How to Change Transmission Oil for Magotan?
3 Answers
Here are the steps to change transmission oil for Magotan: 1. First add transmission cleaner into the gearbox to decompose the oil film on gears as much as possible, then lift the vehicle. 2. Shift between D and R gears, and drive for 5-10 minutes. 3. After these two steps, the automatic transmission will be cleaned, so now drain the old oil. Here is some information about transmission: 1. Unlike engine oil change, automatic transmission fluid replacement requires specialized equipment to completely remove old lubricant and other residues. 2. 49% of automatic transmission fluid cannot be drained by atmospheric pressure, and the remaining oil will mix with sludge and impurities in valve body, torque converter and cooling lines, which may cause internal passage blockage if not thoroughly cleaned.
I've changed the transmission fluid for my Magotan myself. You need to prepare the specialized tools and genuine fluid beforehand. It's best to operate when the engine is warm, as the old fluid flows better. Remove the engine undercover, locate the drain plug on the oil pan, and remember to place an oil drain pan underneath. After the fluid has completely drained, remove the oil pan to replace the filter screen - this step is crucial but often overlooked. When reassembling, make sure to use a new gasket, then pour in the new fluid through the filler port. After filling, start the engine and cycle through each gear to circulate the fluid. Finally, check the fluid level using the dipstick to ensure it's in the middle. The whole process takes about two hours. Beginners are advised to have an assistant keep an eye on things, as too much or too little fluid will affect shifting smoothness.
Last time at the specialist workshop, I noticed the technician was very meticulous when changing the transmission fluid for a Magotan. They first warmed up the car for ten minutes, then lifted the vehicle to extract the old fluid using professional equipment. When removing the oil pan, they paid special attention to the screw sequence, mentioning that Volkswagen's oil pans are prone to deformation. While replacing the filter, they checked the metal debris on the magnet, as this can reflect transmission wear. The new fluid was slowly injected using a pressure tank to avoid creating air bubbles. Most crucially, they used a diagnostic computer to reset the transmission data at the end; otherwise, the shifting logic could become erratic. The entire process took one and a half hours, and it's recommended every 60,000 kilometers, especially for vehicles frequently stuck in traffic.
