Automatic Gearbox Flushing

Automatic gearbox flushing is a maintenance procedure aimed at cleaning and renewing the transmission fluid within an automatic vehicle's gearbox. It helps ensure longevity and smooth operation of the transmission system.

Automatic gearbox flushing involves using specialized equipment to remove old, contaminated transmission fluid from the automatic gearbox and replace it with new. During a flush, the system is thoroughly cleaned to eliminate debris, sludge, and any contaminants that could negatively affect the gearbox's performance.

The process involves connecting a flushing machine to the vehicle’s transmission system. The machine forces fresh fluid through the system, displacing the old fluid. This allows for more thorough cleaning compared to a typical fluid change, which might only drain and replace fluid without fully cleaning the system.

Why is Automatic Gearbox Flushing Important?

Improved Performance: Over time, automatic transmission fluid can become dirty and degraded. This can lead to poor shifting, slipping gears, and overall decreased performance. Flushing the automatic gearbox helps restore optimal fuel efficiency and performance by ensuring the system operates with clean, effective fluid.

Extended Lifespan: Regular flushing of the automatic gearbox can help prolong its lifespan. By removing contaminants that cause wear and tear on the internal components, automatic gearbox flushing reduces the risk of costly repairs and the need for a full transmission rebuild or replacement.

When Should You Consider Flushing Your Automatic Gearbox?

Manufacturer Recommendations: Many vehicle manufacturers provide guidelines on when to flush the automatic transmission fluid. This can typically range from every 30,000 to 60,000 miles, but it is best to check the owner’s manual for specific recommendations or contact us for advice. Some “sealed for life” automatic gearboxes have no interval, but should be serviced. Contact us for advice.

Signs of Deterioration: If you notice a change in your automatic gearbox’s performance, if it feels sluggish or slow to change gear, it may be time for action.
