Trusted Transmission & Driveline Services in North York
At GTA Transmission Repair, we focus on one thing and do it well: repairing transmissions and driveline systems the right way. Whether you drive a domestic truck, an imported vehicle or a hybrid SUV, our licensed 310D and 310S technicians bring the experience, tools and attention to detail your vehicle deserves. From full rebuilds to targeted repairs, we diagnose the issue, explain your options and get you back on the road with confidence.
Transmission Rebuilds
We offer complete rebuild (aka overhaul) for all transmission types: automatic, manual, DCT (dual-clutch), CVT (continuously variable) and hybrid systems. Each overhaul is tailored to the specific needs of your vehicle, using high-quality components and backed by warranty coverage. Our team will assemble, inspect and reassemble your transmission to meet or exceed OEM standards.
Transmission Repairs for All Makes & Models
From light-duty sedans to heavy-duty work trucks, our shop is equipped to handle complex transmission repairs for domestic and foreign vehicles alike. We also offer performance upgrade options for customers looking to boost power or towing capacity. No matter the issue, we provide accurate diagnostics and reliable repairs to restore smooth shifting and drivability.
Manual and Dual Clutch Transmission Repairs
Our technicians are trained to repair and service standard manual gearboxes and advanced DCT systems. Whether you’re dealing with grinding gears, clutch slippage, or synchronization issues, we’ll get you back on the road with confident, responsive shifting.
Torque Converter Services
We perform advanced diagnostics and repairs on torque converters, including full replacement if necessary. Common symptoms like shuddering, stalling or slipping can point to torque converter failure, something our specialists are trained and equipped to fix efficiently.
Valve Body Diagnostics and Repairs
The valve body is a crucial component in automatic transmissions, directing fluid to where it’s needed for shifting. If your vehicle is experiencing erratic or delayed gear changes, our team can diagnose and repair valve body issues with precision to restore proper transmission function.
Axle, Differential and Transfer Case Repairs
We provide full-service driveline repairs, including axle replacements, differential repairs and service to transfer cases in AWD and 4×4 systems. Whether it’s a leaking differential, worn CV joint or transfer case issue, we ensure your vehicle’s powertrain stays safe, balanced and road-ready.

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.
