What’s the Difference Between Automatic, Manual, and CVT Transmissions?

January 30, 2026 | By Mister Transmission

Automatic Transmission

An automatic transmission shifts gears automatically without driver input. It uses a combination of transmission fluid, sensors, and internal components to determine the best gear based on speed and driving conditions. Automatic transmissions are popular for their convenience and ease of use, especially in city driving and heavy traffic. They require regular maintenance, including fluid service, to ensure smooth shifting and long-term reliability.

Manual Transmission

A manual transmission requires the driver to change gears using a clutch pedal and gear shifter. This type of transmission gives drivers more direct control over gear selection and engine power. Manual transmissions are often valued for their simplicity, durability, and lower maintenance costs, though they require more driver involvement and skill. A worn clutch is the most common issue associated with manual transmissions.

CVT Transmission

A CVT transmission (Continuously Variable Transmission) operates differently from traditional gear-based systems. Instead of fixed gears, it uses a belt and pulley system to provide seamless acceleration across an infinite range of gear ratios. CVT transmissions offer smooth performance and improved fuel efficiency but require specialized service and proper fluid maintenance to function correctly.

Each transmission type offers unique advantages depending on driving style, vehicle design, and performance needs. At Mister Transmission St. Thomas, experienced technicians service and repair automatic, manual, and CVT transmissions using manufacturer-recommended procedures.

This shop is great, they worked on my daughter's 2013 focus in 2017. When Ford would not honour their warranty. It is still going strong. I was told the transmission will out live the car. Well yes. It's time for a new veh with. Worked on my 2003 F150, great work, now my 2010, once again great work. They took time to find a miss, in the truck. I'm a car guy, and know shops that do great work. Yes everyone is never happy with the work. But for me there is always two sides.

Aidan Hennebry
Had to get my transmission redone on my 2017 Dodge Grand Caravan at 140k clicks. Sucked. My local shop quoted me a little over $8,000 for the repair. I decided to call around. Mister Transmission gave me tons of information, answered my billion questions (even before I'd committed to becoming a customer), were prompt in getting my van dealt with, and even gave me better parts than my local shop had quoted me for... all for $6,500. How they did all of that for cheaper than my first quote I do not understand (other than the fact that: They are the only transmission shop in town, and all other shops would just bring transmission rebuilds over here). 10/10 would return to in the future (but hope not to have to). Can't recommend them enough. Mark and the gang: Thank you guys for the incredible service.
