Checking and topping up transmission oils

To keep the working parts lubricated, the gearboxes and final drive units have their own oil supply. Most of the time, the oil used is a type known as hypoid oil, and only the recommended grade should be used to top it off. A level check is required, and topping up is probably unnecessary unless there is a leak, which is usually obvious.

When checking transmission oil levels, a dentist’s mirror can be extremely useful. Automobiles with automatic transmissions typically have a lubricant dipstick under the hood, which is frequently checked while the engine is running.
