ACDelco Valve Position Pressure Switch 24215111 — GM OE Direct-Fit Transmission Manual Shift Sensor

The ACDelco GM Original Equipment 24215111 Manual Valve Position Pressure Switch is a factory-style replacement that restores proper transmission/manual shift shaft position sensing on compatible GM vehicles.

This ACDelco GM OE switch is built to the same specifications used by General Motors and is recommended as the direct replacement for the original unit installed at the factory. Designed for compatibility with automatic transmissions, transaxles and manual drivetrain components on eligible GM models, it provides the fit, form, and function expected from OE parts while simplifying installation and troubleshooting when your vehicle’s transmission control system requires a reliable position input device.

How does this switch affect transmission shifting performance?

The valve position pressure switch reports the manual shift shaft or valve position to the transmission control system, helping the controller determine appropriate hydraulic pressure and shift timing. A properly functioning switch supports consistent gear changes and reduces erratic or delayed shift behavior caused by incorrect position feedback.

• Restores accurate valve/shaft position signals to the transmission control module
• Helps stabilize hydraulic control and shift timing across gears
• Reduces diagnostic ambiguity when replacing a worn or failed switch

What makes this ACDelco part a better choice than aftermarket replacements?

As an OE-recommended component, this ACDelco switch is manufactured to GM specifications for materials and tolerances, ensuring correct electrical characteristics and mechanical fit. That reduces the need for rework, reprogramming, or adapter parts commonly encountered with generic alternatives.

• Built to GM OE specification for consistent fit and function
• Quality control and materials aligned with factory standards
• Direct-fit design minimizes installation surprises or modifications

How do I install or program the replacement switch?

Installation procedures vary by vehicle; the switch typically mounts to the transmission or manual shift shaft and connects to the OEM wiring harness. For correct adjustment and any required relearn or calibration, consult a GM dealer or an ACDelco service center to ensure the transmission control module recognizes the new component.

• Mounts in the original switch location using factory fasteners
• Plugs into existing OEM wiring harness—no splicing when fitted correctly
• Contact GM or ACDelco service for programming, alignment, or torque specs

Will this switch work with my vehicle model and year?

This ACDelco GM Original Equipment switch is intended for specific GM transmissions and drivetrain systems; compatibility depends on model, year, and transmission code. Confirm fitment by checking your vehicle’s OEM part number, consulting an ACDelco catalog, or speaking with a GM parts specialist before ordering.

• Check OEM part number 24215111 or vehicle application guide for exact fit
• Suitable for vehicles that originally used the same GM OE switch design
• Dealer or parts specialist can verify application by VIN
