I have a 1995 mustang with about 200,000 miles. When I shift into gear from park, it has been kicking back or forward harder than usual. Could this be a sign that my transmission is about to go out? Also sometimes hear a clunking after stopping, then begin accelerating. Does that mean there’s slack in my UV joint? I took it on the interstate and went up to 80mph and no shuddering or wobbling. Driving 300 miles and back and want to make sure I won’t be stranded somewhere. Thank you!!
