Why can't CVT use a circulation machine for oil change?
1 Answers
Cvt using a circulation machine for oil change will increase the amount of transmission oil used, thereby raising the cost, so it is not recommended to use a circulation machine for CVT oil change. Here is more information about transmission oil change: 1. One method is the traditional gravity method to drain the oil, which has the same principle as changing engine oil. It involves loosening the transmission's drain screw to release the oil and then refilling with new oil. 2. Another method uses a circulation machine to change automatic transmission oil, mainly utilizing the machine's pressure to dynamically replace the oil in the torque converter's lubrication pipe and cooling pipe. 3. When using a circulation machine for oil change, the oil pump continuously pumps new oil into the transmission while the suction pipe continuously draws out the old oil from the transmission's drain port. By controlling the amount of oil added and drained to be equal, the total amount of oil inside the transmission is maintained. This process requires a large amount of transmission oil, resulting in higher costs.
