If you’ve landed here, chances are you’re looking for a transmission shop run by real people, who care and deliver. We’re so glad you found us.
(And if you’re wondering about that cute floating yellow car, it’s also real. It belongs to a family member. We rebuilt its transmission, of course.)
Here’s the thing:
We’re not a dealership.
We’re not a franchise.
And we’re definitely not a cash-only, quick-fix shop using parts of questionable origin.
We’re still a mom-and-pop shop at heart – proud of it – but we’ve grown beyond that. Just not so big that we’ve forgotten our roots or our values. We’re still that passionate, independent shop, but investing in the same tools and training as the big names, hiring licensed technicians and offering perks that even some franchises don’t. And delivering it all with the care, consistency and integrity only a true local business can offer.
Simply said: we’re the alternative.
Trusted, local and independent.
As a woman-led, family-run transmission repair shop, we’ve built more than a business: we’ve created a customer-first space where clear communication, honest diagnostics and high-quality craftsmanship come standard. With digital vehicle inspections, financing options, courtesy Hertz rentals and Uber rides, we’ve thought through the details, so you don’t have to.
Our fully licensed 310D and 310S technicians bring decades of hands-on experience with automatic, manual, CVT, DCT and hybrid transmissions.
Whether you need a full rebuild, a clutch replacement, driveline service or preventive maintenance, we diagnose, explain and repair with precision and care—no pressure, no upselling, no mechanic jargon.
To top it all off, we’re the first—and only—CAA-Approved transmission shop in North York, with 100% customer satisfaction to back it up. Yep, we made our daughter proud. 🙂
Book your visit today and see why customers travel from across the GTA—even Muskoka and London—for transmission service they can truly trust.

Transmission & Driveline Repair Services in North York, ON
Transmission & Driveline Services
We offer complete transmission and driveline services, including rebuilds (aka overhauls) for automatic, manual, DCT, CVT, AWD, 4×4 and hybrid systems. Our team handles repairs for all makes and models—domestic or foreign, light to heavy-duty—including manual and dual clutches, torque converters, valve bodies, axles, differentials and transfer cases.
Replacement Options
Recycled replacement units don’t need to mean a risky alternative. We install only low-mileage transmissions and driveline components from selected trustworthy suppliers, offering a fast, budget-friendly solution, with warranty coverage on parts and labour (when available) for an added peace of mind.
Clutch Repair
Manual clutches or automatic DCT systems—different technology, same care. If your vehicle isn’t shifting the way it used to, don’t wait. Clutch issues can go from minor to major at any moment. We’ll check it thoroughly, explain what’s going on and tell you exactly what’s needed. No pressure. No guessing. Just the right solution, from people who know transmissions and clutches inside and out.
Preventive Maintenance
It’s not a myth: Transmission fluid service is one of the most important steps in preventive maintenance. It keeps your transmission running properly and helps extend the life of a rebuild. We use manufacturer-recommended fluids and service intervals to protect your investment, and we’ll even remind you when your next one is due.
Digital Vehicle Inspections (DVIs)
Why do I need another check? My mechanic already looked at it.” “I know what the problem is.” We hear this all the time. But here’s the truth: around 60% of the transmission concerns that come to us were misdiagnosed. Not because other shops mean harm – but because transmission inspections require specialized tools, training and experience to diagnose properly.
Fleet Services
Our fleet services are designed to minimize downtime and simplify maintenance with priority scheduling, digital tracking for each vehicle and early-bird appointments. We offer Uber rides within 15 km, consolidated monthly invoicing for fleets over five vehicles, volume-based discounts and extended repair services including brakes, suspension and general mechanical work.

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!

Our Reviews
Another 5-star review from a repeat customer :-).
After my vehicle reached 310,000 km, I began hearing clicking sounds from the transmission that concerned me. Remembering my previous positive experience with Derek, I asked him if he could spare five minutes to assess the issue. It took Derek only two minutes to identify the source of the noise, reassure me that no urgent repair was needed, and explain which symptoms would require further attention. I highly recommend this shop to anyone experiencing transmission problems.

Eventually codes did appear, gave Derick a call he advised that pressure switches would need to be replaced, and was able to provide a quote.
Took my car in for a rebuilt valve body and Pressure switches back in October 2025, and a month later I can say that my car performs exceptionally well.
Thank you Derick and your team for the honest advise, diagnosis and repair, I couldn’t have asked for a better experience!
For anyone looking for great transmission shop, trust me, Derrick is one of very few who actually knows how to get the job done properly! Great transmission expert and just an amazing person, thank you for giving my car a second chance!
Derek took the time to explain the possible probable causes with earnesty.
In fact the whole GTA team including the office staff Alexandra and Audry I felt I was in good hands and well taken care of.
I will defintely bring my car there for future services when needed.
I would hands down recommend GTA Transmission.
