S800 Build Service Includes:

The 'S' in the S800 stands for 'Super', as in 'Super' finished gears and our 'Super' amazing fluid! It is just ‘Super’ all around. We also include our proprietary DCT Fluid which eliminates gear smearing! This transmission is your best shot to allow the gears to live and handle up to 800 torque / 1000WHP under $7k. Oh, and it also includes our amazing Carbon Clutch Seals and Extended Spline Billet Clutch Baskets!! All you have to do is install, relearn and you're done. How easy is that???

The S800 is the highest quality OEM 2-6 geared transmission we have ever offered. We believe in this trans so much that we are offering a crazy 1 year bumper-to-bumper warranty on the COMPLETE transmission! If that's not enough, this unit is also easy to upgrade making it the most flexible transmissions on the market! Future clutch and gear upgrades are cost effective and easy with this trans.

This transmission service truly is an engineering marvel and is an incredible deal for what you get. There is nothing else on the market in this price range which includes so much detail and upgraded parts. Take a look at the list of parts and compare to other’s builds equivalent to ours. You pay extra for the fluid, upgraded seals, synchro sleeves, ETS rebuild, etc. That adds up quickly, but it is all included with build service to make this an easy process (and an easy choice)!

What is the big deal about the OEM 2-6 getting polished and our new fluid?? The OEM 2-6 gears are very strong, but they have an overheating problem. The heat starts at the root of the tooth and the gear begins to 'smear' from the root out. As you stress the gear repeatedly this process will weaken the gear and it will break. The solution is obviously to keep the gear cool, but super slick fluid will make your clutches slip, so how do you deal with that? Micropolishing reduces friction which will reduce the heat. On top of that we are also including our amazing DCT fluid which is so slick and so durable that it eliminates the gear overheating and smearing completely without changing clutch performance! Yes, we didn't believe it either but ran this fluid through the ringer and it truly works! This sets the OEM 2-6 up to live under the most extreme conditions that would have killed them in the past.

We handle everything for this build in-house. Shipping your trans is simple, please contact us for help.


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.


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.

Flexible Trans for Future Upgrades:

This S800 includes our extended spline billet clutch baskets. This means you never have to worry about baskets again! If you choose to make more power and need a bigger clutch in the future, these baskets can support the addition of many more plates to go as high as 1300ft/lb torque capability! The extended splines add the real estate needed for big clutch capability!

On the gear side, this trans allows you to upgrade to an Albins or PPG 2-6 at any time. The easier it is to upgrade the more cost effective it becomes.

Additional Information

We make it easy! This transmission ships filled and fully tested! Yes, you read that right and we are the only company to perform this service.

We install, test and run each GR6 before it leaves our facility. We have 2 test-mule GTRs here purely for this purpose. The tests performed are:

  1. Warm-Up and Relearn Pass
  2. Data Log Pressures vs. Target Pressures (to assure all assemblies are working properly) HERE
  3. Test drive on the street to assure proper function and 'feel'.

You will never get a malfunctioning GR6 from us!

Please read about the rebuild process HERE


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.
