Compatibility And Function
Fits vehicles equipped with the factory robotic/automated manual transmission (AMT). The selector translates driver input into mechanical and electronic signals for gear selection and provides a speed signal used by the transmission control logic. It is suitable for workshop replacement on the models listed above and is often searched for by the part numbers shown.
How The Part Is Replaced
Replacement is straightforward for a competent mechanic or experienced DIYer with basic tools. General steps:
- Secure the vehicle and apply the parking brake.
- Disconnect the battery to avoid electrical damage and accidental activation.
- Remove the center console trim and any trim clips blocking access to the selector assembly.
- Unplug the electrical connector(s) for the speed sensor and shift position sensor.
- Unscrew the mounting fasteners, remove the old selector and install the new unit in reverse order.
- Reconnect wiring, reassemble trim, reconnect the battery and perform a function check and road test.
Installation Recommendations
- Use correct trim tools to avoid breaking clips and plastic panels.
- Mark alignment positions (if present) before removal to ensure correct reassembly.
- Check connector pins for corrosion and clean before reconnection. Apply dielectric grease if appropriate.
- After installation, verify gear selection and that the vehicle recognises gear positions; perform a short test drive to confirm proper shifting behaviour.
Reason Why The Part Most Commonly Fails
Failures are usually mechanical or sensor-related. Common causes include wear of plastic pivots and bushings, fatigue or fracturing of lightweight plastic components, cable stretch or linkage deterioration, contamination from moisture or dirt, and failure of the integrated speed/position sensor. Symptoms often include imprecise or stuck gear selection, error messages related to the transmission, or irregular shifting.
Tips For Mechanics And DIYers
- When removing the old unit, inspect surrounding linkages and bushings and replace worn parts to prevent repeat failures.
- Check the electrical connector and wiring harness for signs of heat or corrosion; repair as necessary.
- If the selector includes a speed or position sensor, verify sensor output with diagnostic tools before and after replacement.
- Keep the part numbers (89451-52020, 89451-52021, 1612500880, 1608025580) handy when searching for compatible components or cross-references.
