EVO X Performance Trans Build Service Includes:
The EVO X 5-speed has to be one of the most beautifully engineered transmissions we have seen in a Mitsubishi. The large triple synchro 1st and 2nd to the double synchro 3rd, 4th and 5th make these very strong and a joy to drive! Please read our review of the EVO X transmission HERE.
Unfortunately, the unit will need to be serviced if raced, abused or neglected. There are also issues with the center diff pins, shift fork pins and the 3-4 fork that might creep up to bite you as well.

Jacks Transmissions has grown into a company which now services exotic and terribly complex DCT (dual clutch transmissions) used in the GTR, SST, Porsche, Audi, VW, and many more high end vehicles. 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. We have also designed and built many of our own parts for these vehicles.
All machine work, cleaning, and detail work is performed in-house by very talented technicians and engineers. The quality you get from Jacks Transmissions is an unbelievable bargain. We do not know of anyone else who cleans the transmission via a 110gal Ultrasonic and Pulse-Jet unit, or who employs such talented people.
Exceptionally clean units are one of the many reasons why our Transmissions and Transfer Case assemblies are of the highest quality in the business! We have state-of-the-art cleaning equipment which other transmission builders and service shops could only dream of.
With the best cleaning equipment, we also have a very clean facility. All units are built in a spotless environment 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 transmission 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 does not happen here.
The quality and experience you get from Jacks Transmissions shows with the overwhelming number of high-end vehicles we service in our shop. Be a part of the rare opportunity to have one of the cleanest and most experienced specialty shops in the World service your transmission!
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 build services and you will see the additional attention we provide which is unique and cannot be duplicated.
We love the Mitsubishi transmission and have not forgotten that it is 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 transmission as we use for the expensive exotic units. This means that the cleanliness and attention to detail is unmatched!
CORE EXCHANGE SERVICE
Please EMAIL us for price and availability. Many of the build services we offer can be performed on an 'exchange' basis. Core charges and core convenience fees are separate from the costs of the build service. In many cases, core fees can be refunded pending the condition of what we receive in exchange. Note: We will retain a 10% convenience for this service.
WPC GEAR TREATMENT
WPC is a permanent surface treatment that reduces friction while strengthening the part. Its unique micro-dimple formation pattern greatly reduces friction and is unmatched by conventional methods of surface treatment. It is a proven process that has been utilized for many years in the racing and automotive industry and is complimented by utilizing our Micropolish treatment. WPC can strengthen parts in two ways. First it adds an extremely high level of compressive stress at, and near, the surface. The second, is that the WPC treatment creates a Nano - Crystalline structure at the surface of the metal. Both of these mean that metal fatigue and crack initiation are both noticeably reduced; thus strengthening the gears and shafts inside of the transmission.
Micropolishing is a gentle polish on the gears that will smooth and remove some stress concentrations uniformly. It also polishes the gears in the area they make contact with other parts, so you have less friction loss which means less heat, better fuel economy, and longer life.

Center diff pins are modified so they do not back out and go through your case. OEM on the LEFT, modified on the RIGHT. Not the most elegant looking, but very effective. This is a very time consuming process which only we perform in-house:
Center Diff Pin Failures
Most people are only replacing the pins when repairing/upgrading your EVO X center diff. This will not work! The reason the diff pins fail is due to a lubrication issue. The gears do not receive enough oil, so they seize to the shafts which break the pins as the twisting force applied to the pins is more than they can eventually take. The seized gear will twist the locking pin right off the shaft. Upgraded pins will delay the failure of the shafts working their way through your case, which is fine for most builders as it will live through their warranty, but WILL NOT solve the lubrication issue. What we do is tear the whole center diff down. We modify the shafts to allow for more oil, we upgrade the pins for added insurance, and we then add scoops to the center diff housing to force more oil inside the assembly. The way the assembly is designed is flawed in that the faster you drive your car the less oil is able to get inside. Our scoops will force more oil in the assembly. If that was not enough, there's more! We also modify the sun gear pins so they can float in the housing. This modification, along with the scoops, is the major difference between our Center Diff Upgrade and everyone else. Have the peace of mind that your diff will live forever with our modifications and never give you an issue again! We offer a lifetime warranty against center diff failure due to how well our modification works! Ask any of our competitors if they would give you a lifetime warranty on your center diff, we believe the answer to be 'NO'.
Please email us for any questions you may have.
HEAVILY WORN OR DAMAGED UNITS
Any additional parts needed which are not listed or not part of this build will cost extra to replace. We will email pictures and detailed information if this is the case. We know you do not like surprises, so we try to make this process as painless as possible. If this turns out to be the case, though, please keep in mind that we just want you to have a high quality built assembly. Having your vehicle down is bad enough, so why cut corners and risk it again? Quality is the key here and sometimes it costs more to do this on a specialty or aging platform. Simply put, it is not worth the risk of using a sub-par component if an inspection reveals it is a weak link.
ATTENTION TO DETAIL
All machine work and cleaning is performed in-house. We also spend a lot of time on synchro timing, alignment and operation to give you the best shift possible. Click -> Synchro Blueprinting
