If the problem was a slow leak, YOUR dealer should have been able to find it. UV die and all... Plus there should have been trans fluid soiling things “down under”, and there would be signs of the fluid under the car wherever you son usually parks it. If there was no leak, that should be fairly easy to determine too...
This is reminding me I am due to check the trans fluid level of our ‘09 Outback. (It at least has a dipstick for trans fluid.) If the fluid is getting a little brownish, I’ll drain and refill, as I have lots of the fluid. With newer Outbacks (and many other vehicles) you have to get under the car and pull the fill plug and see if anything runs out. (What a dumb way to have to check a fluid level, IMO. It’s just asking for negligence!)
My “fun” this week is an old (and large) filling came out. It’s at the location of an old root canal job on a molar - back in my 40’s when I was incredibly busy and, really, not taking good care of my teeth — as I came to painfully regret with this one!
Well, that old work has suddenly failed, and, oh, golly, this hurts even more now. Even cool breath getting back there hurts. Anbesol helps only a little. Ditto for Tylenol or Ibuprofen. My current dentist can’t get me in until Sept. 24, so, I’m going to have an unpleasant couple weeks. :-(
I may get a dental mirror and see if wifey can do a better job with her small fingers of getting the Anbesol into the right spot.
Meanwhile, we are headed for a big warm-up. Hot and dry, probably for a couple weeks. Mid-90’s by this weekend. I’m surprised we don’t have a burn ban already. The garden has been finally doing great — I hope I can keep it that way! At least dew points stay below 65°F, so, evenings shouldn’t be to bad.
The dye step was the next diagnostic step. We didn’t have enough time to do that before they got back. He has street parking at his apartment, so he can’t usually see if there are leaks. His parking spot changes daily, but when it was in our driveway, there were no leaks.
He hasn’t had a problem since we got it back, so I really do suspect that the mechanic at the old dealership where he took it was at fault. They just won’t fess up.
