the garage said it was very clean like it had just been done.the car has just done 200miles and not had the problem once got in it this morring and it did it after acouple of miles

Expert:  mike_a_mechanic replied 4 years ago.
Ok. What you are describing is the valve body inside of the gearbox is loosing pressure,the most common reason for this is one of the solenoids is starting to fail. The problem is for this gearbox the valve body has to be replaced as the solenoids are not sold separately The first step needs to be the vehicle needs to be connected to a gearbox scan tool and driven with will monitor the pressure readings..

Not sure what that is most scan tools now have a program specifically for the gear box. You will likely need a dealer or a garage that specializes in working on gearboxes.
