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 Gearbox Servicing & Repairs

We can help with a range of automatic transmission services, including:

  • Automatic transmission fluid checks and changes

Using the Correct Transmission Fluid

Automatic transmissions require specific fluids, depending on the type of gearbox and manufacturer.

Using the wrong fluid can cause serious damage. That’s why we:

  • Check manufacturer specifications

  • Use the correct-grade transmission fluid

  • Follow the correct service procedures

If your vehicle requires specialist fluid or a specific service method, we’ll let you know upfront.

Honest Advice. Clear Costs.

Automatic gearbox work can be complex, which is why transparency matters.

If we identify additional issues:

  • We’ll contact you before doing any further work

  • Nothing goes ahead without your approval

  • You stay in control of the cost

If a repair isn’t economical, we’ll be honest about that too. If this is something we are unable to fix we can recommend a specialist and guide you through.

Automatic Transmission FAQs

Yes. Most manufacturers recommend servicing the automatic transmission at specific mileage intervals, even if it’s described as “sealed for life”.

It usually means sealed for the expected lifespan of the gearbox under ideal conditions. In real-world driving, fluid still degrades over time.

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.

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.

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.

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.
