How Does a CVT Gearbox Work?
Instead of fixed gears, a CVT uses two cone-shaped pulleys joined by a steel belt or chain. As the pulleys change width, the ratio changes smoothly and continuously, keeping the engine at its most efficient speed. Most CVTs fall into one of three groups.
-
Push-Belt CVTs
The most common type in London traffic, including Nissan Xtronic (Qashqai, Juke, X-Trail, Note, Micra), Honda Jazz and HR-V, and non-hybrid Toyota automatics.
-
Chain CVTs
Use a chain rather than a belt to handle more torque. Found in Audi Multitronic on front-wheel-drive A4, A5, A6 and A7 models, and Subaru Lineartronic.
-
Hybrid e-CVTs
Toyota and Lexus hybrids use planetary gears instead of belts and pulleys. See our hybrid transmission repairs page.
Signs of CVT Gearbox Problems
CVT faults usually give plenty of warning. Catching them early can mean a targeted repair rather than a full rebuild.
- Whining, humming or droning that changes with road speed
- Shuddering when pulling away, creeping or accelerating gently
- Revs rising without the car speeding up
- A delay before Drive or Reverse engages
- Limp mode or reduced power, often after a long or hot drive
- Transmission or overheating warning lights
- A burning smell from overheated fluid
- Fluid leaking from seals or pipes
Why Do CVT Gearboxes Fail?
-
Fluid Problems
Old, low, overfilled or incorrect fluid is one of the biggest causes of CVT damage.
-
Belt or Chain Wear
A worn or stretched belt or chain causes slipping and flaring revs.
-
Pulley & Bearing Wear
The most common source of whining and droning noises.
-
Valve Body, Step Motor & Solenoid Faults
Cause slipping, delayed engagement and erratic ratio changes.
-
Control Unit & Sensor Failures
Trigger warning lights and limp mode, and are a known issue on Audi Multitronic.
-
Torque Converter & Clutch Pack Wear
The usual cause of judder when pulling away from a standstill.

CVT Gearbox Repair FAQs
A CVT (continuously variable transmission) is an automatic gearbox with no fixed gears. It uses two pulleys linked by a steel belt or chain, which change size to give a smooth, continuous range of ratios.
A CVT varies its ratio continuously using pulleys and a belt or chain. A DSG or other dual-clutch gearbox uses two clutches to switch between fixed gears. A torque converter automatic uses a fluid coupling and planetary gear sets. Each has its own typical faults, so a proper diagnosis matters.
A whine, hum or drone that changes with road speed is usually caused by worn pulleys or bearings inside the gearbox. Getting it diagnosed early is usually much cheaper than waiting until a full rebuild is needed.
If the revs rise but the car doesn't pick up speed, the drive is slipping. This is typically caused by degraded fluid, a worn belt or chain, or a valve body or step motor fault.
Judder from a standstill is usually caused by torque converter or clutch pack wear, although belt, chain and fluid problems can cause it too. Stop-start London traffic tends to make it more noticeable.
Yes. Many CVT faults can be fixed with a targeted repair, such as a valve body, step motor or control unit fix. Where wear is more extensive we can fully rebuild the gearbox, and we only recommend a reconditioned replacement when a rebuild isn't sensible.
With the correct fluid and sensible driving, many CVTs last well beyond 100,000 miles. Lifespan depends on the design, how the car is driven and how well the fluid has been looked after.
It depends on the fault and the repair needed. A targeted repair costs far less than a rebuild or replacement. We carry out a full diagnostic first and confirm the price before any work starts.
No. We use OEM or manufacturer warranty-approved parts, so your warranty is protected, and we can deal with your warranty provider on your behalf. Every repair is covered by our 12-month or 12,000-mile warranty on parts and labour.
