I noticed coming back from camping last weekend my motorhome would downshift from 3rd to 2nd doing 50 mph and it wouldn't shift up to 3rd until I manually went down to 2nd and then back up to D and then it would kick up to 3rd. I've check the transmission fluid and it seems to be good level . I have noticed a hissing noise under the dash when I let off the brake. I have had trouble with mice in the coach and am wondering if those little s$&ts have chewed on something that has caused a vacuum issue? Anyone experience a hissing noise related to the brake peddle coming back up after use. It does stop hissing when peddle comes back up after I pressed on it.
