Performance Plus “Adamantine” T-Case Build Service – EVO 8-9. This is for ACD and NON-ACD.

This is our top dog, the boss, the big cheese, the whole enchilada, the conqueror, the destroyer, the mustard cutter; The Adamantine Transfer Case Build. This build includes absolutely everything we offer to give you the best, and strongest, Transfer Case available on the market today! We have been unable to find anyone else who will offer this extreme of a T-Case for the EVO.

This Build Services Includes:

  • New Billet (Coated & Treated) Ring and Pinion Gear Set
  • New Bearings
  • Upgraded Case Bolts (8MM to 10MM)
  • Custom Bearing Preloads
  • OEM Seals and O-Rings
  • OEM Fill / Drain Plug Washers
  • Complete Tear Down and Cleaning using state-of-the-art equipment HERE
  • ACD Clutches Modified to give you more center diff LSD action
  • Pressure Tested ACD Assembly (checks to ensure piston seals are healthy and fluids do not mix)
  • New ACD Seals - Piston and Hub (Custom Made)
  • Wavetrac LSD

We modify the pinion bearings to sit tighter and machine them to fit perfectly inside the housings without the use of the pinion shims. The pinion gear shims used by everyone are not accurate enough for the tolerances we set your ring and pinion to in this build! During high powered and shock loading applications, the shims can compress which will change the bearing preloads and gear contact. With no shims around the pinion gear, that is no longer possible.

For those of you with an ACD T-Case, we modify the clutches in the ACD assembly to give you more limited slip action! For Non-ACD owners, we test the viscous for functionality. If your VCU is out of spec, we have the ability to rebuild and bring it back to life.

Please note that if your Transfer Case is making whining noises then the ring and pinion gears are wiped out. Don't worry! This rebuild will take care of that issue! You will break everything else in your drive-train before this T-Case will have a problem.

We will also upgrade the front LSD to the best, a Wavetrac. The Wavetrac diff is the strongest unit you can buy for the EVO T-Case and is a part you will never have to worry about breaking. For you drag racers, the Wavetrac also has an added cam inside to allow for LSD action even in a straight line!

Have a rally car which breaks T-Cases every time you are air-born and slam the ground at wide-open-throttle? We have the Pikes Peak Hill Climb right here in our back yard and know what it takes to make a T-Case live under extreme conditions! We always watch people from out-of-state break their T-Cases built by a competitor. Having a cheap T-Case break is not worth it when it makes you lose the race.

Thank-you for viewing our site and considering us!

Specs

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.

We love the Mitsubishi transmission 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!

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.

Wavetrac LSD

Designed from a clean sheet using state-of-the-art knowledge and engineering to be a better differential than any other by using a patent pending design to improve grip in low traction conditions.

Wavetrac limited slip differentials give you quicker acceleration and faster cornering by driving both drive wheels instead of just one. And, they offer improved no-load performance when compared to other helical gear differentials on the market.

What Makes A Wavetrac Different?

Zero axle-load is a condition that occurs during normal driving, but creates the most noticeable problems when driving in extreme conditions. Zero or near-zero axle-load is the condition that exists when there is ‘no-load’ applied through the drivetrain, when one drive wheel is nearly or completely lifted (often in aggressive cornering). It also occurs during the transition from engine driving a vehicle to engine braking and back, even with both drive wheels firmly on the ground.

Here’s how that loss of drive hurts you:

  • If you lift a wheel, all gear diffs except Wavetrac®, will NOT power the other wheel.
  • During the transition from accel to decel, all gear diffs except Wavetrac®, do nothing.

Why does this happen?

All gear LSDs (including Torsen®, Truetrac®, Quaife®, Peloquin, OBX, etc.) work in basically the same manner: they divide the drive torque between the two axles, applying drive to each side, up to the available grip of each tire. The amount of drive torque one wheel can get over the other is described as the bias ratio, a measure of the torque split across the axle.

Standard, open differentials have a bias ratio of 1:1. They can only apply as much drive torque as there is available traction at one wheel. When one wheel loses grip, the total available drive is lost as well (at a 1:1 ratio). All your power goes out the slipping wheel - along the path of least resistance.

Torque biasing differentials offer increased bias ratios over open differentials. For example, if a diff has a bias ratio of 2.5:1, then it can apply drive torque to the wheel with the most traction (gripping wheel) at 2.5 times the traction limit of the wheel with the least traction (slipping wheel). This is a significant improvement over an open diff… most of the time.

The problem is that when one tire has LITTLE or NO grip (zero axle-load), the other wheel gets ZERO DRIVE, because (basic math here): 2.5 x 0 = 0.

Lift a wheel (or substantially unload a wheel) and you get zero axle-load on that side - that means that during the time the wheel is unloaded, the typical diff will NOT power the wheel that’s still on the ground. No matter how high the bias ratio, you get no power to the ground.

During the transition from accel to decel, where you have near zero torque on the axle, even if the wheels are on the ground, the typical diff is unable to begin applying drive torque until AFTER the zero torque condition is over. While this condition is generally short-lived, the fact that most diffs can do nothing during that time means that there will be a delay once the zero torque condition stops - creating a reaction time in the driveline.

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

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

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.
