These cars trannys are electrical. I would check the grounds. I have a 97 Lesable which had a bad ground by the battery on the fender well. It was causing all sorts of malfunctions to the point of stalling. With the age of your car I would look for something like this. Is your cooling fan running?

hello do you think it`s a sensor or is the head gasket golng, what get`s me is that the throttle doesn`t kick down until you let the car cool down
