Description

It fits the 45RFE, 545RFE, 65RFE, 66RFE, and 68RFE models. This spring is crucial for limiting converter release pressure, and a broken spring can lead to various transmission issues such as engine stall, delayed engagement, and loss of power.

It is engineered to prevent fatigue and breakage, ensuring consistent limiting pressure between 115–125 psi. This part is intended to replace weak or broken springs in early-style OE aluminum valves.
