Description
45RFE / 545RFE / 65RFE / 66RFE / 68RFE TCC Regulator Valve Kit, Sonnax 44912-11K.
Does not fit ’19-later 68RFE.
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.
- 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
