ACDelco Manual Shift Position Pressure Switch 24215111 for GM Transmissions — OE Fit, Direct Replacement

The ACDelco GM Original 24215111 Manual Valve Position Pressure Switch is a factory-spec replacement that restores accurate manual-shift position sensing for compatible GM automatic transmissions.

This switch is engineered to the same specifications used by General Motors for original equipment, so it fits and functions like the part your vehicle had when new. It monitors the manual shift shaft position and transmits that information to the transmission control system, helping the drivetrain interpret driver gear selections. Built to OE tolerances and materials, the unit aims to deliver reliable performance and a service life consistent with GM standards.

How does this switch interact with my transmission?

The switch detects the manual shift shaft position and sends a signal used by the transmission control unit to confirm gear selection. That input helps the control logic coordinate pressure control and shift timing. Because it's manufactured to GM specifications, the switch integrates with factory wiring and connectors without modification.

• Direct replacement for the original manual shift position sensor
• Interfaces with factory electrical connectors and mounting points
• Provides position feedback used by transmission control strategies

Will this ACDelco part fit my GM vehicle?

This 24215111 unit is a GM-recommended replacement for specific models and years; fit depends on your vehicle’s transmission and original equipment part number. Verify compatibility by checking your VIN, OEM part number, or consulting an ACDelco service center or GM dealer. Using the correct OE-designated switch avoids splicing or adapter requirements.
