Pinpointing the exact cause of any transmission problem takes skill, knowledge, and investigation
The evolution of transmissions has made these machines and systems increasingly complex. When transmission repairs are required, determining the cause and cure for what ails can be tricky. Why? Because transmissions have become remarkably complex and computerized and that presents both advantages and disadvantages. On one hand, transmission performance has become noticeably better in all vehicle makes and models. On the other, the increased complexity and digitization of transmission systems has made repair work a highly technical and complicated affair.
As you can imagine, there are different types of transmission repair jobs and options you can choose from depending on the nature of your vehicle’s breakdown. Understanding what those options are can help you make informed decisions when faced with a choice of transmission repairs to weigh.
A Repair for Every Type of Transmission Malfunction
Some transmission repair work is straightforward and mechanical in nature. Other times, it’s a combination of mechanical and electronic engineering that’s required to get your car back on the road. The most common types of repair work include:
- Adjustments and in-car repairs. Most minor repairs are simple matters that are done without removing the transmission from the vehicle. If yours is a computer-controlled transmission that is not shifting properly, it is often the result of a computer sending incorrect signals due to a faulty sensor, or the transmission is not reacting to the command because of a bad connection or defective solenoid pack. If a non-computer controlled transmission is shifting too early or too late, it may require an adjustment to the throttle cable. If the vehicle has a vacuum modulator instead of a throttle cable, there is an adjustment that can be made using an adjustment screw in some designs. In vehicles with modulators, however, it is important to ensure there are no vacuum leaks and that the engine is running at peak efficiency.
- Reseal jobs. A transmission is re-sealed to repair external transmission fluid leaks. If you see spots of red oil on the ground under the car, your transmission may need a re-seal job. To check a transmission for leaks, a technician will put the vehicle on a lift and examine the unit for signs of oil leaks. If a leak is spotted at any of the external seals or gaskets and the transmission otherwise performs well, the technician will most likely recommend that the transmission be re-sealed. Most of the external seals can be replaced while the transmission is still in the car but, if the front seal must be replaced, the transmission must first be removed from the vehicle to gain access to it.
- Replacing accessible parts. There are a number of parts that are accessible without requiring the removal of the complete transmission. The parts that are accessible, however, vary from transmission to transmission and most transmission repair facilities would hesitate to provide meaningful warranties on external repairs for the simple reason that they cannot see if there are any additional internal problems in the components that are only accessible by transmission removal.
- Complete overhauls. Also known as “rebuilding a transmission”, a complete overhaul involves the removal and disassembly of the transmission in its entirety. Every part is inspected for wear and damage, then cleaned in a special cleaning solution, or replaced with another part depending on its condition. Parts that have friction surfaces, such as bands and clutches are replaced as are all seals and gaskets. The torque converter is also replaced, usually with a remanufactured one. Technical service bulletins are checked to see if the auto manufacturer recommends any modifications to correct design defects that were discovered after the transmission was built. Automobile manufacturers often make upgrade kits available to transmission shops to resolve these design defects.
Replacing or Overhauling a Transmission
When a transmission requires an overhaul, there are two options that you may have. The first is to remove your existing transmission and overhaul it, then put the rebuilt unit back in your car. The second option is to replace your existing unit with another unit that has already been rebuilt or remanufactured.
A word to the wise: replacing your transmission with a used one may not be your best option. Used transmissions often have questionable histories that could create a whole new set of challenges. New transmissions, meanwhile, are mostly aftermarket transmissions billed as new but are in fact rebuilt transmissions with new parts.
The cost of the repair is always top-of-mind and understandably so. Transmission repairs are usually unexpected (and unwelcome). The cost varies depending on the outcome of our diagnostic testing, and we will help you to understand the various factors that come into play. We also offer our customers flexible payment options.
Whichever route you choose, you can trust our transmission experts to get you and your car back on the road.

What Customers Say About Mister Transmission
Service good. Took a week before vehicle was ready then i paid the big bill drove off and noticed there were still problems with transmission. Returned next day so they could solve the technicalities but now its good. Took over a week total before the van is runnning smooth again.
Excellent service, always kept me in the loop with what was going on with the repair
This company is the top of the line. The owner went out of his way to make sure I would get the best value for the necessary repairs. He checked out several options for me to make a choice on what repairs were urgent and what could wait. He made sure everything was within warranty and on budget.
great service and they were willingly helpful
Mr. Transmission was a saviour that day. My transmission went as I was returning from Richmond to Surrey. I was literally coasting over the Patullo hope to not be THAT person stalled on the bridge. Fortunately we made it over and safety into a gas station parking lot. BCAA wasn't able to come until 2:30. I called my Kal Tire, regular mechanics, who informed me that they would be sending up the road to the Mr. Transmission and why not call directly. They gave me the number, I called and spoke with Nav. Generally they close at 1 on a Saturday. When I told him BCAA couldn't come until 2:30 he offered to come back from home to meet me. It all worked perfectly for the meet. My car was repaired and returned to me. It was still running a bit roughly so I drove it to give the computer more information. Took it back to Nav and his techs to review. Nav dropped me back home. He then came back with car, after review, so that I could attend to a family emergency. When I was able to return the car for the followup to the adjustment they once again gave me a ride home, thoroughly reviewed the transmission and delivered it back to me. I can't say enough about the service I have received at this Mr. T. I support local business and mutual respectful relationships between them.
They know me by name and are very good at making sure my cars are safe to drive
