Removing and refitting the Quickshift robot on Trafic, Master and Vivaro

On Trafic 2, Master and Vivaro vans, the Quickshift robot (actuator) comes off without touching the gearbox. The job is quick once access is clear, but one refitting detail often causes lost gears: the mounting spacer.

Before you start

  • Put the gearbox in neutral.
  • Depressurise the circuit: with the diagnostic tool, or unplug the pump and leave the vehicle standing for 48 to 72 hours.
  • Have something ready to catch the oil and plug the fittings.

What to disconnect and remove

  • The robot connectors and the speed sensor.
  • The plastic control rod to the gearbox (ref. 7701476234).
  • The hydraulic pipe going to the gearbox (plug it straight away).
  • The small bracket at the front of the robot.
  • The Torx E12 screw along the accumulator.

The fixings and the spacer

The robot is held by 3 × 13 mm screws and 1 × 10 mm screw. On 2.0 dCi engines, the latter goes through an aluminium spacer under the robot (about 16 mm high and 20 mm in diameter). On the 2.5 dCi there is usually none and the screw is 13 mm, but this is not an absolute rule: note what you find on removal.

Always keep the spacer from the old robot. If it is missing or loose, the robot moves on its mounting, no longer has the force to push the arm, and loses gears.

Allow about 20 to 30 minutes for removal once the front end is off.

Refitting

  1. Refit the robot with its spacer, if there was one.
  2. Tighten all fixings, including the front bracket and the E12 screw.
  3. Reconnect the hydraulic pipe, control rod, speed sensor and connectors.
  4. Set the oil level: 34 to 38 mm above the reservoir joint when cold. See robot oil level, oil change and filter.
  5. Carry out bleeding, relearning and progressivity: see bleeding, relearning and progressivity after replacement.

FAQ

Does the gearbox have to come out? No, the robot comes off on its own.

The robot has been refitted and gears jump out. First check the spacer and the tightness of the screws, then the relearn procedures.

I am refitting the same robot without changing any part. In principle, bleeding is enough; to be safe, also redo the relearn procedures.
