Key Product Information
Additional Information
| FITMENT | Fits GM full?size trucks (Chevrolet Silverado and GMC Sierra 1500/2500/3500) for 2019–2024 model years equipped with a column?mounted electronic shift lever. In GM parts catalogs it is listed as the automatic transmission control and appears within the steering column assembly illustrations; verify by VIN and steering column options (e.g., tilt/telescoping) to confirm the correct control assembly variant. Chevrolet Silverado (2019-2024): 2.7L I4 (Turbo), 3.0L I6 Diesel, 4.3L V6, 5.3L V8, 6.2L V8, 6.6L V8 (Gas), 6.6L V8 (Duramax Diesel) GMC Sierra (2019-2024): 2.7L I4 (Turbo), 3.0L I6 Diesel, 4.3L V6, 5.3L V8, 6.2L V8, 6.6L V8 (Gas), 6.6L V8 (Duramax Diesel) |
| SYMPTOMS | Common failure symptoms include a 'Shift to Park' message even when in Park, vehicle electronics remaining on after shutdown, or intermittent need to jiggle the lever to recognize Park. GM bulletins attribute this to the park switch inside the shifter assembly not correctly signaling the BCM. |
| TROUBLESHOOTING | Before replacement, inspect the column shifter for free play and verify the condition of the internal park/position switch. Scan for BCM/Body DTCs related to park/shift position plausibility. If the message clears when wiggling the lever while in Park, the internal switch/lever assembly is a strong suspect. Also check the shift lock/BRK?TO?SHIFT solenoid and cable adjustment if applicable. |
| INSTALLATION | Disconnect the battery. Remove upper/lower steering column shrouds, then unbolt and unplug the shifter control assembly. Install the new control, tighten fasteners to spec per GM SI, reconnect the harness, and reassemble the shrouds. After installation, cycle the shifter in and out of Park several times with the brake applied and verify Park recognition and proper operation. Always follow GM Service Information (SI) for your VIN. |
| MAINTENANCE | |
| GENERAL NOTES | Catalogs may state 'Included with column assembly'—on some vehicles the control is serviced as part of the steering column. There are closely related supersession variants; 85055304 supersedes 85565585 in GM diagrams, while a sibling part 85055305 supersedes 85565586 for different column/options. If your truck uses a console?mounted Electronic Precision Shift system, this column?mounted control will not apply—verify shifter type by inspection or VIN. |
