Abstract
A controller may cause, in a lubrication oil warm-up mode of a transmission, the transmission to operate in a stall mode that transfers heat to transmission oil for the transmission. The transmission oil may be diverted to a lubrication oil heater to heat the lubrication oil using the transmission oil. The controller may cause the transmission to disengage the stall mode and to engage a park mode, to pause the lubrication oil warm-up mode. The controller may cause the transmission to operate in the stall mode, to resume the lubrication oil warm-up mode, after the pause duration.
