SHIFT CONTROL OUTLINE [SJ6A-EL]
• Based on the shift diagram, shift solenoids A, B, C, D, E, F, and G are controlled according to the vehicle speed
and the throttle opening angle, and the shift control of the transmission is performed.
• When certain conditions are met, the TCM selects a shift mode suitable to the driving conditions and
automatically switches to the mode to perform smooth shifting.
POWER MODE
• The POWER MODE in which the shift point is set higher than the normal shift point is automatically
selected when certain conditions are met so that high-engine speed high-output conditions are available.
DOWN SLOPE MODE
• While the vehicle is being driven on a down slope, the TCM determines that the vehicle is being driven on a
down slope based on the signals and output engine speed from the PCM, and switches the driving mode to
the DOWN SLOPE MODE. Due to this, load to the brake is reduced.
UP SLOPE MODE
• When the vehicle is climbing a slope, the TCM determines that the vehicle is being driven on an up slope
based on the signals and output engine speed from the PCM, and switches the driving mode to the UP
SLOPE MODE. Due to this, reduction in traction is prevented.
