Mitsubishi Evolution X SST Gearbox Repairs and Upgrades

Mitsubishi Evolution X SST Gearbox Repairs and Upgrades

In 2008 Mitsubishi released the final chapter of the Evolution brand, the Evolution X.  For the first time, the Lancer Evolution was supplied with the option of a 6-speed, semi-automatic SST Gearbox. The Getrag transmission found in the Evolution X is a very complex piece of engineering, which we believe requires more frequent maintenance than recommended by Mitsubishi. Repairs and Upgrades to these units are one of the most common concerns undertaken on the Evolution X and if you were to visit a Mitsubihi dealer, they would suggest a new transmission should you encounter a issue.

Service Maintenance

We at Auto Torque are pleased to offer comprehensive services to overcome any faults you may have with your SST transmission but it is vitally important to maintain your Evo X to a high standard and regularly replenish the SST fluid with genuine Mitsubishi Diaqueen SSTF. We only use genuine filters and oil in our work on SST transmissions, the use of non genuine fluid will bring mechatronic and clutch issues.

Shift Forks

Our tried and tested repair to SST shift forks will restore the shifting of your SST gearbox and ensure reliability for the future. An upgraded compound is applied to the fork, to restore the position of the magnets and we supply a lifetime warranty with all shift fork repairs.

Clutch Packs

We are an authorised UK dealer for Dodson Motorsport parts allowing us to offer uprated clutch packs to suit 450ft/lb to 600ft/lb upgrades.

Clutch Damper

Replacement of the clutch damper can solve issues including harsh gear change, clunky first gear and certain fault codes.

Mechatronic Assembly

We are pleased to offer various solutions to restore the operation of your SST Mechatronic assembly. Upgraded bore plugs to prevent leakage and maintain consistent oil pressure, this can lead to gear selection and clutch slip issues.

Fault Codes

We use a Mitsubishi MUT III diagnostic tool for fast and accurate diagnosis of all fault codes, programming and performing complete re-learning of the SST gearbox.
