When I come to a stop at a traffic light, or any reason, then go to accelerate there is nothing there for a few seconds then the transmission slams onto gear with a sharp jolt that rattles my dogs, and myself, quite a bit. This doesn't happen all the time. About 50% of the time. Contact me.

The number one reason for this to occur is low transmission fluid levels, also check the fluid condition as well. Here is a generic guide to help you step by step with instructions in the diagrams below to show you how on your car:
