Tranny

Sounds like you have transmission issues. I do not know the mileage on your vehicle or if and when you had your last transmission service, fluid and filter change (usually every 30K). I recommend that you take the vehicle to your local dealership of transmission shop and have them road test and diagnosis your vehicle.
