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

Additional parts / services may be required, depending on the condition of your transmission.

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.

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.  More info HERE

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. 

Your unit is also shipped in a double walled custom made box for Jacks Transmissions.  Your unit will be sitting snugly, and safely, in preformed foam pads to assure trouble free delivery.



Thanks to the Mitsubishi Community!

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!
