How to maintain the interior of the gearbox

The internal maintenance of the gearbox requires cleaning, replacing with new lubricating oil, checking whether the fasteners of the gearbox assembly are loose, and whether the joints and oil seals are leaking. As one of the important components of a car, the gearbox still has a significant impact on the car. In fact, the maintenance of the gearbox, like the engine, requires regular oil changes, which can to some extent extend the service life of the vehicle.

Manual transmission: if the transmission uses mineral oil Gear oil, the transmission oil needs to be replaced every 3 years or 60000 km. If using synthetic oil, the transmission oil should be checked regularly, as long as the oil is not faulty, it can be used continuously.

Automatic transmission: Most brands of automatic transmission models require a transmission oil change every 4 years or 60000 to 80000 kilometers.

CVT transmission: Due to its simple structure and the use of synthetic transmission oil, the replacement interval is slightly longer than that of an automatic transmission, and it is more suitable to replace it every 80000-100000 kilometers. Due to the fact that there are two types of dual clutches: dry and wet, the maintenance methods for transmissions are also different. The dry Dual-clutch transmission does not need oil change and maintenance, while the wet Dual-clutch transmission needs to change the oil and filter element every 60000 km like the automatic transmission.

Does frequent shifting of the transmission in N gear harm the transmission

This will damage the transmission. There is a certain gap between the parking pawl and the parking gear in the automatic transmission. When the driver puts into P gear and releases the brake pedal, due to the small rotation angle of the transmission shaft, the car will have a small vibration until the two gears engage with each other before it comes to a complete standstill.

Gearbox wear is not caused by shifting in most cases, but by a lack of maintenance. The gearbox, like the engine, is one of the three major components of a car. Car owners who frequently drive should know that the oil needs to be changed regularly. In fact, the transmission oil also needs to be replaced. Even those transmissions that are referred to as’ lifetime maintenance free ‘still require regular replacement.

High speed automatic cars usually cannot enter R gear. Even if the gear knob is pushed to the “R” position between D and R, there is still N position, so it actually stops and slides in N position. Of course, I dare not risk my life trying all models, and I cannot rule out that some models have exciting settings, but at low speeds, it’s different. The current automatic transmission operation is simple, unlike manual transmission, which requires attention to fuel distribution coordination.
