DIAGNOSTIC
TRANSMISSION FLUID PRESSURE
The quality of gear changing and the useful life of
the
clutch/brake
section
of
the
automatic
transmission
depend
on
correct
fluid
pressure
adj ustment.
Special Tool B.Vi. 466-07 must be used for this
function.
CHECKING
• The fluid
pressure must be checked with
the
transmission hot (80°C) during a road test only (the
fluid pressure varies with the temperature).
• Check
the
fluid
level
in
the
automatic
transmission. (See page F1-5 and F1-6)
• Make sure that the engine is correctly adjusted.
• Connect pressure gauge B.Vi. 466-07 (before using
the apparatus, set the pressure gauge to zero).
• Drive a few miles to allow
the oil to reach
approximately
80°C.
• Move the selector level to 2nd gear "Hold".
• Depress the accelerator
pedal completely
and
brake at the same time to stabilize speed at 50
mph (80-km/h) and read off the value on the
pressure gauge.
• The correct value should be 4.6 bars.
ADJUSTING
• Remove lock plate (2) and turn the capsule. The
pressure is increased by turning
the
capsule
clockwise.
NOTE:
2 notches
=
approximately
0.1 bars.
