1991 Nissan Pick up Truck mileage: 70,000. During my drive to home, the transmission started to slip and within 1/2 mile, I had lost all power. The sound of engine is fine enough, but the vehicle acted like it was in neutral. when I reached home, I found transmission oil all over the ground. Does this mean my transmission has been totally ruined or is there a chance that something minor such as a hose or something like that has gone bad?
