A clean and healthy main valve body is important for proper operation and long life of the GR6. We tear the valve body down, clean all 7 filters inside, check and clean the shift pistons, and replace the two solenoids. The shift pistons are what move the forks and engage the synchros and gears. In time, if the TSB clip update has not been performed, the piston can rotate and lock into the end of the fork, causing it to bind and eventually break. We install our TSB clips in all main valve bodies which have not had this service performed in the past. This binding can also lead to scratches and gouging on the piston surface, and we can refresh those areas as for smooth operation, too.
The two Axis Solenoids are responsible for the distribution of pressure in the valve body to allow for shift selection and clutch operation. These are the two solenoids that most frequently fail and are replaced with revised / updated OEM components in every rebuild.
The valve body is tested at a component level at the bench, and if any other parts are required we can also supply them to bring the unit back to operational.

| 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> |
