Have you rechecked the fluid level? A code check should tell you if there are any transmission codes.

Yes I just did the code check say nothing wrong with the transmission.do the cars have any sensors on them?

Yes. there is the speed sensor it tells the ECM and the TCM vehicle speed, gear selector switch that tells the ECM and the TCM what gear you have selected, a number of solenoids that switch the gears when commanded from the TCM. So you need to find out if the TCM is actually commanding the shift solenoids to go from reverse too drive or any other gear. Do you have access to a "live data" scanner, if so you actually see the commands being given, and where to go from there.

No I don't have access to DAT .do you no ware the ECM and the TCM located on the car.

TCM is right of the glove box under the kick panel, any way that is what the book says. ECM is under the hood.
