I have a 96 v6 automatic and it decided it didn't want to go any further yesterday. I was driving into town on the highway and I went to accelerate and all I heard was a grinding noise each time I hit the gas so I just coasted and got on to the axis road shut it down waited a second and tried to start it back up and the starter just spun so I didn't try it again called someone towed it to the house put it on ramps motor and trans are not seized up any ideas what it could be
