Summary
This Preliminary information communicates that a customer may bring a vehicle in with a complaint that the engine rpm increased and/or the vehicle downshifted for no reason. The dealer is instructed to test drive the vehicle and check for codes. If no cause of the concern is found and it cannot be duplicated the dealer technician is instructed to review operation of the tap shift operation in the owner's manual. The technician is then instructed to drive the vehicle with the customer and downshift the vehicle using temporary tap shift mode to demonstrate this feature to the customer and see if this is what the customer is experiencing. If the customer states that this is what they are experiencing the dealer is advised to educate the customer on the tap shift operation.
