Bore wear at the TCC control valve and/or sleeve in listed transmissions 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 driveability performance.

• Allows salvage of previously non-repairable worn valve bodies
• Highly wear-resistant aluminum sleeves provide additional valve support and stability
• Hardcoat anodized aluminum valves combat premature wear
