>>F<< PTJ CASE <3.8L> INSTALLATION
The drive shaft joint use special grease. Do not mix old
and new or different types of grease.
After applying the specified grease to the PTJ case, insert the
drive shaft and apply grease again.
Specified grease: Repair kit grease
Amount to use <3.8L>: 220
10 g (7.8 0.3 ounces)
NOTE: The grease in the repair kit should be divided in half for
use, respectively, at the joint and inside the boot.

GENERAL DESCRIPTION
AUTOMATIC TRANSMISSION23A-8
FEATURES
OPTIMUM SHIFT CONTROL
1. The shift patterns found satisfying by the typical driver for all
ranges of driving are stored in the computer's memory. The
computer uses this data to analyze road conditions and the
driver's style of operation, and then outputs the optimal shift
patterns stored in its memory to best match the conditions.
2. We introduce the latest control technologies with an innova-
tive new algorithm called the "neural network" that works to
imitate the decision-making processes of the human brain.
The neural network links a wide variety of input data regard-
ing road and operating conditions, and instantly makes
accurate shift control decisions.
.
ADAPTIVE SHIFT CONTROL
1. The computer learns the driving habits and pref-
erences of each individual driver by processing
driving data on engine output, tyre load, foot
brake operation, etc. It then uses this data to
adjust shift timing to best suit the driver's style.2. If the computer determines from the driving pat-
terns that the driver is one who enjoys a relaxed,
unhurried style, it adjusts timing to execute
up-shifts at a lower engine speed to provide a
smooth, quiet ride. On the other hand, if the com-
puter determines the driver to prefer a sporty ride,
it adjusts timing to shift up at a higher engine
speed to provide more powerful response.
