At Low Fluid Temperature
WARNING: This page is about a different variant/trim than selected.
- A/T fluid viscosity and frictional characteristics of the clutch facing change with A/T fluid temperature. Clutch engaging or band-contacting pressure is compensated for, according to A/T fluid temperature, to stabilize shifting quality.
- The line pressure is reduced below 60°C (140°F) to prevent shifting shock due to high viscosity of A/T fluid when temperature is low.
- Line pressure is increased to a maximum irrespective of the throttle opening when A/T fluid temperature drops to -10°C (14°F). This pressure rise is adopted to prevent a delay in clutch and brake operation due to extreme drop of A/T fluid viscosity at low temperature.
