Standard automatic transmission maintenance
1. Fluid replacement
*Regular transmission fluid (ATF) changes are critical to transmission performance and longevity.
* Most manufacturers recommend replacing ATF every 60,000 – 90,000 km or every 3-5 years.
* Use only ATF fluid specified by the vehicle manufacturer.
2. Filter replacement
* The transmission filter traps contaminants and debris, protecting transmission components.
* When replacing the ATF, the transmission filter should also be replaced.
3. Eliminate leaks
* Repair any ATF leaks immediately as they can cause serious damage to the transmission.
* Inspect seals, gaskets and hoses for leaks and replace if necessary.
4. Adaptation and reprogramming
*After replacing the ATF or filter, the transmission may need to be adapted or reprogrammed to ensure optimal shifting.
*These procedures can be performed at an authorized service center or using a diagnostic scanner.
Advanced automatic transmission service
In addition to standard maintenance, the following may be required:
5. Flushing the gearbox
* Flushing the transmission removes accumulated dirt and deposits.
*This is a more thorough procedure that can extend the life of the transmission.
6. Replacing solenoids
* Solenoids control the flow of ATF in the transmission to ensure proper gear shifting.
* Faulty solenoids can cause shifting problems.
7. Repair of hydraulic unit
* The hydraulic unit is a complex mechanical part that controls the ATF pressure in the transmission.
* Problems with the hydraulic unit can cause serious transmission problems.
8. Major repairs
*In severe cases, the transmission may need to be overhauled, which includes replacing damaged or worn components.
* This is a costly and time-consuming process and should only be considered as a last resort.
Important:
*Follow the service intervals recommended by the vehicle manufacturer.
*Use only high quality ATF fluids and parts.
* Entrust servicing of the automatic transmission to qualified mechanics.
* Regular maintenance will help extend the life of the transmission and keep your vehicle running smoothly.
