Automatic Transmission Service & Repair Port Union, ON

The transmission is the most complicated component of your vehicle, and with the technology being used in today’s vehicles evolving every year, transmission repair requires more skill and knowledge than ever before. The automatic transmission used in today’s vehicles includes a combination of hydraulics and computer-controlled components. At Mister Transmission, we have state of the art diagnostic technology to determine exactly what is going on with your vehicle, and the most cost-effective solution to repair it.

Automatic Transmission Common Problems 

There are many warning signs that could indicate you have a problem with your transmission, including:

  • Transmission slipping or rough shifts
  • Fluid leaks
  • Burning smell
  • Contaminated or low transmission fluid
  • Overheating
  • Check Engine Light On

My vehicle is showing at least one of these signs, what should I do?

If you suspect your automatic transmission is not performing as it should be, bring it into your local Mister Transmission. We always start with our FREE Road Test and Multi Check Inspection to identify any problems with your transmission and provide you with different repair options. The key to minimizing repair costs is to get them checked as soon as you notice them, and you most likely only need a minor repair or service.

Nathan Boudreau
I went here and spoke with Ray and he gave me a price on the labour for installing a TCM in my ford focus. He then recommended me to standard auto wreckers to choose the part that fit best for my needs. Once I went back for them to begin the installation they stuck to the price that Ray gave me initially and my car was ready just a few hours later. All around the staff were helpful and nice. Getting something fixed on my car usually is terrible, the staff her made the experience much better with the extra effort they put in. I would return here if I need a transmission repair in the future.

They know what they are doing… and they are very straight forward. In my case it was a $2600 fix but the Job was done. For transmission issues save yourself stress and use thier service.

Aaron Asuncion
Called Gus to get a quote on a transmission service for my Volkswagen. He was friendly, gave me a fair price, and understood that I needed the service done ASAP — he accommodated me quickly and professionally.After the service, I drove around but felt a bit paranoid about some vibrations. I brought the car back the same day, and without hesitation, his team double-checked everything, including another road test, to make sure my car was running properly.As someone who runs his own business, I really appreciate Gus’s professionalism and approachability. A lot of other mechanics I’ve been to give off this energy that you know nothing and should just pay them but I definitely didn’t get that vibe from these guys.Definitely recommend this shop — and I’ll be coming back for future service.

Two years ago. brought my SUV to Ray and Gus at Mr. TRANSMISSION. It was the best decision I ever made on going to the right guys to get the job done and especially a quick turnaround time. I brought my second vehicle to them with a blown TCM and they had the car ready in less than two days. Thank you guys over there at Mr. TRANSMISSION.
