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.

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?

Eric and his techs were so good to me. I want to thank them. Eric just replaced my torque converter on my 2012 camry for the second time due to a faulty part. (torque converter) I went back to him after the initial converter install (about 5 months later) and I let him know the converter was acting up. He rediagnosed the vehicle and without hesitation said they would redo the job due to a bad torque converter under warranty. Job was done and Eric said that I did not owe him anything. Wow, what customer service. He definitely stands behind his work. The car is running great. I most definitely recommend Mister Transmission in St. Catharines. Thank you Eric!!!!
