ABSTRACT:
A diagnostic system is provided for responding to a fault condition in a transmission having an electronic control including diagnostics for both electrical and mechanical failures, said diagnostics indicating the affected clutch and the type of failure. The diagnostic system includes a processor for selecting a first table of available gears in response to the affected clutch and a first subset of electrical and mechanical failure types being diagnosed and for selecting a second table of available gears in response to the affected clutch and a second subset of electrical and mechanical failure types being diagnosed.
