Extreme wear of the OE cast pump bore is possible and beyond the ability of reaming to fix. If wear gap exceeds .094", pump replacement is required.
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 44912-03K provides extra support for the valve to reduce future valve wear, restoring normal converter charge and cooler flow, plus correcting converter overheating problems.
Kit also serves late-model steel valve.
