TC Limit Valve & Sleeve Kit

TC LIMIT VALVE & SLEEVE KIT (45RFE)

Symptoms:

  • Delayed engagement
  • Loss of power
  • Engine stall
  • Low TCC release pressure
  • Loss of fuel economy
  • Low cooler flow
  • Overheated converter

Cause:
Severe wear of the TC limit valve bore results in low oil flow into the converter circuit.

Correction:
Oversize the bore with the Sonnax tool kit and install the TC limit valve kit to restore proper release oil pressure.


Severe wear of the TC limit valve bore in listed Chrysler units results in loss of converter release oil pressure. Reduced release pressure at low speed and idle will drag the converter lining, causing engine surge, pulsation or stall. Low release pressure at cruise affects and limits efficiency, often increasing RPM and reducing fuel economy. If release pressure is low enough, the converter lining may drag enough to glaze the lining.

A worn TC limit bore contributes to converter drainback issues. Sonnax TC limit valve kit provides extra support for the valve to reduce future valve wear, restoring normal converter charge and cooler flow, plus correcting converter overheating problems.

Note:
Kit also serves late-model steel valve.

Kit Contains:

  • Valve
  • Sleeve
