Subaru 6 Speed Gearbox

6 Speed STI - RepairTo successfully rebuild, or overhaul the sandwich plate type 6 speed manual gearbox as found in post 2000 model Subaru WRX STi and some 2.5lt turbo and 3.0lt Liberty N/A manual transmission models, it is necessary to use many special service tools for alignment of internal parts that cannot be seen once the gearbox housing has been installed. Failing to do so will cause gear balking, premature wear to synchro-cones, shift fork failure, abnormal gear noises and jumping out of gear.

A wide range of spare parts are also required to correct values which fall out of specification after replacing any internal parts to ensure proper gearbox operation.

Subaroo Gearboxes has a complete range of Subaru 6 speed parts in stock to correctly service and carry out repairs to these transmissions.

Buying 2nd hand Subaru gearboxes can be risky business.



Wrecking yards will tell you that the Subaru gearbox they have has done less than 70,000kms.

Would you buy the gearbox if they tell you its done 140,000kms? Are they likely to tell you that?

All Subaru 5 speed gearboxes look the same side by side, yet there are many differences internally from model to model that can cause drivability and reliability concerns and even serious injury to you and your passengers if you are given the incorrect gearbox for your vehicle.

There is no way to determine the condition of a 2nd hand Subaru gearbox unless the gearbox is totally dismantled and thoroughly inspected prior to using it.

The one you know maybe better than the one you don't know!

Applicable for all 5 speed manual Subaru gearbox models
