Ways To Inspect And Maintain The Gearbox Of A Car

A car is more like a necessity than a luxury today. Owning a car comes with a commitment to regular upkeep. One of the most crucial automobile parts is the gearbox, and the transmission is its core mechanism. The system throws all that force down on the road so that wheels receive the proper torque and power for smooth driving. Excessive power can lead to the failure of the entire engine. Therefore, regular industrial gearbox maintenance is crucial to avoid costly repairs or, even worse, accidents due to mid-of-the-road engine failure. Here are essential factors to be paid proper attention-

  1.   Fluid Leakage

Car owners often feel the need to top off the oil sooner than they had expected. But in most cases, they avoid looking beneath to check whether there’s a leakage issue. When the gearbox is under extreme pressure, fluid leakage occurs and causes significant erosion of gear teeth and eventually leading to major cracks. It is important to fix leaky areas as soon as possible and get the gearbox inspected if there’s any significant damage.

  1.   Transmission Fluid Change

The car owners must follow the instructions in the car handbook if it says the transmission needs routine upkeep and fluid changes. Similar to engine oil, transmission fluid thickens and gets filthy over time, which affects lubrication. It will be challenging to shift gears if the gearbox isn’t properly lubricated, and dryness can eventually cause the gearbox to become stuck, suffer damage, or even fail.

  1.   Cleaning the Gearbox

It is vital to ensure that the gearbox is free of debris buildup. For optimum care, car owners consider using gear filters called breathers. In the gearbox, these breathers are strategically installed to stop water and dirt from entering. However, the problem of dirt accumulation still occurs. Therefore, it should be a primary responsibility to do routine industrial gearbox maintenance checks and get the gearbox cleaned. Besides the gearbox, debris can damage the oil and further destabilize the system.

  1.   Temperature Check

Car owners should monitor the temperature of the gearbox using an infrared gun. If there are any dramatic fluctuations, this can be an indication of a problem. For instance, using too sticky lubricant cause imbalanced friction between the grease levels and viscosity, leading to overheating.

  1.   Pan Gasket Inspection

The pan gasket is positioned between the transmission case and the transmission pan. It is a delicate rubber seal, and with time it may become worn and ruptured, allowing transmission fluid to leak. The pan gasket is quite simple to inspect, and if broken, it should be replaced by a specialist.


Even if car owners follow the warnings above, there’s still a possibility of gearbox damage. Every responsible car owner should take their vehicle for regular industrial gearbox maintenance for a complete inspection that includes vibration tests, shifting tests, and oil checks. Following the repair and replacements (if required), the owner will receive a detailed report on the car’s gearbox condition and upkeep tips. Although such maintenance can be pricey, this procedure saves hundreds of dollars in the long run!
