Abstract
A vehicle includes a transmission having a first neutral with a first combination of engaged clutches and a second neutral with a second combination of engaged clutches. The first neutral has more engaged clutches than the second. A controller is programmed to, in response to a request to shift from a drive gear to the first neutral and a clutch of the drive gear being failed-on, shift to the second neutral.
