Differential car in disassembled condit


Other Services We Provide

While transmissions are our specialty, we offer full mechanical service of all driveline components from the flywheel to your brakes. Our OE level scan tools and reflashing capabilities mean that we aren't reliant on dealerships to finish our work.


We have extensive experience diagnosing and repairing four wheel and all wheel drive systems.  We overhaul most transfer cases in house with the same emphasis on quality that goes into our transmission rebuilds.


The machine work that accompanies our differential overhauls really sets them apart.  New ring gears are heat treated after being machined, which means that the mating surface with the differential carrier is always warped.  This warpage distorts the carrier as well, and when a new ring and pinion are bolted on, leads to wide variations in the distance between the teeth of the ring and pinion (lash).

We surface grind the back of the ring and turn the carrier true with it's bearing pilots.


Virtually every transmission produced since the early 1990's has been computer controlled, and as time has gone bye, the controls and on board electrical systems on modern clutch-to-clutch shifted transmissions today are as different from those early systems as the early systems were from vacuum modulators.  We've been here for all of it and we've been keeping up all along.  We have factory diagnostic tool capabilities on hand for GM, Ford, Chrysler, Toyota, Volvo, and Honda vehicles.  We also have OE level tools available for many other makes including Nissan, Kia, Hyundai, and Volkswagen.

Most shops and dealerships do all diagnosis on a "flat rate" basis.  In a flat rate system, the customer (or car company) is billed a preset amount of time for a diagnosis or repair, regardless of how long it actually takes to complete the work.  In most dealerships, the technicians are actually paid by the amount of billable flat-rate hours they logged, not by the amount of time they actually spent working.  No car company will pay more than 45 minutes for electrical diagnosis, even though it often takes that long just to disassemble enough of the car to access the circuits you need to test.  Theoretically, this system could benefit the customer in some diagnostic scenarios, as this policy creates a scenario where if your issue cannot be diagnosed in less than thirty minutes, the technician working on your car is essentially paying for it.  The reality that too often comes to pass is that in order to avoid a lengthy diagnosis, the technician will simply replace what they feel is the most likely issue.  This allows them to collect the 45 minutes of diagnosis and whatever time they can collect by beating flat rate on the repair they just sold.  If this doesn't fix the issue, they simply start back over with a fresh 45 minutes of diagnosis and move on to the next most likely part.

We don't do diagnosis this way.  When you bring your vehicle in for your initial road test, we'll discuss the issue with you and ask you approve an amount of time dependant on the estimated difficulty of the diagnosis.  The time you're asked to approve is a cap, not a minimum.  If we ask you for three hours and find the issue in a half hour, you only owe for a half hour.  Once the vehicle has a complete diagnosis, if the vehicle requires parts, we will contact you with an estimate to actually repair the vehicle.  If the problem is damaged wiring, we usually try to quote enough time to be able to repair the wiring inside of the original diagnosis quote.
