Services

Transmission-only specialists. Other shops, other dealers, other independents send their hardest jobs here.

  1. Transmission rebuilds & overhauls

    Full tear-downs and rebuilds with proper fluid temp and pressure verification. ZF 6HP, planetary gear, transmission plate, mounts — done in days, not weeks.

  2. Valve body service

    Porsche PDK, ZF and similar valve body repairs at a fraction of dealer estimates. Hard shifts, hesitation, slow engagement — diagnosed and fixed.

  3. Diagnostics & second opinions

    If a garage quoted you a swap, get the box looked at first. Customers regularly arrive after a $3,000+ quote elsewhere and leave with a repair instead.

  4. Transmission service & mounts

    Fluid service, transmission plate, transmission and engine mount replacement — the supporting work that keeps a rebuild lasting.

  5. Warranty-backed work

    Repairs come with warranty coverage. If a part fails inside the term, it gets replaced at no charge — turnaround typically the same day.

Reviews

Pulled from Google. Customers came in with hard shifts, dealer quotes, and second opinions in hand.

Line PDK · Porsche

These guys are the best !!!!!! I had called a repair shop in Oakville in regards about shifting issue on my Macan GTS . They immediately told me to contact Toronto automatic transmission and speak with Matthew . I called in and Matthew guaranteed the issue caused by it and said a fraction of the price to repair the PDK valve body . The date he promised the repair will in-fact be completed was on time !! . After picking up and driving the Porsche local and highway speeds it felt like night and day !!! Smooth shifts , no hesitation etc … so to Anyone with the Porsche PDK issues check them out!!!!! 🙏

Line ZF · 6HP28X

Great transmission and valve body service, and highly recommended. I had a ZF 6HP28X with well known wear and tear issues causing hard shifts. Matt and the crew rebuilt it all, and it moves smooth up and down like it should. I appreciate the expertise and labour that it takes to tear these down and replace many parts involved, then get the fluid back up to temp and at the right level so the pressures are properly managed when the vehicle needs to change speeds. Very cool stuff.

Line MB · C300

I brought my 2010 C300 to three different garages. The first garage diagnosed it as a planetary gear issue and said it would require a transmission swap, costing over $3,000 with a used transmission. I wasn't comfortable with that option. That referral led me to Matt at Toronto Automatic Transmission, and I couldn't be happier. Matt diagnosed the car, clearly explained all the needed repairs, and had everything done within two days at a very reasonable price. My car is now back on the road and drives like new.

Line OH · Overhaul

Really good experience with this guys considering that having to fix your transmission is very expensive and nothing pleasant there 😞 They did a transmission overhaul in exactly the time that they told me it will take and for considerably less money that other places where quoting me… I did had to come back after initial fix cause one of the parts they installed during an overhaul was faulty, again they did it in a day and costed me nothing because it was under warranty (1 year/20 000 km). I mostly dealt with Matthew… Big recommendation for this guys 👍
