CVT Transmission Service
Also called CVT oil change
A CVT uses a steel belt or chain running between variable pulleys instead of fixed gears. It depends entirely on the correct fluid maintaining friction and cooling. Fluid degrades with heat and stop-start traffic, and using the wrong specification causes slipping and rapid wear. This service replaces the fluid and filter or strainer and checks for stored faults. It cannot reverse belt or pulley damage that has already happened, and we will tell you if the fluid shows that.
What the job includes
- Fluid condition inspected and any metal content noted before draining
- Drain and refill with the exact CVT fluid specified for your model
- Filter or strainer replaced and the pan magnet cleaned
- Fluid level set at the specified temperature, not by guesswork
- Fault codes and CVT adaptation data read before and after
- Road test checking for shudder, slip and correct ratio change
Signs you need this
- A shudder or vibration when pulling away gently
- The engine rises in revs without matching acceleration
- Whining that changes pitch with road speed
- Transmission warning light or reduced power mode
- The fluid interval for your model has been reached
Not all of these have to be present, and one of them on its own can mean something else entirely. That is what the diagnosis is for.
How we do it
Confirm the exact fluid
CVT fluids are not interchangeable, so we verify the specification for your model before anything is drained.
Inspect the old fluid
Colour, smell and any metal glitter on the pan magnet show whether the belt and pulleys are already damaged.
Drain, replace, refill
Fluid is drained, the filter or strainer is replaced, the pan is cleaned, and fresh fluid is filled.
Set level at temperature
Level is checked at the temperature the maker specifies, since CVT fluid level is very sensitive to this.
Reset and road test
Adaptation data is reset where required and a road test confirms smooth take-up without shudder or slip.
How we work
The same on every job, which is why we can write it down.
Diagnosis before quote
We find the fault first. A price given over the phone for a noise nobody has heard is a guess.
The price is agreed first
You approve the work and the cost before a spanner is picked up. Extra work means another call.
Parts you can check
We tell you whether a part is genuine, OEM, aftermarket or used, and what each one costs.
Old parts returned
Ask and we will hand back whatever we replaced. It is the simplest proof that the job was done.
