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.
This is a long overdue review.In short, these guys are the most trustworthy, professional individuals I have dealt with when it comes to car repair.I brought in a manual Cadillac CTS that was in need of some clutch work. They sourced the parts and when the flywheel they installed did not work, they immediately ordered another one and replaced it at no costA few weeks later, the car developed other issues that I thought were clutch related and when they took a look at it, they alerted me that my new problems had nothing to do with the clutch and gave me some much needed advise on what to do next.Great business, great people. Worth the money.
HIGHLY RECOMMENDED Expert Transmission Service at this service centre. I had been referred to Mr. transmission in Whitby701 Brock Str N. by another service centre in the area, in 2019. They diagnosed our issue with transmission cooler leaking fluid built inside the engine radiator. They made recommendations to us for flushing the lines.Just recently my other vehicle development transmission shifting issues. After doing a computer diagnostics and engine light illumination test (@ no charge) the team of technicians determined that my issue was NOT an issue with the transmission but rather my alternator stopped charging and was causing shifting issues due to no power supply provided for the transmission. They recommended to have repairs done at another local business for the replacement of the alternator and then return for a NO Charge diagnostics check of the transmission to verify the issue has cleared. They confirmed that the transmission is working as expected after the alternator repair and no repairs were required for the transmission. That is amazing service and i couldn't ask for anything more. You earned my Trust Mr. Transmission. Thanks.I decided while I'm there that I would have my 1st hydraulic fluid and filter change done. it was recommended to come back after 10 days to check the transmission is performing as expected. That diagnostics testing confirmed again, all is well. The service technician, the management team and the service at the front counter was supreme!Key take away from Mr. Transmission is Honest assessment, the correct work is done in the time estimated and done with satisfaction and as estimated in cost.I have already made referrals to you and I found myself a business I will come back to!Thank you Denise and the entire Team of service technicians! Keep up the great work!
Extremely professional and welcoming, Denise at the front desk was a pleasure to deal with. Sean and the guys in the shop were efficient and did great work, I highly recommend these guys if you live in the Durham region.
Been here a couple times with a couple different vehicles. Fair price for the work needed, and the work is completed quickly. Knowledgeable and professional staff. Very honest about the severity and urgency of the issue, didn't try to make it seem like a bigger deal than it was.Very refreshing for this industry! Overall excellent experience and I highly recommend the Mister Transmission in Whitby!
