Ascending Control {37 Modol}
When the PCM determines that the vehicle is climbing a hill in E] and E positions, the system extends the engagement
area of 2nd g€ar and 3rd gear to prevent the transmission from frequently shifting between 2nd and 3rd gears, and
between 3rd and 4th gears, so the vehicle can run smooth and have more power when needed.
NOTE:
. Shift schedules stored in ths PCM between 2nd and 3rd gears, and between 3rd and 4th gears. enable the PCM's fuzzy
logic to automatically select the most suitable gear according to the magnitude of 8 gradient.
t Fuzzy logic is a form of artificial intslligence that lets computers respond to changing conditions much like a human
mind would.

Asconding Conirol ('98 - 00 Mod.ls)
When the PCM determines that the vohicle is climbing a hill in E] and E positions ('98 model), and in E] position ('99 -
00 models), the system extends the engagement srea of 2nd gear and 3rd gear to prevent the transmission from frequent-
ly shifting between 2nd and 3rd gears, and between 3rd and 4th gears, so the vehicle can run smooth and have more
power when needed.
NOTE: Shift schedulss stored in the PCM between 2nd and 3rd gears, and between 3rd and 4th gears, enable to selsct the
most suitable gear according to th6 magnitude of a gradi€nt.
