this question isn't for an X5, but rather e60LCI. The e60 forum isn't as active as this one. which is why i figured i post my question here.

i have a 2009 528i with a hole in the transmission cooler attached to this radiator. i'm planning on changing it this weekend. my question is do i need to add transmission fluid to the transmission after i replaced the cooler?
