Sonnax TCC Regulator and Isolator Valve Kits

Sonnax TCC regulator and isolator valve kits assist in recovering hydraulic control and renew TCC performance. Severe wear of the TCC (torque convertor clutch) regulator valve bore, caused by oscillation of the OE valve, allows the regulated converter to apply pressure to your exhaust. This is a primary cause for TCC-related slip code and overheated converters. Exhaust pressure also diminishes line pressure, which can result in burnt clutches. Excess wear at the isolator valve bore reduces TCC apply pressure. Reconditioning the bore and installing a Sonnax TCC regulator and isolator valve kit will restore normal TCC operation by reestablishing the hydraulic integrity of this circuit. Order the kit recommended for your transmission application.

Features include:

* Sleeve manufactured from highly wear-resistant aluminum
* Hard-coat anodized aluminum regulator valve combats premature wear
* Isolator valve lengthened to operate in unworn portions of the bore
* Annular grooves help center valves in bore to reduce future side-load wear
