Sonnax 22771A02K Lube Regulated Pressure Regulator Valve for Chrysler Transmissions

The Sonnax 22771A-02K lube regulated pressure regulator valve is engineered to improve torque converter performance and prevent fluid drainback issues in Chrysler automatic transmissions. This precision valve features an integrated check valve design that addresses common converter charge and lubrication problems.

Key Features:

• Internal check valve allows immediate oil flow to converter charge circuit upon startup
• Enhances converter feed and lube oil flow during critical low RPM and high load conditions
• Prevents fluid drainback when engine is off, reducing converter drain issues
• Provides improved stability and lube regulation over worn OE valves
• Direct replacement for standard size applications

Application:

• Compatible with 42RE, 42RH, 46RE, 46RH, 47RE, 47RH, and 48RE transmissions
• Also fits A727, A904, A518, and A618 models (1978 and later)
• Works with 30RH, 31RH, 32RH, 36RH, and 37RH variants

Installation Notes: For maximum benefit, Sonnax recommends pairing this valve with manual valve 22771-09. To prevent converter slippage, restricted cooler flow, or hydraulic noise, remove the cooler line drainback valve during installation. For severely worn valve bodies, consider oversized valve kit 22771A-07K.
