Abstract
When a vehicle driver selects reverse while a vehicle is moving forward, a transmission controller applies friction shift elements within the transmission to create a partial tie-up condition to decelerate the vehicle. Once the vehicle slows below a threshold speed, the controller engages a selectable one way brake and releases some of the friction shift elements to engage a reverse gear ratio.
