CVT (Continuously Variable Transmission) Service & Repair Sarnia, Ontario

 

A traditional automatic transmission uses a complex series of gears to transfer the engine’s power to the wheels. A CVT is a type of automatic transmission, but it has no gears at all. Instead, it uses a pulley and belt system to provide an unlimited range of gear ratios. Popular auto makers, such as Nissan, Toyota, Subaru, Chrysler and Honda, are introducing CVT’s to their model lineups to offer customers an option with improved acceleration and enhanced fuel economy.

CVT Common Problems

CVT’s are still relatively new to the market and can be very difficult and complicated to diagnose and repair. While CVT’s have fewer moving parts and are simpler in design, it is new technology and our technicians have completed extensive training specific to CVT’s and are well qualified to work with your vehicle.

Come common problems to look out for with your CVT include:

  • Transmission ‘jerking’, slipping, grinding or jumping during acceleration when the car is shifting gears
  • Noisy while driving – some customers have issues with a ‘whining’, ‘clanging’ or ‘rattling’ sound while driving especially with Nissan CVT’s
  • Contaminated or low transmission fluid
  • Overheating
  • Check Engine Light On
  • Gears changing at high RPM

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

If you suspect your CVT transmission is not performing as it should be, bring it in to 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.

Best experience I've had in a shop in a long time, they were incredibly nice, explained to me the problem (worn cable, something was seized), and had my car in and out in a half hour.

Aybaniz Abdullayeva
I would highly recommend this shop to anyone from now on. My car had a problem that no other two places that it was towed could diagnose it, even they kept my car for some days. Then I called to Mister Transmission and talked to Bob, and he agreed to look at it. The friendly and skilled personnel of this place found and fixed the problem with no time for the reasonable labor charges.
