Maintaining Fuel Efficiency as You Drive

By Mister Transmission

More gears, electronic shifting, and dual clutches: here’s how modern transmissions are improving fuel economy

In the unending quest to increase vehicle fuel efficiency, some auto manufacturers are adding more gears to automatic transmissions. It’s two-pronged answer to improving vehicle mileage and adhering to increasingly stringent carbon dioxide emission standards for cars and light-duty trucks.

Adding gears to improve performance is not an entirely new idea, but much of the thrust for doing so concerning maintaining fuel efficiency is the idea that more gears reduce the engine’s operating range. That concept gave way to the creation of continuously variable transmissions (CVT). By keeping engine revs low, a CVT ensures no more fuel is burned than what is required for any type of driving.

Some people believe a manual transmission provides better fuel efficiency than an automatic transmission. There may be a hint of truth to that – and only just – but it depends entirely on the model of vehicle you drive. However, on the whole, a modern vehicle with an automatic transmission is more economical than one with a manual transmission.

Other Transmission Technology Advances

Expanding the number of gears in automatic transmissions or installing a CVT in a car are two approaches intended to increase and maintain fuel efficiency, but here are other options, including automated manual transmissions (AMT) and dual-clutch transmissions (DCT).

AMTs, aka automated clutch-manual transmissions, are thought to provide better fuel economy than other automatic transmissions because they have a clutch instead of a torque converter. That may not be indisputable with the invention of lock-up torque converters and electronic gear shifting. Nevertheless, AMTs also use electronics to shift gears and they provide a similar driving experience to a traditional automatic transmission.

DCTs, also referred to as a twin-clutch transmission, house two clutches: one for even-numbered gears, the other for odd-numbered gears. Compared to a traditional automatic transmission, DCTs reportedly reduce fuel consumption between 3% and as much as 9%. DCTs, powered by a car’s onboard computer, are becoming increasingly common in both domestic and imported vehicles.

The Drive Toward Better Mileage

It’s the automatic transmission innovations among competing auto manufacturers that are transforming the cars we drive, and their improving fuel efficiency. Since the mid-1990s, Canadian motorists have been gravitating toward purchasing vehicles equipped with automatic transmissions. That, in turn, led to the increasing rivalry between carmakers to develop more efficient transmissions.

Not to be overlooked, improving your car’s fuel efficiency requires more than adding gears or choosing a vehicle with a CVT. Sleeker auto bodies, buying high-quality tires, and regularly scheduled maintenance of your transmission can all add up to fuel cost-savings.

Wes was both knowledgeable and considerate, qualities which are rare today. I felt confident that he would repair my transmission in a competent and honest manner. I cannot say enough about how pleased I am with his service.

Cory Baron
Our regular mechanic referred us to Mr. Transmission after the CVT in our 2014 Nissan Pathfinder needed replacement. It is a far better option than working directly with the dealership. The price was fair, service was professional, expectations were clear, and there is a 3 year warranty on the work, compared to 1 year from Nissan. We had a minor post-service follow-up that they looked at with no issue or extra charges. We also had a second vehicle in for a suspension replacement and transmission flush. Phil kindly agreed to take my car on an additional road test to assure me all was good. I'm glad to recommend Mr. Transmission and appreciate the professional service from Phil and team!

Noel Smith
Very pleased with the assessment and repair of my vehicle. The technician also found and repaired faulty work from recent work performed by another business. Had this been missed it could have been very costly in the near future. Will use “Mr. T” in Calgary for all my service needs in the future.

Dream Space
I was referred to Mr. Transmission on Queenston Road in Stoney Creek when there were obvious issues going on with my vehicle. The owner is very nice and Dan went above and beyond. I truly appreciate all they did for me and would highly recommend them to anyone needing work done. My vehicle runs like a dream and I expect the work that was done will extend the life of my vehicle for another 5 to 6 years versus buying a new car. Thanks Dan/Mr. Transmission!
