GM GENUINE PARTS Torque Converter Clutch PWM Valve 24227792 — OE‑spec direct‑fit for smoother lock‑up and reliable shift control

This pulse width modulation valve, supplied by GM Genuine Parts, replaces the factory-installed component and is built to meet General Motors' engineering and testing standards. As an electro-hydraulic control solenoid, it sits in the transmission valve body and modulates hydraulic flow to help manage torque converter clutch engagement. GM Genuine Parts are produced or validated to match original equipment fit, form, and function, making this valve a direct-fit option for the specified GM vehicle applications.

How does the PWM valve affect transmission performance?

The PWM valve controls the rate and timing of hydraulic fluid supplied to the torque converter clutch, which influences clutch apply pressure and engagement smoothness. Proper modulation helps the transmission shift and lock the torque converter more predictably under varying loads and speeds.

• Regulates fluid flow to the torque converter clutch pathways
• Modulates clutch pressure for smoother lock-up and release
• Helps maintain consistent shift quality across driving conditions

What are the build and compatibility advantages of GM Genuine Parts 24227792?

This PWM valve is manufactured to GM OE specifications, ensuring the electrical connector, mounting, and hydraulic interface match factory dimensions. It’s the GM-recommended replacement for the vehicle applications listed by General Motors and is backed by GM’s validation processes.

• OE-spec manufacturing for reliable fit and function
• Engineered and tested to GM quality standards
• Direct replacement for specified original factory components

How will I know when the valve needs replacing?

Symptoms that may indicate a failing PWM valve include inconsistent torque converter lock-up, harsh or delayed shifts, or transmission diagnostic trouble codes related to solenoid control. A qualified technician can confirm valve performance with diagnostic tests and fluid inspections.

• Watch for erratic lock-up or unusual shift behavior
• Transmission fault codes tied to solenoid circuits suggest testing
• Fluid contamination or electrical faults can impair valve operation

What should I expect during installation and maintenance?

Replacement typically requires access to the transmission valve body and adherence to GM service procedures, including fluid handling and torque specifications. Using the correct GM Genuine Parts valve helps ensure proper mating to the valve body and reduces the risk of leaks or electrical mismatch.

• Installation involves valve body access and vehicle-specific service steps
• Follow GM torque and fluid-fill procedures after replacement
• Inspect transmission fluid and filter when servicing the valve

Who is this for: The GM Genuine Parts 24227792 PWM valve is intended for owners and technicians who need a factory-matched replacement for the torque converter clutch control valve in compatible GM automatic transmissions. It’s suitable for anyone seeking an OE-spec part to restore correct hydraulic modulation, maintain transmission performance, and preserve factory fit and reliability.
