AUTOMATIC TRANSAXLE

3. If the computer determines that the driver tends 

to apply the brakes often on a descending road-
way, it adjusts timing to down shift sooner so that 
engine braking is more effectively applied. Con-
versely, if the computer determines that the driver 
does not brake much while driving downhill, it 
delays downshifting to minimize the effect of 
engine braking.

NOTE: Within 2 -to- 3 and 3 -to- 4 movement ranges, the PCM adjusts shift points according to the driving 
conditions by memorizing the accelerator pedal stroke and braking timing.
