Cause:
TCC control bore wear allows pressure loss that results in drivability concerns.
Correction:
Recover hydraulic control and restore normal operation by reconditioning the bore and installing Sonnax lockup clutch control valve kit.
Bore wear at the TCC control valve and/or sleeve in listed units results in loss of torque converter clutch control. The TCC can remain applied, transferring shift shock, or can result in RPM fluctuations. Reconditioning the bore and installing Sonnax lockup clutch control valve kit eliminates bore wear for renewed TCC and drivability performance.
Allows salvage of previously non-repairable worn valve bodies
Highly wear-resistant aluminum sleeves provide additional valve support and stability
