Shift-Hold Control
When negotiating winding roads, the throttle is suddenly released and the brakes are applied, as is the case when
decelerating at the entrance of a curve, shift-hold control keeps the transmission in its current (lower) ratio as it
negotiates the corner and accelerates out.
When the vehicle is driven aggressively on a winding road, the PCM will extend the engagement time of 3rd gear and
4th gear to prevent the transmission from frequently shifting between 3rd, 4th, and 5th gears. This allows the driver to
have more control for both acceleration and deceleration.
The PCM monitors the average change in the vehicle speed and throttle over time. When these values exceed those
for normal driving conditions, the up-shift from 3rd to 4th gear and 4th to 5th gear is delayed. This gives more control
over power, and the engine braking when the driver is driving aggressively around winding roads. The transmission
will resume the normal up-shift pattern after the PCM determines that normal driving has resumed.
