My mom's car is having problems. Basically if you try to accelerate too fast from being stopped you hear a clunk and it will only work in gears 2-3. Gear 1 and overdrive do not work after this happens. However it doesnt do this if it is not rapidly accelerated. The CEL has been on for awhile and has the codes P0442, P0456, P0715, P1529. After the car sits for awhile it works normally unless you rapidly accelerate it from a stop. Anyone knows whats going on? Obviously its an auto tranny

 

You look up those codes yet?
