Car will go in reverse then when shifted into D nothing will not move. But when I shift into L car it will drive and go through gears and once I get up to 45 or 50 MPH I can shift up to D and hit highway speeds no problem.

It sounds like the pressure control switch is not working but we should run the codes first, you can get a code scanner from Amazon for about $20.00.

Here is a guide/video to show you how:

Here is how you can change the pressure control switch out int he images below. Check out the diagrams (below). Please let us know what happens.

Thank you for the info. I have a scanner and I'll check to see if there are any codes. I didn't check before since the check engine light didn't come on or any other warning lights. I appreciate the diagrams but can this procedure be done without taking the transmission out or dismantling have of the under carriage?

This is a difficult job to do unfortunately. I have seen people drop the cradle and tip the engine and transmission downward to get the pan off of the side, you will need a top engine support like this. Check out the diagrams (below). Please let us know what happens.
