GENERAL DESCRIPTION
AUTOMATIC TRANSMISSION23A-7
ELECTRONICALLY-CONTROLLED SYSTEM
.
INVECS-II
When in drive ("D" range), the new automatic transmission
employs an innovative shift schedule to provide a high level
of comfort and "easy driving style" that matches all driving
conditions as well as the driver's driving style.
INVECS-II features "Optimum Shift Control," which provides
shift timing the average driver perceives to be the optimum
timing under any road conditions. "Adaptive Shift Control"
adjusts shift timing to match the driving habits and prefer-
ences of individual drivers.
.
INVECS-II Sports Mode Automatic Transmission
A further development of the INVECS-II automatic transmis-
sion, incorporating a sports mode that enables quasi-manual
gear shifts. When the gear shift lever is pushed sideways fronm
the "D" position to the sports mode position, the driver can use
it to make gear selections manually. The sports mode has the
following features.
In contrast to the automatic "D" range, the sports mode
does not perform automatic upshifts. Thus, the engine can
be driven fully into its red zone.
For more rapid gear shifting, it is possible to shift directly
from 4th gear to 2nd gear, therby skipping a gear.
When the vehicle decelerates and stops, the system auto-
maticaly shifts down to 1st gear for conveinience when the
vehicle starts moving again. Further, 2nd gear can be
selected with the vehicle stationary, so standing starts can
be made in 2nd gear on slippery surfaces.

HOW TO INITIALIZE A/T LEARNING VALUEM1231022600121
AIM
The use of EEPROM has enabled the A/T learned
value to be retained even after the battery terminals
are disconnected. However, the learned value should
be initialized if the A/T assembly, the engine assem-
bly, the valve body assembly or the solenoid valves
are replaced. The initialization procedure is as
below:
INITIALIZATION PROCEDURE
1. Shift the selector lever to the P range and turn the
ignition switch to the LOCK (OFF) position. Then,
connect the MUT-III to the diagnosis connector.
2. Initialize the learned value on the initialization
screen.
3. After this initialization, make the system learn the
idling in accordance with "Learning procedure for
idling in MPI engine" (Refer to GROUP 00

Precautions before Service 00-22).
