Sonnax highlights its oversized lube regulated pressure regulator valve kit (#44912-15K) for Chrysler 45/545/65/66/68RFE transmissions. The company says this kit can restore pressure regulator action for line pressure control in all ranges in these transmissions.
The company says this valve has an internal check valve that ensures proper converter and lube oil flow under extreme “tuned” operating conditions, eliminating the fluid overheat and converter-related engine stalls at idle.
