I have a 2015 435ix auto. Will this work for both front diff and rear? How about transfer case? Im aware I have to suck out the rear. How much fluid is need for front, transfer and rear case after drain/extract?
Yes, 3 to 4 bottles are needed, 2 for the front and 2 for the rear. Fill capacity is around 1.5 liters for each differential. Please note the rear differential does not have a drain plug so we recommend using FCP-B3300000 in order to drain as much fluid as possible. For the transfer case you'll want to use a fluid known as TF0870, part number 83222409710.
