Harsh, erratic or delayed shifting (2017–present)
ModerateOwners have reported clunky, jerky or delayed shifts, and several class actions over 10R80-equipped vehicles have been filed, with mixed results; some were dismissed or narrowed. Ford service information notes the transmission’s adaptive strategy can produce firmer shifts while it relearns after a reset, and many cases are addressed with software updates.[3][4][2]
