Abstract
Featured is are methods and systems for bedding-in an automatic transmission of a vehicle prior to delivery of the vehicle to an end customer. Such a bedding-in method is performed so as to reduce the occurrence of shifting problems or concerns occurring during the initial stages of ownership of the vehicle. More particularly, such a bedding-in method includes providing an automatic transmission having a controller that is configured to measure and learn about powertrain variation(s) and configured to adapt one or more operational parameters associated with shifting of the automatic transmission. Such a method also includes operating the vehicle according to a predetermined protocol before the vehicle reaches an end customer. Such a protocol being established so the transmission controller can learn about powertrain variations and adapt operation of the transmission to minimize effects on shifting of the transmission.
