Live in huntsville,al and bought a 02 ranger swb,2.3 manual. Always onky bought 3.o so i know very little about 4cyl. I need several things and i think first is a tranmission. My littl truck runs great til it warms uo then it grinds going into 3rd and only then. Told its syro gears in transmission and that is what i know least about. Any advice. Dont know if i can swap tranny myself and suggestions ?
