The transmission dipstick in my wife's Dart (360/904) leaks like a sieve, we replaced the O-ring twice and it hasn't helped. Could it be something else, or is the ring just misplacing during installation. Has anyone else had this problem and how did you fix it, e.g. some type of sealer on the tube. Thanks for any help, this is driving me nuts.
