CVT Transmissions

A CVT (Continuously Variable Transmission) is a type of automatic transmission that delivers seamless acceleration without traditional gear changes.
Instead of using fixed gears like a conventional automatic, a CVT uses a belt-and-pulley system (or in some cases, a chain) to provide an infinite range of gear ratios. This allows the engine to stay in its ideal power range, improving fuel efficiency and smoothness.

Modern CVTs are commonly found in vehicles from Subaru, Nissan, Toyota, Honda, and Mitsubishi. While they offer excellent efficiency and comfort, they rely heavily on precise hydraulic control and clean transmission fluid to operate correctly.
Over time, wear in the belt, pulleys, bearings, or valve body can lead to issues such as shuddering, slipping, or delayed engagement.

At Central Automatic Transmission Services, we specialise in diagnosing and rebuilding CVT units using new OEM components and the latest updates to restore performance and reliability.

Common CVT Transmission Problems and Symptoms

Although CVTs are designed for smooth and efficient driving, internal wear or lack of maintenance can cause noticeable issues over time.
If you experience any of the following symptoms, your CVT may need servicing or repair:

·         Shuddering or vibration when accelerating from a stop

·         Jerking or slipping while driving

·         Delayed engagement when shifting from Park to Drive or Reverse

·         Whining, humming, or droning noises from the transmission area

·         Loss of power or poor acceleration

·         Warning lights or “Transmission Overheating” messages on the dash

These issues are often related to belt or pulley wear, pressure control faults, valve body problems, or contaminated transmission fluid.
At Central Automatic Transmission Services, our technicians use specialised diagnostic equipment to pinpoint the cause and can carry out complete CVT rebuilds using brand-new OEM components — restoring smooth performance and long-term reliability
