I just pulled out my transmission dipstick yesterday and the filler tube came out with it! This is a common problem, so common that O'Reilley's had one in stock. It was a real pain to replace it, and the Dorman-brand replacement didn't fit exactly right. It didn't fully seat into the transmission, but the seal is 3/4" long and it doesn't seem to be leaking.Check for a crack in the weld area where your dipstick tube is welded to the mounting bracket that goes down to the head. I have seen them crack there, or the spot welds pull apart, and when hot, will shoot oil all over that area of the engine.
