Description
Gear lever, robotic transmission shifter for Citroën C1, Peugeot 107 and Toyota Aygo Automatic. With speed sensor.
Product Overview
This gear selector lever is designed for robotic/automated manual transmissions used on small city cars from the PSA/Toyota collaboration. It combines the mechanical selector mechanism with an integrated speed sensor to provide gear selection input and vehicle speed information to the transmission control. Ideal for professional workshops and experienced DIY mechanics who maintain Citroën C1, Peugeot 107 and Toyota Aygo models.
Key Benefits
- Direct replacement for original equipment part numbers commonly used on C1 / 107 / Aygo models.
- Includes speed sensor for accurate information to the transmission electronics.
- Restores precise gear selection and improves shift reliability when original selector is worn or faulty.
- Saves labor time compared with repairing individual internal components when the assembly is worn or damaged.

Symptoms Of A Faulty Selector
- Inability to change gear or selector sticking between positions.
- Transmission warning light or gearbox fault messages on the dashboard.
- Unusual noises or grinding when selecting gears.
- Incorrect gear indicated versus actual gear engaged.
Why This Part Fails Most Often
Failures usually result from mechanical wear of detents, bushes or linkage components, damage to the internal position sensor or electrical connector corrosion. Moisture ingress and dirt accelerate wear in the selector assembly. Repeated heavy use, rough gear changes or impact to the center console area can also cause premature failure of the mechanism or speed sensor.
Installation Recommendations
Replacement is straightforward for a trained technician or confident DIY mechanic with basic workshop tools. Typical procedure:
- Park the vehicle on a level surface and apply the handbrake.
- Disconnect the battery before starting work to prevent short circuits and avoid accidental activation of electrical components.
- Remove interior trim and console panels to access the selector assembly.
- Unplug electrical connectors and detach linkage or cables from the selector.
- Unbolt the selector assembly from its mounting points and remove the unit.
- Fit the replacement unit, reconnect linkage and electrical connectors, then reinstall trim.
- Check function: verify gear selection in all positions and confirm there are no fault messages. Test drive to ensure correct shifting behavior.
Use quality fasteners and ensure connectors are clean and securely seated. After installation, inspect boot seals and surrounding trim to prevent moisture entry.
Notes For Professionals
When replacing a selector on robotic/automated manual gearboxes, verify that cable adjustment and linkage free play are set to the manufacturer’s specification. If a speed or position sensor has failed, replacing the entire selector assembly with the integrated sensor is often the most reliable repair. Always clear any transmission fault codes after replacement and confirm proper operation with a road test.
