“LEAKING” Automatic Transmission Dipstick Tube

Probably a bent or cracked tube. If you can't find a replacement, it might be RTV time. Everything needs to be REAL clean though. That's the tough part without draining the transmission. Jack up the passenger side as high as you can. Wipe down any oil residue and spray with carb cleaner to finish the job. Pull the tube and clean it the same way. Coat the tube and O-ring with some RTV of the proper type for oily surfaces, and reinstall. Add a bit more around the seam where the tube and case meet. Let dry and cure according to specs on the RTV tube. I like the black, but, there are others. and people have their favorites. Some just don't seem to hold up in oil sealing applications.
