Automatic Gearbox Servicing – Brentwood

Automatic gearboxes require regular maintenance to stay smooth, responsive, and reliable.

Over time, transmission fluid degrades, affecting performance and increasing wear. At Mercury Car Centre, automatic gearbox servicing is carried out in line with manufacturer guidelines, covering fluid replacement, filter changes where applicable, and full system checks.

Where a standard service isn’t enough, we also carry out a complete transmission flush, removing all old fluid from the system before refilling with fresh, correctly specified fluid. This gives a far more thorough result than a drain-and-fill alone and is particularly beneficial for vehicles with higher mileage or fluid that has been left too long between changes.

Where appropriate, this process is carried out using our specialist BG Mega Flush system, which ensures a complete and controlled exchange of automatic transmission fluid throughout the gearbox, torque converter, and oil cooler.

Ignoring servicing can lead to costly repairs later on so regular maintenance can help extend gearbox life and maintain smooth operation. Drivers often notice symptoms such as delayed gear changes, slipping, or hesitation; these are early signs that servicing may be overdue.

We use the correct specification fluids for each vehicle, ensuring compatibility and long-term protection. Where required, advanced diagnostics are used to assess gearbox performance and identify any underlying issues. If more complex faults are present, we provide a clear assessment and discuss the next steps before proceeding.

Our approach focuses on accuracy and transparency so you’ll know exactly what your vehicle needs and why it matters.

Automatic transmissions are sophisticated systems, but with proper care at Mercury Car Centre in Brentwood, they can remain reliable for many years.
