People on a Volvo forum say not to remove the transmission dipstick tube from the pan because it will always leak after putting it back, and instead drop the pan with the tube attached. I tried that but these wasn't enough room so I ended up removing it anyway. Would putting a sealant on the thread help with leaks on this type of flair seal? I don't think so as fluid that gets past the flare would just between the tube and the nut, right?
