Transmission Maintenance & Service in Port Union, ON

Keep your car on the road with preventative transmission maintenance

Just as you have other parts of your car serviced, your transmission needs maintenance to ensure a long life and avoid transmission problems. Our transmission service consists of a complete diagnosis of your transmission’s performance and general operation. Several of these procedures will be performed twice; once by the centre manager, and then again by a technician. This method allows double checking of your transmission’s key systems, while providing you with added assurance.

Transmission Fluid Check

The fluid check indicates the first sign of possible wear and damage. A transmission in good condition will have a clear red fluid. If your fluid is discoloured or has unpleasant odour, this may be an indication of internal wear and damage which is occurring as you drive your vehicle. An unpleasant odour and discoloration, in combination with other symptoms, may require an internal inspection of your transmission.

Road Test

The road test consists of two segments: a stationary test and driving test, which together comprise the most detailed portion of the Multi-Check. Every position of your transmission will be thoroughly tested for slipping, noises, harsh, soft or erratic shifting, as well as late or early shift patterns.

Why Choose Us

Lift Inspection

During the lift inspection our technician will check the following:

  • Neutral Switch
  • Engine RPM
  • Throttle Linkage
  • Modulators
  • Transmission Mounts
  • U-Joints
  • Fluid Retention
  • Electronic Controls

This will determine if a minor adjustment will correct the problem of your transmission.

Pan Examination

In all pans, there are some metal particles and friction material present. However, an excessive amount indicates internal wear and damage. If that is the case, and it is determined that a minor adjustment will not correct the problem, we will recommend Mister Transmission’s inspection service. This service will determine exactly what is wrong inside your transmission.

Inspection Service

Your transmission is one of the most complex systems in your vehicle, with hundreds of precision parts operating together. Determining the problem and providing a price sometimes requires removing and even dismantling your transmission. Not only will we be able to determine the problem, we’ll also be able to determine the cause to prevent any future problems. Some of these services will require additional charges, which we will request you authorization prior to the work being performed.

Transmission Fluid Change Service

We also offer a transmission fluid change service to help ensure your transmission continues to operate at its best for years to come.

A few weeks ago, I had a great transmission fluid experience at this branch of Mister Transmission. I purchased a used Hyundai Tucson but unfortunately this car’s maintenance history is not complete. I decided not to take a risk of damaging its transmission and change its transmission fluid. This Mister Transmission location did a complete transmission fluid change and my car’s transmission perform much better after the change!!

Gus was very professional and took the time to patiently review a number of documents that were provided by the dealership so that I fully understood all the codes being displayed with respect to recalls from Dodge. He was very approachable and forthcoming in answering all my questions.

Sujosh Koshy
I had my transmission repaired at Mr transmission scarborough location on 13 th of sept 2024. The car ran fine after the transmission repair but recently on march 13th 2025 this month while i was driving the car completely lost the connection i couldnt move the car. The car was on drive with ignition on but it wont move only the engine would race. I dont know what went wrong i had to tow it to Mr transmission at 4900 sheppard ave. East because thats the intial place i got my transmission repaired and i had a 1 year and 20000 kms warranty on it. GUS was there to help me he checked out the vechile and found it was not all a transmission issue. It was a broken electrical wiring from main harness to pcm. My car was repaired and was back on road in few days. Thanks to Mr transmission. I would really recommend it to everyone with transmission issues
