CVT Transmission Care: What Owners of Japanese Imports Should Know

Many popular cars in Jamaica, including models from Nissan, Toyota, Honda, Suzuki and Mitsubishi, use a CVT, or continuously variable transmission. CVTs are smooth and fuel efficient, but they need the right care.

How a CVT is different

Instead of fixed gears, a CVT uses a steel belt or chain running between two pulleys that change size. This gives an endless range of ratios, keeping the engine in its most efficient range.

Fluid is critical

CVTs need a specific type of fluid. Using the wrong fluid, such as standard automatic transmission fluid, can damage the transmission. CVT fluid also breaks down with heat and use, and heat is something Jamaica has plenty of.

Some manufacturers describe their fluid as "lifetime," but in hot climates with heavy traffic and hills, many mechanics recommend changing it periodically. Ask your mechanic what's right for your vehicle.

Warning signs of CVT trouble

• Whining or humming noise that changes with speed

• Shuddering or jerking, especially when pulling off

• Slipping or a delay before the car moves

• High revs without matching acceleration

• Transmission warning light or check engine light

• The car going into a low-power "limp" mode

Tips to make your CVT last

• Use the correct CVT fluid for your model

• Avoid harsh acceleration from standstill

• Don't overload the vehicle or tow beyond its limits

• Let the car warm up for a moment before driving off

• Get any shudder or noise checked early

Early diagnosis saves money

A CVT problem caught early may be fixed with a fluid service, a software update or a sensor repair. Left too long, it can mean a full transmission replacement.
