Yes folks we did miss this one. In our defense the belt noise didn't start until the customer came to pick the vehicle up after a pretty heavy downpour.
Joy is absolutely correct. During the time we had the vehicle to recheck the transmission, we could not duplicate the problem Joy described and the transmission was operating properly. When computerized engines or transmissions act up and do not store any error codes it is extremely difficult to diagnose a problem if the condition can not be duplicated.
