2003 Dodge Caravan - Trans

I have a 2003 dodge caravan when i first turn it on it will catch geer but as soon as you take foot of of the gas peddle, it will will slip into neutral like and i turn the car off and it will go

With it off you are saving gas, quit complaining!!!

I really have no idea of what you might be asking.
