Drive High Mode Engine On: Notes
WARNING: This page is about a different variant/trim than selected.
When the gear selector lever is in the Drive (D) position and the HPCM determines that operating conditions are appropriate, the internal combustion engine (ICE) is started, the main fluid pump provides hydraulic fluid pressure. If the transmission is operating in extended range fixed gear ratio and the HPCM determines that operating conditions are appropriate for a shift to extended range high, the following changes would occur to the transmission's hydraulic and electrical systems.
