TROUBLE-SHOOTING AND DIAGNOSES
Road Test
2 Using the shift schedule as a reference, drive
vehicle in
"D" range Record, on symptom
chart, respective vehicle speeds
at which up-
shifting and downshifting occur These speeds
are to be read at several different intake mani-
fold vacuum levels
(see the chart on the next
page). Also determine the timing
at which
shocks are encountered during shifting and
which clutches
are engaged
Drive on different throttle condirtom

3. Check to determine if shifting speed changes
when accelerator pedal
is depressed slowly and
when
it is depressed quickly (E4N71B trans-
mission models)
4 Check to determine if shifting to overdrive gear
cannot be made while power shift switch
(E4N71B transmission) is"0N" or
O.D. cancel
switch (4N71
B transmission) is "OFF".

5. When vehicle is being driven in the 65 to 85
km/h (40 to 53 MPH) range in "Ds" range at
half to light throttle position, fully depress ac-
celerator pedal to make sure
it downshifts from
3rd to 2nd
gear.
6. When vehicle is being driven in the 25 to 35
km/h (16 to 22 MPH) ("D," range) at half to
light throttle position, fully depress accelerator
pedal to make sure
it downshifts from 2nd to
1 st gear
"2" RANGE
1 While vehicle is being driven in "2" range,
make sure that
it does not shift into 1st or 3rd
gear, despite speed changes.
2 Shift control lever to "D" range and allow
vehicle to operate
at 40 to 50 km/h (25 to 31
MPH) Then, shift to "2" range to make sure
it downshifts to 2nd gear.
"1" RANGE
1. Shift control lever to "1" range and allow
vehicle to run. Ensure
that it does not upshift
from 1st to 2nd gear although vehicle speed
increases
2 While vehicle is being driven in "1" range,
release accelerator pedal
to make sure that
engine compression acts
as a brake
3. Shift control lever to "D" or "2" range and
allow vehicle to run
at 20 to 30 km/h (12 to 19
MPH). Then, shift control lever to "1" range to
make sure the downshift to 1st gear is made.
