Why dowes my 2003 caravan hesitate at start up to go into drive

Start by checking transmission fluid. Check in Park at normal operating temperature, engine running, parked on level surface. Also have a good look at the fluid on the dipstick, needs to be nice and red/light red and not have a burnt odor. If it's a brown tint it needs to be changed, but a drain and fill only not a flush. Hopefully that's all it is, they don't have to lose much to cause your symptoms, as little as 1/2 quart low will do that.

Will do, thank you for your fast reply. I was just at the dealership where I purchased it last week, and they "topped off" my fluids. It was in for an oil change ( supplied free for life, came with the purchase )..I guess they don't really look for issues, and I did not mention it. I will take a look at the color..thanks again!
