  • The parts will then be cleaned before a new filter is installed and the sump refitted with a new gasket or sealing compound.
  • The gearbox will then be refilled with the correct ATF for the gearbox and application in accordance with the manufacturer's procedure.
  • In some cases the refilling operation requires diagnostic input as well as manual.
  • One refilled to the correct level and run through its selection routine, the vehicle will be test driven before returning it to the owner.

How often should an automatic transmission be serviced?

You should service the automatic gearbox as stipulated in the manufacturer's service schedule. Every vehicle with an automatic gearbox will have a service schedule, the same as the engine does. So this should be a regular occurrence in accordance with this, however in reality, few owners have it carried out until there is an issue, which in some cases it is too late and damage has been done.

Can I still drive with bad transmission fluid?

Driving with bad automatic transmission fluid (ATF) can result in many issues, such as transmission overheat, solenoid failure, jerky gear changes and even total gearbox failure. ATF provides the lubrication to the moving parts, wear and corrosion protection and is there to transfer the mechanical power. This is why regular servicing of an automatic transmission is vital to change this fluid (and its filter where fitted) in line with manufacturers recommendation.

If you suspect there is any issue with the transmission fluid or there are concerns about its age or condition, book a service with a professional mechanic as soon as possible.

 How do I know that the automatic transmission fluid has been changed recently?

First place to check will be the service records coming with the car. If you have a maintenance record of the car, it should be normally be noted in the service section. If there is no sign of a recent change, it's worth checking the condition of the fluid by checking the colour of the fluid - if the transmission fluid is clean and red or pinkish in colour, it was probably changed recently.

Is bad transmission fluid an MOT failure?

Bad transmission fluid in itself is not checked during an MOT so it is not likely to fail. However, it is best to do a full service before an MOT test, where most car fluids will be checked and replaced if needed.

How often should you change transmission fluid?

Most manufacturers suggest changing the transmission fluid every 30,000 miles or 2 years, whichever comes first. Each car is different so it's best to check the owner's manual for the specific recommendations.

What are the symptoms of too much transmission fluid?

Some symptoms of too much transmission fluid are:

  • Delay in shifting gears
  • A sticking throttle
  • A burning smell

Does automatic transmission fluid need to be changed?

Yes, on many vehicle transmission fluid (ATF) needs to be changed every 30,000 - 40,000 miles. There are however cars with 'sealed' transmission units which technically would never require an ATF change. It's important to check the owner's manual to see the recommendations for your particular vehicle. In some cases, the automatic transmission fluid will need to be changed sooner if you noticed that the fluid is dark-coloured and potentially has a burning smell.

Can too much transmission fluid cause the transmission to slip?

Yes, If the transmission fluid level is too high, it can cause the transmission to slip out of gear or not engage properly because there isn't enough space for the fluid to circulate.

What does transmission service mean?

A transmission service is the process of maintaining, primarily the automatic transmission system of a vehicle. A transmission service can help to improve the performance of the automatic transmission and extend its lifespan.

Are transmission flushes really necessary?

They're not always necessary, but in some cases a routine flush can help prevent the clogging up of the internal transmission lines.
