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 15741-29K eliminates bore wear for renewed TCC and drivability performance.
