondary line and TCC signal pressure leaking to exhaust in Ford and GM 10-speed transmissions, leading to overheated fluid, loss of converter feed pressure, TCC release concerns, TCC slip code concerns, and potential transmission control module (TCM) errors.
