1997 Doge Ram 1500 4x4, overdrive stays locked in at 45mph, but then cuts in and out from 50-70pmh. Need some advice.
Overdrive is on because I am in a higher gear on the highway, but overdrive does not stay locked. Also, is there a means to flush (clean and dissolve deposits) the trans with maybe kerosene or some other fluid? I need my overdrive to stay locked in.
