What is the correct method for maintaining an automatic transmission?
2 Answers
Correct maintenance methods for automatic transmissions include: 1. Checking the automatic transmission fluid by testing its viscosity with fingers and replacing it if discolored or with a burnt smell; 2. Inspecting the manual gear selection mechanism, adjusting the linkage or cable connecting the gear lever to the manual valve so that the position of the manual handle corresponds to the spring clip position inside the automatic transmission; 3. Adjusting the brake band; 4. Checking the braking performance of the parking gear, and inspecting and repairing if there is no braking performance in the parking gear. The functions of the transmission are: 1. Changing the transmission ratio to meet the traction needs under different driving conditions, allowing the engine to operate under favorable conditions; 2. Enabling the vehicle to reverse; 3. Interrupting power transmission when the engine starts and idles, during gear shifting or parking, to stop power transmission to the drive wheels; 4. Engaging neutral gear to stop power output from the transmission when the clutch is engaged.
Regularly changing the automatic transmission fluid is very important. I do it every two years or every 40,000 kilometers, using the type of fluid recommended by the manufacturer, such as ATF-III or an equivalent specification. When checking the fluid level immediately after parking and turning off the engine, make sure the dipstick reading is between the upper and lower limits. Avoid sudden acceleration or towing heavy loads, as this can cause the transmission to overheat. During cold starts, warm up the car for a minute or two to stabilize the oil temperature before driving. Once, I delayed maintenance and experienced rough shifting, which later cost me over 5,000 yuan to repair—a big lesson. Also, avoid leaving the car in neutral for extended periods during daily driving, as this can lead to carbon buildup. The maintenance cost is not high, but it can extend the car's lifespan and save you from major repair expenses.
