3S Dog Box Trans Build Service Includes:
This transmission build service is recommended for the 3S enthusiast wanting THE ultimate gearbox. This Dog Box uses racing gear-engagement style dog teeth instead of conventional synchros, which allow for quick and definite gear shifts. This transmission can easily be driving on the street as well as abused on the track! The gears that are equipped with the dog teeth are 1st thru 4th only. The 5th / 6th / Reverse gears use the stock synchros.
The 1st gear has straight cut teeth. The 2nd gear has a reduced helical teeth. The 3rd and 4tf gears are stock. Unlike most racing Dog Box transmissions, this transmission is absolutely silent in all gears except the 1st. First gear does not whine, but it sounds pleasantly entertaining. The gear box uses the original H-pattern shifting mechanism making this transmission is absolutely streetable.
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.
Want to push your transmission even further? Consider upgrading your Front Diff to a Quaife LSD (includes new bearings) or changing out your aging Viscous Coupling / Center Differential assembly with a Torsen Center LSD and 300M Output Shaft. We are also offering WPC treatments to the transmission internals!
The SCE Torque Biasing Center differential enables your car to accelerate quicker and corner faster. How? By reducing the understeer and by sending the power to the wheels that could use it! Combine this with the Quaife, and never worry about having a diff failure!
WPC GEAR TREATMENT
WPC is a permanent surface treatment that reduces friction while strengthening the part. Its unique micro-dimple formation pattern greatly reduces friction and is unmatched by conventional methods of surface treatment. It is a proven process that has been utilized for many years in the racing and automotive industry and is complimented by utilizing our Micropolish treatment. WPC can strengthen parts in two ways. First it adds an extremely high level of compressive stress at, and near, the surface. The second, is that the WPC treatment creates a Nano - Crystalline structure at the surface of the metal. Both of these mean that metal fatigue and crack initiation are both noticeably reduced; thus strengthening the gears and shafts inside of the transmission.
