Transmission Maintenance & Service in Sarnia, Ontario

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.

Hi I had my 1966 Chevelle Malibu SS in at Mister Transmission Sarnia to have the transmission worked on last year. Mike in the back shop worked on my car (pride and joy). He did the repairs that was needed done and a few extra things done without request. The car ran like a dream when I got it back. The cost was lower then they said it would be. I'm very fussy on who works on my car. The owner (manager) was awesome to deal with. Then this week 04 July 2025 I needed a shift cable repaired as I was headed out with my car . I went to the shop and they were over loaded with work. Mike made time to get my car fixed so I could use it on the weekend. They went the extra mile to get my car fixed and again I could not complain about the cost to repair the cable. I fully recommend them and the people that work there are outstanding. A special thanks to Mike who worked on my baby(my car) thanks so much guys. They are my go to shop with my Classic car and all my vehicles.
