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
After a poor and deceitful experience from a previous shop, I went searching. A few shops came across my "Google search", so for months I read reviews and so on, then decided to go with GTA Transmission. I paid them a visit, had a little chat with Derrick before hand. I then, took my 2017 camry in for a drain and fill, that was due. That was done in reasonable time, at a fair price and I could feel the difference driving the car. I am pleased and will return.

I had a great experience with GTA Transmission Repair Corp. The service was excellent, and they were able to find the actual problem with my car quickly and accurately. Two other repair shops had pointed me in the wrong direction, but the team at GTA Transmission found the real issue and explained everything clearly. Very professional, honest, and knowledgeable service. I really appreciate their help and would definitely recommend them!

Derrick is a genuine mechanic. 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.
