Description

45RFE / 545RFE / 65RFE / 66RFE / 68RFE Oversized TCC Regulator & Accumulator Valve Kit, Sonnax 44912-12K. 

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 oversized TCC regulator and accumulator valve kit 44912-12K incoporates an extended spool for additional sealing support at the critical interface between the line pressure circuit and the TCC apply circuit. Also included in the kit is an oversized accumulator valve and a thicker accumulator spring retainer. The Sonnax valve kit is designed to salvage excessively worn pumps showing significant signs of wear. 

  • Hardcoat anodized aluminum valves combat premature wear
  • TCC Regulator valve has a lengthened critical spool for additional sealing area and wear prevention
  • Thicker accumulator spring retainer replaces thinner damaged OE accumulator spring retainer

  • Accumulator Valve
