I just got my 2006 330i trans. fluid changed because the leaking sealing sleeve. I purchased 6 liters of lifeguard6. With oil pan down, i measured my old fluid is about 6 liters. I am able to pump 6 liters back in, but it looks like it can take more. Before I change fluid, the car was sitting in garage for 10 days or so. I just wondering... may be because the car has not be driven for 10 days, the more fluid can be drained + the amount fluid got leaked out from sealing sleeve.
After fluid changed, the car is run normal just as i have before. I am little worry about i am under fluild.
Anyone, should I purchase another liter to be safe?
