Here’s what happens when your vehicle comes in for a Comprehensive Diagnostic Service at GTA Transmission:
First, we gather your vehicle’s information and begin a Digital Vehicle Inspection (DVI). Everything we see and do is documented from the start—with photos, notes, and clear explanations—in a format you can easily view and keep.
Then, one of our licensed transmission technicians takes the vehicle for a test drive, if possible and safe. This lets them feel how it behaves in real-world conditions—paired with a professional-grade scan tool that reads your vehicle’s onboard systems. We collect specific codes that point us to how your transmission is performing and where issues may be coming from.
We also check the transmission fluid, looking at colour, smell and signs of contamination, and we search for recalls or manufacturer bulletins that may relate to your concern.
Once everything is done, we’ll walk you through our findings in plain language, explain what’s going on and outline any recommended repairs.
If you decide to do the repair with us, we’ll credit the cost of the inspection toward the repair. If you don’t move ahead, that’s okay too—you still leave with a complete digital report, photos and all, sent directly to your email, text or both.
All our communication, from approval to updates, will be sent the same way, so you always know exactly what’s going on with your vehicle.

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!
