45RFE, 545RFE, 65RFE, 66RFE, 68RFE Transmission TCC Regulator Valve Kit Part No. 44912-11K In Chrysler 45/545/65/66/68RFE 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 Contents Valve Spring Retainer Symptoms: Converter concernsLockup concerns Cause: Minimal valve-to-bore sealing at the line pressure to converter feed circuit allows critical apply fluid to leak past 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. Correction: Remove multiple TCC lockup concerns by installing the Sonnax enhanced, drop-in TCC regulator valve kit that utilizes additional sealing area to prevent critical line pressure from cross-leaking to exhaust. A thicker accumulator spring retainer is also included to replace the often damaged OE retainer.
