2004 Porsche Cayenne Question: problem in transmission

Have a good Porsche shop look at this, it sounds like the 3-4 shift solenoid or even an internal mechanical 3-4 shift component, speed sensor etc, is defective. http://repairpal.com/directory?address=20878&car_brand_names=Porsche - dandd
A coolant leak may develop at the thermostat housing, under the intake manifold. Our technicians tell us that revised parts are available to correct this concern.
