How to check the transmission oil, how to look at the transmission dipstick

Oil maintenance is a very important part of car maintenance. Transmission oil is a very important oil for cars. You should always check the condition of the transmission oil, including the amount and quality of the transmission oil, and gear shifting. How to check the tank oil is the first question.

The inspection method of the transmission oil is different from that of the engine oil. The engine oil is inspected in a cold state, and the transmission oil needs to be run at idle speed. Warm up the oil to about 50°C and then hold the gear lever in each gear for 2 seconds. To enable the torque converter and all shifts to be executedYuanThe parts are filled with hydraulic oil, and then hung in the parking gear. Then the oil volume can be judged from the traces of the transmission oil on the transmission dipstick. The normal oil level should be between the highest and the lowest line of the dipstick. How do you look at the transmission dipstick?

Pull out the transmission oil dipstick from the oil filler pipe. First, you must wipe it clean, then insert the oil filler pipe and pull it out to check the oil level on the oil dipstick. If it is a gearbox in a cold state, the oil level should be near the lower limit of the dipstick; if it is a gearbox in a hot state, the oil level should be near the upper limit of the dipstick.

The oil level of the transmission oil fluctuates under different conditions. This is because the viscosity of the hydraulic oil is high at low temperatures, and more transmission oil adheres to the internal parts during operation. The oil level is low, while at high temperatures. Transmission oil has a low viscosity and is easy to flow back to the oil pan, so the oil level is relatively high. If the oil level is too low, add suitable transmission oil from the filler pipe until the oil level meets the standard.
