Local CVT Gearbox Repairs & Replacements for Automatic Transmissions

A CVT transmission - or Continuously Variable Transmission - is a form of single-speed automatic gearbox that has changed automatic transmissions as we know them. Designed with a single belt that can change shape according to the gear the car needs, CVT gearboxes effectively offer endless and seamless 'shifting' that isn't limited to a set of numbered gears. Even standard automatic transmissions have a set they have to stick to, but CVT completely shakes that up. There are several types of CVT systems, including pulley-based CVT, toroidal (disc-based) CVT, and hydrostatic CVT. Each system has its own design and engineering characteristics, but they all aim to achieve the same goal of providing continuously variable gear ratios.

The most common type of CVT uses a pair of variable-diameter pulleys and a belt or chain to continuously vary the transmission ratio, enabling the engine to operate more efficiently across a wide range of speeds. As the vehicle accelerates or decelerates, the pulleys change in size, altering the gear ratio to maintain optimal engine performance. However, despite the simple single-belt function, CVT gearboxes aren't immune to problems. Proper maintenance with the right fluids and care will reduce the chance of problems, however, issues can and do arise from fluid leaks to worn belts. For this reason, we are proud to offer CVT transmission repairs here at Service4Service.

CVT repair involves addressing malfunctions in the transmission system. This intricate process encompasses diagnosing issues through specialised tools, disassembling the CVT to assess internal components, identifying faulty parts such as belts, pulleys, or sensors, and then either repairing or replacing them. It also necessitates careful reassembly, followed by fluid flushing and replenishment. Our experienced technicians play a vital role in ensuring a comprehensive repair, aiming to restore the CVT's functionality, efficiency, and overall performance. Timely and accurate repair can extend the CVT's lifespan, providing a cost-effective solution compared to a complete replacement. Our mechanics are experts in a wide range of gearbox styles and CVT is no exception. Our team can run full diagnostics for your CVT gearbox and provide you with quick and efficient repairs where possible. With transparency from our technicians from start to finish and recalibration and configuration following the repair, you can rest assured that you'll get back on the road safely in no time.

Can a CVT gearbox be repaired after a fluid leak?

Yes, a CVT gearbox can often be repaired after a fluid leak. The repair process may involve identifying the source of the leak, sealing or replacing the damaged components causing the leak, and refilling the CVT fluid to the appropriate level.

How long will my CVT gearbox repairs take?

The time it will take to repair your CVT transmission will differ from case to case and can even change throughout the repair process as we work on your vehicle. We will give you an estimated timescale before starting work, and will remain in touch with you throughout so you aren't left out of the loop. Repair times can vary according to parts needed, work required and the demand at the time your vehicle is booked in.

What are the signs something is wrong with my CVT gearbox?

Some common signs of a CVT problem you can look out for include transmission jerking, slipping, grinding, whining, rattling, leaks, overheating and, of course, the check engine light coming on. You should also keep an eye on your RPM and whether the gears seem to be changing at an RPM that is too high. If you are experiencing any of the above, simply get in touch with a member of our team to book your vehicle in for diagnostics and repair.

Will my warranty still be intact after CVT gearbox repairs?

How much will my CVT repairs cost?

The cost of your CVT repairs will be calculated according to the cause of the problem, the make and model of the vehicle, the damage that needs repairing, any parts or labour needed to complete the repair and whether you require a repair or a complete CVT replacement. We will always provide you with a quote before starting any work, so you can approve the costs first.

Can a CVT gearbox be repaired if it's malfunctioning?

Yes, a CVT gearbox can be repaired if it's malfunctioning. The extent and complexity of the repair will depend on the specific issue. Some common repairs include replacing or repairing the CVT belt or chain, fixing pulleys, solenoids, and sensors, or addressing fluid leaks.

Are there any common causes of CVT gearbox failure?

Some common causes of CVT gearbox failure include overheating due to insufficient or contaminated fluid, a damaged or worn CVT belt or chain, internal mechanical or electrical issues, and lack of regular maintenance.

What are common signs of a failing CVT gearbox?

Common signs of a failing CVT gearbox include slipping or jerking during acceleration, unusual noises (whining, humming, or buzzing), overheating, delayed engagement, loss of power, and a burning smell. If you experience any of these symptoms, it's advisable to have your CVT gearbox inspected by a professional.

Is it possible to rebuild a CVT gearbox?

Yes, it is possible to rebuild a CVT gearbox. Rebuilding involves disassembling the CVT, inspecting and repairing or replacing damaged components, and reassembling it to function properly. This process should be carried out by experienced and trained technicians at Service4Service with expertise in CVT rebuilding.
