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.

I have a 2018 Ford Ranger that had a transmission problem. My mechanic made several attempts to fix it and finally told me that he could send it our to a transmission specialitst and it would be approx $2,000. I took it to Gary and he fixed it the next day for much less. It is running beautifully!
