In this blog, we would like to explain what exactly the role of a truck gearbox is, and why it is crucial to stay on top of its maintenance.

A truck gearbox is what changes the gear of an engine, thereby transferring the engine’s power to the wheels with the purpose of moving the vehicle ahead. For a vehicle with manual gearbox, you’ll start in first gear, gain some momentum/speed, then shift to second gear and build more speed etc. With an automatic gearbox, the same process is applied with the assistance of a torque converter, which automates the acceleration and gearing process. 

The truck gearbox plays a pivotal role for your vehicle. While the description of what a transmission does is simple, it contains hundreds of components working together to move your vehicle, the gearbox fluid inside enables cooling and lubrication, helping transmit force and pressure and also preventing build-up. By changing the gearbox fluid on a regular basis, the fluid stays clean and will keep the transmission running smoothly. Old and/or dirty gearbox fluid can lead to problems such as loss of acceleration, difficulties in gear shifting, and in worst-case scenarios total transmission failure. 

As stated, it is important to properly maintain your truck gearbox, and it is easy and stress-free at Gearbox Centre. Feel free to give us a call anytime, and our friendly staff will be readily available to assist you.
