What does it mean to change transmission oil with a circulation machine?
1 Answers
Changing transmission oil with a circulation machine is a process that uses a machine to generate pressure and dynamically replace the automatic transmission fluid (ATF). The principle involves simultaneously extracting the old oil and injecting new oil, using pressure to push the old oil out with the new oil. Currently, there are two common methods for changing transmission oil: gravity oil change and circulation machine oil change. Traditional manual transmission oil changes only replace the oil in the transmission oil pan, leaving some ATF inside the transmission that cannot be removed. After replacement, the new oil mixes with the old oil, resulting in an incomplete change that does not fully serve the purpose of replacement.
