Compare Renault automatic transmission fluid replacement quotes from specialist garages

Transmission fluid lubricates moving parts and provides hydraulic pressure for gear changes. It deteriorates over time, so you should check the fluid level regularly and follow a regular transmission service schedule.

During an automatic transmission service, the fluid is drained and refilled, and the filter is replaced. Transmission fluid changes are essential to car maintenance and should be done every 30,000 to 60,000 miles. The key benefits are that fresh fluid will give you smoother gear shifts and extend the life of your transmission.

If you don't change the fluid in your car, it will degrade like engine oil, causing excessive friction, sludge build-up and high temperatures, which contribute to faults within the system.

Many drivers book an automatic transmission fluid and oil change together to save time. Manual transmissions typically run cooler than automatics, so they often require different types of liquid. You can find this information in your owner's manual.
