Got to our site, backed in and put it in neutral, noisey again but sounded different. Stayed 3 days and no noise when we left or got home.
I inspected the tranny oil and it didn't look too healthy. Maybe even a slight burning smell.
My question is, what tranny fluid should I use. The manual sez Transynd. I highly doubt in our little town I'll find it on the shelf. I need it by Friday b4 a 12hr drive.
Soooooo, what are you guys using? Thx
Or, do I have a different issue? Thx again..
Odd thing when I started it after registration, the winshield wiper controls on the steering wheel didn't work. When I went to turn on the auto leaving system, it wouldn't. I let it sit for a few minutes and everything worked. ..
Ok, none of your issues are probably related. The windshield wipers, the leveling system, and the transmission have nothing to do with one another, unless, you weren’t running the coach while leveling (low battery).
So you apparently have up to three separate issues, or four. The most important one, being the transmission.
Have you checked the fluid level? Your’s is pretty new, but the tranny, or filter could have some manufacturing debris (the death of any tranny is microscopic debris).
IF, and haven’t done it yet, I’d add a synthetic fluid in my transmission. But, drain it out first, and change the filter.
However, troubleshooting something like this over the Internet is like being blind. Could it possibly have been your power steering unit to make a noise and not your transmission? Who knows we weren’t there to help you figure it out.
It’s probably something unrelated to this, but it’s maintenance anyway. At least you will remove one variable for the dilemma...
