The TCC pressure control plunger valve and sleeve assembly act to increase pressure to the TCC switch valve. When this control assembly wears, the oil driving the plunger valve and inboard control valve leaks to exhaust, resulting in decreased pressure to switch valve. This pressure deterioration can cause lock-up apply issues, TCC codes, and premature failure of the torque converter. Installation of Sonnax TCC pressure control plunger valve kit 102741-01K will arrest these leaks and reestablish appropriate TCC pressure control.

• Sleeve is manufactured from highly wear-resistant aluminum
• Hard-coat anodized aluminum valve combats premature wear
• Restores proper hydraulic sealing and pressure control
