Automatic Transmission Service | Fluid Change & Repair | JHG

At John Hughes, we provide expert automatic transmission servicing to keep your vehicle shifting smoothly and reliably.

Your transmission is a complex system that manages power delivery from the engine to the wheels. Over time, fluid degrades, components wear, and performance can decline. Our experienced technicians use advanced diagnostic tools and high-quality fluids to service your transmission, ensuring optimal performance and longevity.

Why automatic transmission servicing matters

Your transmission is under constant stress, especially in stop-start traffic or when towing. Without regular servicing, transmission fluid breaks down, parts can overheat, and shifting becomes rough or delayed. Left too long, minor issues can turn into major (and expensive) repairs.

Without regular servicing, you might start to notice delayed gear changes, strange noises, or even transmission warning lights. Servicing helps keep the fluid clean, protects internal parts, and extends the life of the system

Regular servicing helps:

Maintain smooth gear shifts and performance
Prevent overheating and excessive wear
Extend the life of your transmission
Identify leaks or faults before they worsen
Reduce the risk of sudden breakdowns

Not sure if your transmission needs servicing?

Here are some common signs to look out for (and why they matter).

01

Gears feel slow or clunky when sitting

If your car hesitates, lurches, or clunks when changing gears, it could mean your transmission fluid is low or worn out.

02

You’ve noticed a burning smell

Old or overheated transmission fluid can give off a burnt smell. This is often an early warning sign that something’s not right.

03

Transmission warning light is on

Modern vehicles will alert you if the transmission isn’t performing properly. Don’t ignore it. You should get things checked before bigger issues develop.

04

You’re hearing strange sounds

Whining, humming, or buzzing noises while driving could indicate a transmission problem, especially if the sounds change between gears.

05

It’s been a long time since your last service

Most manufacturers recommend servicing an automatic transmission every 50,000 to 100,000 km. If you’re overdue, it’s best to book in before problems arise.
