Mitsubishi SST Mechatronic System

Mitsubishi SST Mechatronic Repair

The Mitsubishi Twin Clutch SST (sport or sportronic shift transmission) is the name given to the dual clutch 6-speed transmission designed by Getrag for Mitsubishi Motors. As with other rival systems, the SST transmission is controlled by a transmission ECU (Mechatronic Gearbox ECU), sensors, solenoids and valves – all housed within the transmission valve body and it is extremely common for these parts to become faulty.

Common Mitsubishi SST Mechatronic Problems

Some of the most common faults associated with the Mitsubishi SST Transmission are listed below:

  • Power loss
  • Jerking in/out of gears
  • Gearbox fails when it overheats
  • Not going in to gear
  • Loss of reverse gear
  • Limp Mode

If you have any of the above faults and your vehicle has been diagnose with a faulty SST Mechatronic unit then you may have been advised that the unit is not a repairable part and once a fault has developed it must be replaced – this is not entirely true. Mitsubishi dealerships do not have the required extensive knowledge and equipment to test and repair a part, if the part is faulty they will replace it and the cost of replacing a mechatronic unit is upwards of £1200.00 +Vat.

My Mitsubishi SST Has a Mechatronic TCM Fault – Can SINSPEED Help Me?

At Sinspeed we have the latest state of the art mechatronic testing and repair facilities that allow us to fully test even the most intricate system types in an isolated environment. We use genuine OEM components when rebuilding a mechatronic unit but also uprate parts where possible to strengthen the repair and eliminate common known weaknesses. All remanufactured mechatronic units are set up to be plug & play when refitted back to the vehicle, with no additional programming/coding required.

All repaired mechatronic units are returned with a Lifetime warranty. For more information on our testing and repair services, please call us on 0844 847 9999.
