Abstract: A vehicle system includes an engine, a transmission including a torque converter, a clutch configured to selectably couple and decouple the torque converter, and a gearset, a selective catalytic reduction (SCR) exhaust aftertreatment system. An electronic control system may be operatively coupled with the engine, the electronically controllable clutch, and the SCR exhaust aftertreatment system. The electronic control system is configured to evaluate whether an SCR catalyst temperature satisfies at least one minimum temperature criterion, in response to the SCR catalyst temperature satisfying the minimum temperature criterion, permit a neutral at stop operation wherein the electronically controllable clutch is controlled to selectably decouple the torque converter and the one or more gears at least in part in response to the vehicle system being in a stopped state, and in response to the SCR catalyst temperature not satisfying the minimum temperature criterion, prevent the neutral at stop operation.

Abstract: A coolant diverter system and method of controlling coolant flow are provided. The coolant diverter system includes a coolant diverter body having a coolant inlet opening, a driveline retarder outlet opening and a bypass outlet opening. The coolant diverter system also includes a valve positioned in the coolant diverter body. The valve is configured in a first valve orientation to fluidly couple the coolant inlet opening to the driveline retarder outlet opening in isolation from the bypass outlet opening. The valve is configured in a second valve orientation to fluidly couple the coolant inlet opening to the driveline retarder outlet opening and the bypass outlet opening. The coolant diverter system also includes a valve controller configured to place the valve in the first valve orientation in response to activation of a driveline retarder coupled to the driveline retarder outlet opening for braking.
