This transmission rebuild is recommended for 90-99 AWD DSM’s (Talon, Eclipse, Laser) at near-stock power levels. This build package was designed to fix the most common causes of poor quality shifting, while correcting several key areas to increase reliability.


Parts cleaned using industrial parts washers. 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 trans 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.

Jacks Transmissions has grown into a company which now services exotic and terribly complex DCT (dual clutch transmissions) used in the GTR, SST, Porsche PDK, 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. 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.

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!

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!

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.


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 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.

Additional Information

1-2 Shift Fork combined with our efficient double synchro makes for a very strong and reliable assembly. You will never have to worry about a broken 1-2 fork again.

Unbreakable 3-4 Shift Fork Upgrade - 1G

3-4 Shift Fork - 2G

All Bronze Synchronizer Blocker Rings (Excludes early 90 style 5th)

Jacks Trans machined double synchro 2nd gear upgrade, with removed lip, to allow for longer synchro life. Please note that this gear is NOT the same as the double synchro 2nd found in the 2G. Our gear is designed with more room for synchro wear and a more precise fit.

1-2 Synchronizer Hub
1-2 Synchronizer Slider

1-2 Synchronizer Springs (x4)
3-4 Synchronizer Springs (x2)

1-2 Synchronizer Shoes
3-4 Synchronizer Shoes

5th Gear Synchronizer Blocker Ring with Flipped Slider (Excludes early 90 style)

Input, Output, and Axle Seals

Tapered roller bearings on each end of intermediate shaft. It is becoming more common, now that these units are aging, to see intermediate bearing failures. We replace them in every rebuild to assure reliability.

1-2, 3-4, and 5-R Roll Pins

Center diff spider gear side shims x2

Upper Torrington upgrade. This is important as the thrust washer included from the factory fails often and can damage many parts in the trans. This eliminates that issue.

Drain Plug / Fill Plug Washers

Neodymium Trash Magnet

We reset bearing preloads to our specs for maximum bearing and gear life.


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.


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


Shipping your Transmission (or complete car) to us is simple! Most assemblies are shipped in a double walled custom made box. Your assembly will be sitting snugly, and safely, in preformed foam pads to assure safe delivery.

In certain situations, though, we may need ship via a freight pallet. Please email or call us if you have shipping questions or for a quote.
