Subaru Impreza WRX STI Gearbox/Transmissions Repairs, Rebuild, Service and Sales in Australia

Standard equipment

The STI is the tougher, meaner and faster version of the WRX. From 2002, every STI boasts the strongest transmission available in the Subaru range as standard! The 6-speed manual gearbox is one of the best in the business and has been instrumental in securing Subaru a large number of podium finishes in track and rally events, including 10 consecutive wins in Australian rally and 6 world rally championships! Although the 6 speed STI is extremely durable, damage and breaks can still occur. All drive Subaroo has reconditioned more 6 speed STI units than any other Subaru specialist in the country. If you want to upgrade your STI 6 speed, All Drive Subaroo offers 6 speed units that are rated at over 550KW! Perfect for track, drag or just daily use, these gearboxes are available in complete conversion kits built by All Drive Subaroo.
Being the most sought after transmission for Subaru models, All Drive Subaroo has developed a direct fit conversion that can be easily installed into all EJ models, and most other Subaru models.
All drive Subaroo has the largest range of remanufactured 6 speed STI gearboxes and new parts to suit any 6 speed repair.
The 6 speed STI transmission has no known weaknesses. At high mileage sliders and synchros wear, but the gears seem to last virtually forever. For whatever might go wrong, we offer either repairs using selected used or new OEM parts, or replacement gearboxes built to suit your budget. For peace of mind an industry-best warranty is offered with each build level.
All drive Subaroo also offers sequential shifters on our 6 Speed STI range.
All the benefits of a sequential gearbox without the $25,000 price tag.
All drive Subaroo has a gearbox team dedicated to researching and developing new ways to make the 6 speed STI gearbox stronger and better! Our 6 speed STI conversions feature 4kg couplings as standard, as well as 12kg and 20kg viscous coupling unit upgrades.
