Specs
Heavily Worn or Damaged HEAVILY WORN OR DAMAGED UNITS: 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.
Attention To Detail ATTENTION TO DETAIL: 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. Check out our article on Synchro Blueprinting which can be found under TechTips / Technical Articles
Cleaning Disclaimer CLEANING DISCLAIMER: Parts are cleaned using industrial parts washers. 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 high-end cleaning equipment which other trans 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. 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. 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! We love the older Mitsubishi transmissions and have not forgotten that it is these units which got us to where we are today. We will continue to service them as we want to continue to support the community. This is a great opportunity for the Mitsubishi enthusiast to have a build using the same high-end equipment to service the Mitsubishi transmission as we use for the expensive exotic units. This means that the cleanliness and attention to detail is unmatched! 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.
Core Exchange CORE EXCHANGE SERVICE: 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.
Micropolish Info MICROPOLISH: Micropolishing is a gentle polish on the gears that will smooth and remove some stress concentrations uniformly. It also polishes the gears in the area they make contact with other parts, so you have less friction loss which means less heat, better fuel economy, and longer life.
WPC Info 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.
Shipping Info SHIPPING: Shipping your Transmission (or complete car) to us is simple! We work with several LTL Freight and Vehicle Transport companies to offer you affordable shipping options. We will arrange all of the logistics on our end, making the process simple and stress free. Please email us for a quote!
