Transmission Maintenance Services in North York
Over time, transmission fluid breaks down and gets contaminated, especially if you deal with extreme weather, city traffic or tow regularly. And when that happens, if left unchecked, it can cause extensive damage to the transmission.
Regular transmission service can also improve performance, reduce wear and tear and extend the life of your vehicle.
From a simple fluid replacement to a full service with filter and gasket change, at GTA Transmission we offer different levels of maintenance services to keep your vehicle running strong. We’ll guide you through what your vehicle actually needs.
Common Signs of Transmission Wear:
- Car won’t move even with the engine on
- Loss of power when accelerating
- Hard or delayed gear changes
- Trouble shifting into gear
- Slipping between gears
- Grinding or chattering sounds
- Leaks under the vehicle
If you’re noticing any of these symptoms, bring your vehicle in. We’ll check it out and let you know exactly what’s going on and what’s the best repair solution.
Do’s & Don’ts of Transmission Maintenance
✅ Do:
- A good rule of thumb is to perform a transmission fluid service (aka oil change) at every 30,000 km or once a year. But you don’t need to keep tabs. We will send you annual reminders when time is up
- Have your transmission fluid checked during oil changes. We can perform both, one stop maintenance and you are good to go!
- Always come to a full stop before shifting gears
❌ Don’t:
- Drive with low, contaminated or no transmission fluid
- Shift from drive to reverse while the vehicle’s still moving
- Spin your tires hard on turns (especially in FWD vehicles)
- Keep driving if you know there’s a transmission issue—it only makes it worse (please don’t do it!)
- Drag race your vehicle (it’s tough on the transmission, we’ve seen it)
- Use 4×4 mode on dry pavement unless your vehicle is designed for it
- Drive too long on mismatched or spare tires if you have AWD or FWD

Our Testimonials
The manager of GTA Transmission is an exceptionally skilled professional, particularly in all aspects of transmission repair. They resolved the issues with my vehicle's transmission within just two days and at a reasonable price. The manager took the time to answer all my questions thoroughly and in detail. This business is well-organized and efficiently run. I highly recommend GTA Transmission to anyone experiencing transmission problems with their vehicles.
Attended at GTA Transmission and had an inspection done on my transmission. There were other issues I wanted addressed as well. Derrick determined that there wasn’t a problem with my transmission and he promptly referred me to another garage across the way better suited to what I needed to be done. What honesty and integrity! I haven’t experienced that in a long time. I would highly recommend Derrick and his company. Makes me feel good about people again.
Excellent and speedy service! I have a 2015 Ford Focus and my clutch got destroyed. Ford told me they wouldn't be able to get me in for a month and a half. GTA Transmission Repair Corp. got me in that same day. They were able to diagnose and repair my issue within a week, even taking into account my need to have my car back before the weekend.
Best auto repair experience I have ever had. If you have transmission issues, GTA Transmission Repair Corp. should be your first call!
Derrick and Alessandra were both very kind and accommodating people. They came in on a Saturday to see my car, and Derrick was very thorough and helpful in explaining everything he was talking about (while seeming very knowledgeable). The diagnostic was very fairly priced, and they even offered to credit the amount spent on that to a repair there if I ended up needing one…
Five stars all the way! Derrick and Alessandra were super nice and professional from start to finish. A transmission rebuild is a major deal, so I was, of course, nervous in all respects. But they made me feel at ease, Derrick with his extensive knowledge and thorough explanation of all of the many details I needed to know about the process (before, during and after the job), and Alessandra with her warmth and professionalism in the office with the paperwork…
I went to GTA Transmission when my transmission fluid was very low and I was in a hurry. They topped it up for me quickly and got me back on the road in no time. Fast, helpful, and professional service. I really appreciated their support — highly recommend!
