Automatic Transmission Services at The Garage
Automatic gearboxes are designed to make driving smoother and easier – but they still need proper maintenance to stay reliable.
At The Garage, we carry out automatic transmission checks, servicing and repairs using the correct manufacturer grade fluids and procedures for your vehicle. Whether your gearbox feels rough, slow to change, or just isn’t behaving as it should, we’ll take a proper look and give you clear advice.
No guesswork. No unnecessary work.
Why Automatic Transmissions Need Maintenance
Unlike manual gearboxes, automatic transmissions rely heavily on specialist fluid to lubricate, cool, and control gear changes.
Over time, this fluid:
Breaks down
Becomes contaminated
Loses its ability to protect internal components
If left too long, this can lead to poor performance, overheating, and expensive repairs.
Signs Your Automatic Gearbox May Need Attention
You may notice one or more of the following:
Delayed or harsh gear changes
Slipping between gears
Juddering when pulling away
Warning lights on the dashboard
Unusual noises
Burning smells or fluid leaks
If something doesn’t feel right, it’s best to get it checked sooner rather than later.

Automatic Transmission FAQs
Do automatic gearboxes need servicing?
Yes. Most manufacturers recommend servicing the automatic transmission at specific mileage intervals, even if it’s described as “sealed for life”.
What does “sealed for life” mean?
It usually means sealed for the expected lifespan of the gearbox under ideal conditions. In real-world driving, fluid still degrades over time.
How often should automatic transmission fluid be changed?
This depends on the vehicle, but many require a fluid change between 40,000 and 80,000 miles. We can check what’s recommended for your car.
Can I drive if my automatic gearbox feels wrong?
You can, but continuing to drive with gearbox issues can cause further damage. If you notice slipping, harsh changes, or warning lights, it’s best to get it checked.
Is automatic gearbox work expensive?
Costs vary depending on the issue. Regular maintenance is far cheaper than repairing or replacing a damaged gearbox, which is why early checks are important.
Do you work on different types of automatic gearboxes?
Yes. This includes traditional automatics, dual-clutch gearboxes, and CVT systems. We’ll confirm what type your vehicle uses before any work is carried out.
