The torque converter limit valve spring in the Chrysler 45RFE, 545RFE, 65RFE, 66RFE and 68RFE pump often breaks, and is not serviced separately from OEM. 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 of the Sonnax torque converter limit spring 44912-02 provides high allowable working stresses, preventing fatigue and breakage. Sonnax modifications to the spring design ensure that the critical operating load falls within the recommended design heights to maintain limiting pressure consistency and that the spring will accurately limit converter release pressure to 115-125 psi.
Fits OE aluminum valves found in early-style units only
