Use The Fluid Recommended by the Vehicle Manufacturer
It is very important for the vehicle fleet to avoid costly downtimes that can cause breakdowns. One of the most expensive breakdowns is the breakdown of the transmission in a semi-truck. In order to avoid such a failure, it is necessary to perform semi-truck transmission fluid changes.
The fluid in the gearbox is responsible for reducing friction between moving parts and for cooling the heat generated during operation. Without this fluid, parts would wear out faster and overheat, which automatically leads to transmission failure. Old oil loses its properties over time, leading to slow or rough gear changes. In semi-trucks, the precise control of the gearbox is very important and therefore this fluid must be changed after a certain number of kilometers driven.

The fluid in the gearbox also serves to collect metal particles and other impurities. If you use the same fluid for a long time and if you do not change it, all these particles can cause internal damage to parts and various blockages that cause poor quality transmission work and can cause serious failures. It is very important to perform regular oil changes in the gearbox, as this prevents breakdowns that cause very expensive repairs, and sometimes the entire gearbox needs to be replaced. Regular oil changes are much cheaper than these scenarios.
If you want your semi-truck to not spend a lot of time off the road, then you need to perform regular semi-truck transmission fluid changes. This means that you will have a longer operating time of the truck, which will bring you more profit, and the money invested in changing the oil is almost insignificant compared to replacing parts in the transmission or replacing the entire transmission.
