Rebuilt to shift better than new, last longer, and handle more power, Jack's Transmission offers the reliability you need to handle the performance you want!

Our EVO 5-speed transmission rebuilds include all Mitsubishi Technical Service Bulletins. We also include some other little touches to the synchronizer assemblies that we have learned through years of experience with the DSM units to make your EVO unit shift better than when it was new!We spend a lot of time on synchrotiming, alignment andoperation to give you the best shift possible.

We have also found a way to change a few things during assembly to not only reduce, but eliminate gear-to-hub thrust wear. We have our own preload specifications which will make your gears last longer and handle more power.

This trans is used by the fastest EVOs in Colorado. Many with multiple 10 second passes here at 6000ft with no issues at all and they are street and track driven cars! A couple have had our trans untouched since 06.

For a t-case that can also handle this power check out our t-case rebuilds too!


The EVOX 5-speed has to be one of the most beautifully engineered transmissions we have ever 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!

Unfortunately the unit will need to be serviced if raced, abused or neglected. There are also issues with the center diff pins, fork pins and 3-4 fork that might creep up to bite you as well.

Have a 3rd gear crunch? No problem, we know how to change the slider ramp rate to fix that problem and we do it on all of our rebuilds!

The rebuild we offer for the EVOX include our fix to the center diff pin issue, fix for the fork roller pin problems, and 3-4 fork wear so you never have to worry about it again. Our units come with the longest warranty in the business which is unlimited mileage 14 months!

Shipping will be determined at the time of purchase on this item due to size and weight.

Do you guys rebuilt transmission for Evo 8 MR 6 gear?

Asked by: Rangel805
Shep Transmission will do a "back-to-stock" rebuild on the 6 speed, but they do not have a "performance upgrade" available.

I would like to ask if this can be modify to have a 6th gear.. How much would it cost if ever.. Thanks and more power

Asked by: Skykid
This particular transmission could not be modified to have a 6th gear, but the Evo MR's were available with a 6 speed and you could source one from one of those.

how munch horse power can it handle

Asked by: jwoajorge
This service consists primarily of upgrades and/or replacement of the synchros, sliders, and bearings to refresh worn components and improve shifting. While it is mentioned a few times in the description that it will hold more power than a stock transmission, this is accomplished only by tweaking clearances during assembly to reduce wear. As such, there are several factors that will determine the longevity of this transmission including power output and driving style. As outlined they have had several customers running 10s in the quarter mile with this product, but putting a finite hp rating on this product is quite difficult.

Asked by: Halvring91
You would send your Evo transmission in for a rebuild and receive it back when it is done. This is a service offered by Jacks Transmission through MAPerformance.

How long does the turn around take?

Asked by: Richy970
Jacks transmission rebuilds typically take between 4-6 weeks depending on race/project season. Busy times typically take longer due to the sheer volume of rebuild projects Jacks see's, but you can expect the same quality rebuilds year round.

Do you have a exchange program where you ship me a trans and i pay a deposit and the deposit is refunded when you get my old unit? The reason I say this, 6 weeks is a long time for my car to sit in someones shop waiting for a trans it is a storage issue.

Asked by: fasttgt6
At this point in time, Jacks does not offer a core program. Because of this, the wait times vary based on the time of the season. 6 weeks is the maximum time as quoted by Jacks. It could very well take less time.

On your 1st gear strech what happens to second gear now a longer first  means a short second am i right on this. how about a longer 2nd instead of first.

Asked by: fasttgt6
The Evo 9 1st gear is 2.785:1 which equates to a 4.88% mph increase over the 2.928:1 Evo 8 1st gear. The 2nd gear is the same for both the 8 and 9, leaving plenty of room for acceleration. A taller 1st gear in no way impacts the ratio of the 2nd gear.
