if you have any scan tool with a live data stream, you can watch the shift solenoids.
also you can watch the trans temp as well to see if it shows any problems. ( the trans temp sensor is in the pressure manifold.)
it will also show whether or not the computer is commanding a down shift back to low gear.
there are times that a electronic device can test good and work for a certain length of time, say like a car warming up to operating temp and quit working once the vehicle has gotten hot.
