Sonnax 44912-03K Oversized TC Limit Valve Kit with Sleeve

The Sonnax 44912-03K is an oversized TC limit valve kit (torque converter limit valve and sleeve kit) for automatic transmissions. It repairs a worn TC limit valve bore, which can cause a loss of converter release oil pressure.

Key Features:

• Oversized valve and sleeve design gives the valve extra support to reduce future valve wear
• Restores normal converter charge and cooler flow
• Corrects converter overheating problems
• Salvages pump covers with worn TC limit valves or bores
• Also serves late-model steel valves
• Kit contents: valve, sleeve, spring and retainer plate

Installation note: The bore must be reconditioned with the matching Sonnax tooling before the kit is installed. Sonnax warns that extreme wear of the OE cast pump bore may be beyond what reaming can fix. If the wear gap exceeds .094", the pump must be replaced.

A worn TC limit bore can lead to converter drainback and low release pressure. Low release pressure can drag the converter lining and cause engine surge, pulsation or stall. This kit restores proper release oil pressure.
