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

Can’t speak to quality, too early. But given the rest of my experience , no doubt, the quality will also be exemplary. Well done!
Great service and very honest. Derek spoke to me -a woman like a person. He explained without putting me down.
Derek was fantastic No hidden fees Did what he said the truck needed Keep up the terrific work Frank
Derrick is a genuine Machanic. got my car working again when no one wanted to touch a 2012 Ford Focus transmission. The cost for repairs was half the price I got from other shops Thank you.
I’ve never met such an honest mechanic! Derrick has a lot of knowledge in what he does. He takes his time and gets the job the done. I wish he was an all around mechanic shop! Very pleased with my car!
Car is running fine. Gears are shifting quite smoothly so I am a happy camper 🙂
Dereck & Alessandra were excellent to work with. Highly recommended.
I am lucky enough to have Derrick worked for me! He is definitely a great, talented and hardworking person! Thanks a lot!

Will definitely refer your company if & when I hear from friends that they need the service.
Hi, i brought my 2013 ford edge for a transmission repair at around 125k km. I'm at around 240 k km now and the only things that still work are the Power windows and transmission - that's it.
Hi Alessandra, my car works peeerfect! I'm loving it since. Thank you very much!
... it's an honest truth as I had many bad experiences with shops who didn't even touch my vehicle but charged me, I was trying to keep up with the transmission maintenance and every time I was just assured that work was done which in fact it wasn't and here I am without my work vehicle and crippled business, I wish I have found your shop years ago…
I was happy with the service provided and communication from the reception and techs.
