The control sleeve assembly opposes TCC solenoid pressure to modulate apply and release of the torque converter clutch. As the sleeve wears, the solenoid will push the valve quickly, causing premature lockup, loss of power and bumpy/cycling apply. The oil reacting on the valve within the sleeve is regulated converter apply oil. If the sleeve is extremely worn, apply oil pressure is reduced as it leaks at the sleeve. When the sleeve wears and causes the valve to hang, the TCC will not apply with required pressure, and overheating or slippage occurs. Sonnax TCC control plunger valve kit S16507C restores hydraulic integrity of the assembly. Sleeve is manufactured from highly wear-resistant aluminum alloy; Hardcoat anodized aluminum combats premature wear; Drop-in Zip Valve™ parts install quickly and easily
