Park to Drive Buzz for Ford Explorer

Order Reprints

Some 2013-2014 Ford Explorer vehicles may exhibit a growl or buzz noise coming from the transmission that occurs when shifting from park to drive or park to reverse, most often after the vehicle has been parked and then re-started.

Identify the transmission build date on the transmission identification tag. Replace the main control valve body separator plate or main control assembly as required by the transmission build date.
