Description

Gear Sel€stion
The shift lever has six positions: @ pARK, E REVERSE, E NEUTRAL, E DR|VE, g SECOND, and El LOW.
Staning is possible only in E and E positions through the use of a slid6-type, neutrafsafety switch.
Automrtic Transaxle {A/T} Gear Position Indicltor
The A-lT gear position indicator in the instrument panel shows which gear has been selected without having to look downat the console.

Front wheels locked; park pawl engaged with the park gear on the driven pulley shaft. The startclutch and the forward clutch released.
Reverse; reverse brake engaged.
Neutral; the start clutch and the forward clutch released.
General driving; the transmission automatically adjusts to keep the engine at the best speed fordriving conditions.
For rapid accelsration at highway speeds; the transmission shifts into a lower range of ratios forbetter acceleration and increased engine braking.
For engine braking and power for climbinO; the transmission shifts into the lowest range of theralros.

Description
Electronic Control System ('99 - 00 Modelsl (cont'dl
Grade Logic Control System
How it works:
The PcM compares actual driving conditions with memorized driving conditions. based on the input from the vehiclespeed sensor, the throttle position sensor, the manifold absolute pressure sensor, the engine coolant temperature sensor,the brake switch signal, and the shift lever position signal, to control shifting while the vehicle is ascending or descendinga slope.
Ascending Control
When the PCM determines that the vehicle is climbing a hill in E position, the system selects the most suitable shiftschedule (pulley ratio) according to the magnitude of a gradient. so the vehicle can run smooth and have more powerwhen needed. There are three ascending modes with different shift schedules according to the magnitude ot a gradient inthe PCM.
Descending Control
when the PCM determines that the vehicle is going down a hill in E position. the system selects the most suitable shiftschedule (pulley ratio) according to the magnitude of a gradient. This, in combinstion with engine braking, achievessmooth driving when the vehicle is descending, There are three descending modes with different shift schedules accord-ing to the magnitude of a gradient in the PCM.
