How many liters of transmission fluid are needed for a Magotan transmission fluid change?
2 Answers
When changing the transmission fluid for a Magotan, manual fluid change (gravity drain) requires four to six liters; using a fluid exchange machine requires approximately nine to twelve liters. Functions of transmission fluid: Reduce friction, minimize wear, control clutch friction and synchronizer performance; bear loads (low-speed high torque, vibration loads), dissipate heat, reduce vibration and noise, remove contaminants from gear meshing (cleaning function); prevent corrosion, pitting, and surface metal stripping, isolate metal surfaces to prevent direct metal-to-metal contact. Risks of not changing transmission fluid for a long time: Damage to the transmission's shift control mechanism; abnormal wear of gears and clutch plates inside the transmission; affect the normal operation of the transmission, leading to damage to the transmission valve body. Methods for changing transmission fluid are as follows: Loosen the drain screw at the bottom of the transmission to drain the fluid before refilling. Remove the transmission oil pan directly to drain and refill the fluid: this method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a circulation machine to change automatic transmission fluid: dynamic fluid exchange with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission.
I've been repairing Volkswagen cars for many years, especially the transmission oil change for the Magotan. For manual transmissions, about 3 to 4 liters is usually enough, but most Magotans come with automatic or DSG transmissions. The gravity method typically requires 4 to 6 liters of oil, while a machine flush might exceed 7 liters due to thermal expansion and contraction of the oil. During the process, it's important to add new oil slowly to avoid air bubbles. After refilling, a test drive is necessary to check if the gear shifts smoothly. The exact amount depends on the model year—for example, in my experience, pre-2015 Magotans have a smaller oil pan and require about 4 liters, while newer models may need over 5 liters. The best interval for an oil change is every 60,000 to 80,000 kilometers. Too little oil can cause wear, and too much is not only wasteful but also unsafe. I recommend using OEM-certified oil; avoid off-brand products that can shorten the transmission's lifespan. DIY changes are too troublesome—I've seen cases where users didn't get the oil level right, leading to transmission noise and costly repairs. So, it's better to find a reliable shop for peace of mind.
