Yaris Corolla Gear Engagement Actuator

Error Codes:
P0900 - Clutch Actuator Circuit

The’gear actuator with OE code 3396064012 è is an original Toyota component, used in automated manual transmission systems. It is an electromechanical module designed to automate the gear selection and engagement operations, making the transmission electronically manageable via the control unit. È fitted on vehicles equipped with MM-T (Multi Mode Transmission), mainly in the Corolla and Corolla Verso versions with Diesel engines.

Technical specifications

L’actuator 3396064012 è composed of a die-cast aluminum body that integrates two independent electric motors: one for the gear selection movement (transverse), the’other for the’engagement (longitudinal). Both are connected to internal position sensors, called stroke sensors, which provide the control unit with feedback on the actual position of the selector.

The module includes:

• Two DC electric motors
• Stroke sensors on both axes
• Sealed multipole electrical connector
• Hardened steel drive shafts
• High-strength technical plastic internal gears

L’the entire actuator is mounted directly on the gearbox body via flanges and bolts. L’power supply and control are managed by the automated transmission control unit.

DIPA has a range of original and aftermarket quality spare partsà equivalent.

Functionalityà

The main task of the’actuator è automate the management of the mechanical gearbox in the absence of the clutch pedal. The system receives commands from the transmission control unit and transforms electrical impulses into precise mechanical movements, simulating the actions that in a traditional gearbox are performed by the driver.

L’the actuator operates in synergy with the control unit and the’clutch actuator, ensuring smooth gear shifts both inà automatic mode and inà manual sequential mode. The presence of position sensors allows for accurate control of the shifting phases and ensures the’adaptation to driving conditions.

Vehicle applications

Toyota

• Corolla
• Corolla SW
• Corolla Verso

DIPA recommends to always check the compatibilityà of the spare part before’purchase.

Typical defects

• Failure of internal motors, which causes difficultiesà of gear shifting or locking
• Malfunction of position sensorsresulting in loss of gear reference
• Wear of internal gearsoften caused by prolonged cycles or excessive loads
• Infiltration of’water or humidityàwhich damages the wiring or electrical contacts
• Alignment errorwhich canò bring the gear shift to neutral or to a fixed gear

In case of a defect, the system canò prevent the’starting of the vehicle or activate theà emergency mode (fail-safe), compromising safety and functionalityà of the transmission.
