Lube Regulated Pressure Regulator Valve
OE valve must match 1978 or later design
Description: Under extreme pressure or temperature conditions, the converter/lube circuit in Chrysler RWD units can be restricted by the PR valve. The practice of drilling a hole between passages is problematic. This outdated technique contributes to slow engagements or excessive converter pressure and low line pressure. The best way to improve oil flow is to replace the OE valve with this Sonnax valve, which ensures oil flow under extreme operating conditions and prevents drainback when the truck is off. Improves converter feed/lube oil flow at critical low RPM and high load conditions. Redesigned valve prevents fluid drainback and slow engagements. Helps charge the converter in Park. Includes installation instructions.
