Automatic Transmission Service & Repair Barrie, 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.

Had a leak from the pan and front seal on my transmission. Despite being busy these guys were able to seal up the pan within one day. No leaks from the pan. I decided to hold off on the main seal as it is a slow leak and I'll deal with it in the winter when the cars in storage. Thanks

Cathy Gellegan-Colby
Jason as the first voice you hear when you call Mr Transmission was friendly and helpful. The personal interaction with him was refreshing and he was so welcoming. He was efficient and knowledgeable and explained what they would do to help us figure out why my van was so loud. Within 6 hours, we got my van back sounding better and was given a list of what else my van needed to get done at our regular mechanics. Thank you to Jason and the crew at Mr Transmission Essa Road for the great service!

Richard Woehl
Outstanding service. Professional, honest and courteous. I believed I was in for a major expense for my F 150. Lorenzo diagnosed the issue while we were driving home to drop me off. It ended up being a cracked vacuum hose. The same afternoon he called me and said my truck was ready to go. When I asked about the cost of the repair, his response was don't worry about it. NO CHARGE!! Unbelievable in this day. Most of the " big boys" would be reaching for your wallet. Would highly recommend this business.

Doug Baumken
So I just purchased a 2015 Evoque . There was nothing wrong with the trans , I just wanted to do any required maintence . The manager told me that Range Rover does not recomend any fluid change . Now he could have told me that , YES he could change the filter and fluid and bill me $500.00 plus , but he did'nt , he told me the truth , which I might add does not happen to often anymore . I highly recommend this business , and it's not hard to understand the reason why they have been in business so long . Thank You -SIR, for your honesty
