Automatic Transmission Service & Repair Markham, Ontario

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.

I went to see Ken Barone of Mister Transmission to replace the Solenoid in the Valve Body. It all started, when the dashboard in my 2016 Forester lit up like a holiday tree, the ATOil, incline assist, ABS, and other lights were flashing. There was a suggestion at another garage that I needed to replace the whole Valve Body, but Ken felt that replacing the Solenoid was all that was needed. Galo of Active Green & Ross at Steeles and Don Mills, had referred me to Mister Transmission who did a fantastic job of fixing my car.
