Stage 2 - EVO III 3-4 Upgrade


We will need your gear clusters for rebuild. This build includes changing your gears to EVO III 3rd - 4th, which are double synchro. This makes for a nice reliable 450-600HP gear set!  Please simply EMAIL US if there are additional parts which you require. Note: If your current gear set is an early style (90-91), it will require a different style center diff. These are available for an additional charge

This cluster build also includes New 3-4 Shift Fork and New 3-4 Shift Rail.

Note: If you do not have clusters to send to us for this build, please contact us before hand to see if we have a good/used OEM 1st gear set available.

Parts cleaned using industrial parts washers.  Exceptionally clean units is one of the reasons why our transmissions are the highest quality in the business!  We have state-of-the-art cleaning equipment which other trans builders could only dream of.

With the best cleaning equipment, we also have a very clean facility.  All units are built in a spotless environment and using tools, and benches, which are clean and only used for assembly purposes.  In other words, the same tools used to pull your dirty old trans out of your car are NOT the same tools used to rebuild your pristine unit afterward. Take a look at the typical shop and check their tools.  It is shocking how dirty things are in most shops and that dirt will end up in your unit.  That doesn't happen here.

Thanks to the Mitsubishi Community!

Jacks Transmissions has grown into a company which now services exotic and terribly complex DCT (dual clutch transmissions) used in the GT-R, SST, Porsche PDK, Audi, WV, and many more high end vehicles including the Lambo robotic E-gear.  Due to this exciting change, we have spent a lot of money for the state-of-the-art equipment needed to service these high dollar and expensive units you find in $100k+ vehicles. We have designed and built many of our own parts for these vehicles.

We love the Mitsubishi trans and have not forgotten that it's these units which got us to where we are today.  We will continue to service them as we want to continue to support the community.  This is a great opportunity for the Mitsubishi enthusiast to have a build using the same high-end equipment to service the Mitsubishi trans as we use for the expensive exotic units.  This means that the cleanliness and attention to detail is unmatched! 

All machine work, cleaning and detail work is performed in-house by very talented technicians and engineers.  The quality you get from Jacks Trans at the price we have listed is an unbelievable bargain.  We do not know of anyone else which cleans the trans via a 110gal ultrasonic and Pulse-Jet unit, or employs such talented and expensive people.

The quality and experience you get from Jacks Trans shows with the overwhelming number of high-end vehicles we now service at the shop.  Be a part of the rare opportunity to have one of the cleanest and most experienced shops in the World service your trans! 

Our pricing structure was created to assure only the highest quality materials and workmanship.  Anyone which beats our price is taking short-cuts which you will pay for in the end.  Look into the details of our rebuilds and you will see the additional attention we provide which is unique and can't be duplicated.  We would be honored to keep the EVO tradition alive and service your trans!
