Sonnax 44912-02 Torque Converter Limit Spring for Chrysler 45RFE 545RFE 65RFE 66RFE 68RFE

The Sonnax 44912-02 torque converter limit spring replaces weak or broken TC limit springs in Chrysler 45RFE, 545RFE, 65RFE, 66RFE, and 68RFE transmission pumps. The OEM torque converter limit valve spring in these units often breaks and is not serviced separately from the factory.

Function and Benefits:

• This valve limits converter release pressure
• A broken spring can cause the valve to become stuck and result in converter clutch release complaints
• The improved design and high-quality material provides high allowable working stresses, preventing fatigue and breakage
• Modifications to the spring design ensure that the critical operating load falls within recommended design heights to maintain limiting pressure consistency
• The spring accurately limits converter release pressure to 115-125 psi

This upgraded replacement spring offers superior durability compared to the original equipment spring, providing reliable performance and eliminating torque converter clutch release issues caused by spring failure. Ideal for transmission rebuilds and repair applications on Chrysler automatic transmissions.
