The 'S' in the S800 stands for 'Super' finished gears to help extend gear life. We include DCT Fluid which reduces gear smearing. These two things make this transmission your best option to allow 800lbft / 1000WHP through the OEM gears. It also includes our Carbon Clutch Seals and Billet Clutch Baskets to vastly improve the reliability and longevity of the clutch. After we upgrade your transmission, all you need to do is install it, relearn it, and hit the road. How easy was that!

OEM GR6 Gear Smearing:

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? Micro-Polishing reduces friction which will reduce the heat. On top of that we are also including our DCT fluid which is so slick and so durable that it helps to reduce gear overheating and smearing without changing clutch performance.

We handle everything for this build in-house. Please contact us if you have any questions or need assistance with shipping your transmission.

Cleaning Disclaimer <p>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.</p> <p>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. </p> <p>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 <a href="news/technical-articles/687-cleaning-equipment">state-of-the-art cleaning equipment</a> which other transmission builders and service shops could only dream of. </p> <p>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.</p> <p>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! </p> <p>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.</p>
Core Exchange <h4>CORE EXCHANGE SERVICE</h4> <p>Please <a href="mailto:%This email address is being protected from spambots. You need JavaScript enabled to view it.">EMAIL</a> 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.</p>
Optional Upgrades <h3>Flexible Trans for Future Upgrades: </h3> <p>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! </p> <p>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.</p>
Technical Info <h3>Additional Information</h3> <table width="100%"> <tbody> <tr> <td> <p>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. </p> <p style="text-align: left;"><img alt="" src="images/Product_Descriptions/SD800_Pressures_large.PNG" style="float: none;"></p> <p>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:</p> <ol> <li>Warm-Up and Relearn Pass</li> <li>Data Log Pressures vs. Target Pressures (to assure all assemblies are working properly) <a href="news/technical-articles/753-gt-r-gr6-tcm-data-logging-videos">HERE</a> </li> <li>Test drive on the street to assure proper function and 'feel'.</li> </ol> <p>You will never get a malfunctioning GR6 from us!</p> </td> </tr> </tbody> </table> <p>Please read about the rebuild process <a href="news/technical-articles/752-gtr-gr6-rebuild-process">HERE</a></p> <h4>HEAVILY WORN OR DAMAGED UNITS</h4> <p>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. </p> <h4>ATTENTION TO DETAIL</H4> <p>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 -> <a href="news/technical-articles/795-synchro-blueprinting">Synchro Blueprinting</a></p> <h4>SHIPPING</h4> <p>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. </p> <p style="text-align: left;"><img alt="" src="images/Product_Desc/DSC05481_medium.jpg" /> </p> <p> In certain situations, though, we may need ship via a freight pallet. Please <a href="mailto:%This email address is being protected from spambots. You need JavaScript enabled to view it.">email</a> or call us if you have shipping questions or for a quote. </p>
