Automatic transmission: how to prevent failures and overheating
The automatic transmission is a sophisticated component that requires specific care. Increasingly, vehicles show issues such as gear shifting difficulties, slipping, or performance drops—symptoms that, if neglected, can lead to complete system failure.
Why does an automatic transmission get damaged?
The main causes of malfunction are often linked to poor maintenance or the use of unsuitable lubricants. These factors lead to:
- Abnormal friction: causing excessive temperature increase.
- Metallic residues and sludge: debris that clogs oil passages, compromising smooth gear shifting.
The professional solution: cleaning and protection
To restore proper functionality, it is not enough to replace the oil; a complete treatment is required that works in two phases:
- Deep cleaning: we use specific automatic transmission cleaners that remove impurities without damaging seals and delicate elastomer components.
- Enhanced lubrication: once the system is cleaned, a new specific lubricant is introduced, enriched with additives that increase the protection of mechanical components and help stabilize operating temperature.
When should maintenance be performed?
To ensure maximum longevity of your automatic transmission and prevent sudden failures, we recommend a cleaning treatment and lubricant replacement:
- Every 60,000–80,000 km (or every 4–5 years) for standard vehicle use.
- Every 40,000 km in case of intensive use, towing loads, or predominantly city driving.
The Sintoflon protocol: guaranteed reliability
Based on our experience and positive customer feedback, we recommend a combined treatment using Sintoflon products, a leading brand in the industry:
- SINTOFLON FLUSHMATIC: added before the oil change, it performs a complete and safe system flush, removing all traces of contamination.
- SINTOFLON LUBEMATIC: added to the new lubricant, it enhances protection performance, helps prevent premature oil degradation, and keeps operating temperatures under control.
Avoid costly repairs: choose high-quality preventive maintenance.
