A fault tolerant method of gear selection which initiates a gear selection search (32, 44) in response to a gear upshift (30) or downshift (42) requirement in an attempt to locate a gear that, if used, would result in an engine speed between both upper and lower engine speed limits (36, 38, 40, 52). The search progresses from the lowest to the highest gear in the case of an upshift requirement and from the highest to the lowest gear in the case of a downshift requirement. <IMAGE> <IMAGE> |
