TCC Regulator Valve Kit

Fits ’18-earlier only in 68RFE.

In Chrysler 45/545/65/66 and '18-earlier 68RFE transmissions, various converter concerns result from the OE design of the TCC regulator valve. There is minimal valve-to-bore sealing at the line pressure to converter feed circuit, which allows critical apply fluid to leak past the valve spool and directly to exhaust/sump. Typical cores show low vacuum at this critical TCC apply circuit and confirms the issue of poor valve to bore sealing.

Sonnax enhanced drop-in TCC regulator valve kit 44912-11K incorporates an extended spool for additional sealing support at the critical interface between the line pressure circuit and the TCC apply circuit. The Sonnax valve kit is designed as a quick and inexpensive repair for pumps showing initial signs of wear or as a preventative measure to extend the life of the pump. The kit also includes a sturdier accumulator spring retainer, as the OE retainer is often damaged from excess spring force.

• Hardcoat anodized aluminum valve combats premature wear
• Lengthened critical spool for additional sealing area and wear prevention
• Thicker accumulator spring retainer to replace thinner damaged OE accumulator spring retainer
• Drop-in Zip Valve^™ parts install quickly and easily
