Speedometer in '99 Legacy 2.2 stops intermittently, and my transmission "hunts"
I have a '99 Legacy 30th Anniversary w/ 100K, that we bought from an old(er) lady who probably didn't notice this quirk. The speedometer stops working intermittently, and then starts working again. Also, the automatic transmission "hunts" from 3rd to 4th gear, sometimes downshifting and staying there until I release the accelerator pedal and press down again. My mileage sucks. Is this related to the speed sensors on the transmission?
