How many hours does it take to change transmission oil?
2 Answers
Changing transmission oil takes about 1 hour. The methods for changing transmission oil are: 1. Gravity replacement: After loosening the nut at the bottom of the oil pan, the transmission oil will automatically flow out from the oil hole; 2. Circulation machine replacement: Connect the transmission and the circulation machine through pipeline interfaces, and use new oil to push out the old oil. The maintenance methods for automatic transmission are: 1. Regularly change the transmission oil; 2. Frequently check the oil level; 3. Do not coast in neutral; 4. Avoid skipping gears when upshifting; 5. Do not force shifting into neutral; 6. Try to shorten the idling warm-up time; 7. Avoid gear grinding when shifting; 8. Clean the transmission.
Last time I went to change the transmission fluid, it took almost three hours because I drive an automatic car and they used the machine circulation method. The mechanic said they had to completely drain the old fluid before refilling with new oil, which required connecting to the machine for a slow circulation process that couldn't be rushed. During the process, they also had to remove the oil pan to clean the filter screen and check if the sealing gasket had aged. Manual transmission cars are faster - it can be done in just over an hour. I recommend making an appointment in advance and avoiding peak hours. When I went on a weekday morning, it was much less crowded. Also, don't try to save money by choosing cheap oil - the transmission is the heart of the car, and using the wrong oil can cause gear shift jerking or even damage.
