Does the BMW 3 Series Transmission Fluid Need to Be Replaced?
1 Answers
BMW 3 Series transmission fluid needs to be replaced. Here are the relevant details about replacing transmission fluid: 1. Owners should replace the transmission fluid promptly after driving 80,000-120,000 kilometers. 2. Because transmission fluid oxidizes under high temperature and high pressure conditions, the fluid deteriorates, reducing its cleaning, lubrication, and cooling functions, so timely replacement is necessary. 3. When driving, if symptoms such as sluggish acceleration, jerky gear shifts, or poor shifting smoothness occur, consider replacing the transmission fluid. 4. When replacing the transmission fluid, you can loosen the oil pan bolt and let the transmission fluid drain out by gravity.
