ROAD TEST
NOTE:
Perform the test at normal operation fluid temperature (50
– 80
C or 122 – 176F).
"D" RANGE TEST IN "NORMAL", AND "POWER"
PATTERN RANGES
Shift into the "D" range and hold the accelerator pedal constant
at the 50% and 100% throttle valve opening positions.
Push in one of the pattern selector buttons and check the
fol lowing:
1) 1-2, 2-3, 3-OD and lock-up, up-shifts should take place,
and shift points should conform to those shown in the
automatic shift diagram.
NOTE:
Drive the vehicle on level ground so as not to change to up
and down hill control.
EVALUATION
(1) If there is no 1
2 up-shift:
• No. 2 solenoid is stuck
• 1-2 shift valve is stuck
(2) If there is no 2
3 up-shift:
• No. 1 solenoid is stuck
• 2-3 shift valve is stuck
(3) If there is no 3
OD up-shift (throttle valve opening 1/2):
• No. 2 solenoid is stuck
• 3-4 shift valve is stuck
(4) If the shift point is defective:
Refer to
"TROUBLESHOOTING CHART" in this section.
(5) If the lock-up is defective:
Refer to
"TROUBLESHOOTING CHART" in this section.
2) In the same manner, check the shock and slip at the 1 2,
2
3 and 3 OD up-shifts.
EVALUATION
If the shock is excessive:
Refer to
"TROUBLESHOOTING CHART" in this section.

3) Run at "D" range lock-up or OD gear and check for
abnormal noise and vibration.
NOTE:
The check for the cause of abnormal noise and vibration
must be made with extreme care as it could also be due to
loss of balance in the propeller shaft, differential, the
torque converter, etc. or insufficient bending, rigidity, etc.
in the power train.
4) While running in "D" range, 2nd, 3rd gears and OD, check
to see that the possible kick-down vehicle speed limits for 2
1, 3 1, 3 2, OD 3 and OD 2 kick-downs
conform to those indicated on the automatic shift diagram.
5) Check for abnormal shock and slip at kick-down.
6) While running in "D" range, OD gear or "lock-up", shift to
"2" and "L" ranges and check the engine braking effect at
each of these ranges.
7) Also check to see that downshift is made from 3
2 or
from OD to 3 and then to 2 immediately and that 2
1
downshift point is within the limits shown in the diagram
when tested by releasing the accelerator pedal and shifting
into position of "L" while driving in the third gear or in
overdrive.
EVALUATION
(1) If there is no engine braking effect in the "2" range:
• Second coast (No. 1) brake is defective.
(2) If there is no engine braking effect in the "L" range:
• First and reverse (No. 3) brake is defective
(3) Also check to see that downshift is made from 3
2 or
from OD to 3 and then to 2 immediately and that 2
1
downshift point is within the limits shown in the diagram
when tested by releasing the accelerator pedal and shifting
into "L" position while driving in the third gear or in
overdrive.

"2" RANGE TEST
Shift into "2" range and, while driving with the accelerator pedal
held constantly at the specified point (throttle valve opening
50% and 100%), push in one of the pattern selectors (only for
4x4) and check on the following points.
1) At each of the above throttle openings, check to see that
the 1
2 up-shift takes place and that the shift points
conform to those shown on the automatic shift diagram.
NOTE:
There is no OD and no lock-up in the "2" range.
2) While running in the "2" range and 2nd gear, release the
accelerator pedal and check the engine's braking effect.
3) Check for 2
1 down-shift and abnormal noise at
acceleration and deceleration, and for shock at upshift and
down-shift.
"L" RANGE TEST
1) While running above 90 km/h (56 mph) in the "D" range,
release your foot from the accelerator pedal and shift into
the "L" range.
Then check to see that the 2
1 and 3 2 down-shift
occurs at the specified point shown on the automatic shift
diagram.
2) While running in the "L" range, check to see that there is no
up-shift to 2nd gear.
3) While running in the "L" range, release the accelerator
pedal and check the engine braking effect.
4) Check for abnormal noise during acceleration and
deceleration.
"R" RANGE TEST
Shift into the "R" range and, while starting at full throttle, check
for slipping.
"P" RANGE TEST
Stop the vehicle on a grade (more than 9%) and after shifting
into the "P" range, release the parking brake. Then check to
see that the parking lock pawl holds the vehicle in place.

TCM VOLTAGE CHECK
TCM voltage check is done to check for transmission and
transmission control module (TCM) problems which cannot be
detected by self-diagnosis.
Additionally, it serves as a back-up check for self-diagnosis.
Measure the voltage drop and make a continuity test for each
of the sensors, solenoids, and switches.
If the voltage is within the specified range and continuity exists,
that particular area of the TCM and automatic transmission
assembly is normal.
If voltage deviation or lack of continuity is discovered,
disconnect the applicable parts and check each of them
individually.
This will allow you to determine the trouble location (TCM,
automatic transmission unit, or another area of the vehicle).
Inspection Tool
Use a circuit tester to measure voltage and circuit continuity.
Inser t the test probes from the connector wiring side. TCM
terminals are extremely small.
Wrap a piece of thin wire around the probe of tester.
This will make measurement easier.
TCM Voltage Check Procedure
1. Remove the TCM.
2. Turn the ignition switch on. Do not start the engine.
3. Measure the voltage at the terminal. Refer to
the following
table for the specified voltage ranges.
