I have A 1997 Dodge Dakota, 318, With a 5 Speed. So basically what my problem is, when I am going down the road at any speed, in any gear, when I let off the gas theres a bad jerk forward, and theres a grinding noise at the same time when it jerks coming from underneath the truck. Also when I hit the gas again, theres another jerk forward and the same small grinding noise. Some times it makes the same noise when I press on the clutch. It never grinds when im coasting down the road or anything like that. I have no idea what the problem is, and I need help!
