1986 TOYOTA CAMRY V20 torque

OPERATION
Power from the engine transmitted to the input shaft via the torque converter is then trans-
mitted to the planetary gears by the operation of the clutch.
By operation of the brake and one±way clutch, either the planetary carrier or the planetary sun
gear are immobilized, altering the speed of revolution of the. planetary gear unit.
Shift change is carried out by altering the combination of clutch and brake operation.
Each clutch and brake operates by hydraulic pressure; gear position is decided according to
the throttle opening angle and vehicle speed, and shift change automatically occurs.
The conditions of operation for each gear position are shown on the following illustrations:

5. INSPECT AND ADJUST SHIFT CABLE
When shifting the shift lever from the N position to oth-
er positions, check that the lever can be shifted
smoothly and accurately to each position and that the
position indicator correctly indicates the position.
If the indicator is not aligned with the correct position,
carry out the following adjustment procedures.
(a) Loosen the swivel nut on manual shift lever.
(b) Push the manual lever fully toward the right side of the
vehicle.
(c) Return the lever two notches to NEUTRAL position.
(d) Set the shift lever to N.
(e) While holding the lever lightly toward the R range
side, tighten the swivel nut.
6. ADJUST NEUTRAL START SWITCH
If the engine will start with the shift selector in any
range other than N or P range, adjustment is required.
(a) Loosen the neutral start switch bolts and set the shift
selector to the N range.
(b) Align the groove and neutral basic line.
(c) Hold in position and tighten the bolts.
Torque: 55 kg±cm (48 in.±Ib, 5.4 N±m)
7. INSPECT IDLE SPEED (N RANGE)
Idle speed: 700 rpm 4. INSPECT AND ADJUST THROTTLE CABLE
(a) Depress the accelerator pedal all the way and check that the
throttle valve opens fully.
HINT: If the valve does not open fully, adjust the accelerator
link.
(b) Fully depress the accelerator pedal.
(c) Loosen the adjustment nuts.
(d) Adjust the outer cable so that the distance between the end
of the boot and stopper on the cable is the standard.
Standard boot and cable stopper distance:
0± 1 mm 10±0.04 in.)
(e) Tighten the adjusting nuts.
(f ) Recheck the adjustments.

ROAD TEST (A140E)
NOTICE: Perform the test at normal operating fluid
temperature (122 ± 176°F or 50 ± 84°C). .
1. D RANGE TEST IN NORM AND PWR PATTERN
RANGES
Shift into the D range and hold the accelerator pedal
constant at the full throttle valve opening position.
Check the following:
(a) 1±2, 2±3 and 3±O/D up±shifts should take place, and
shift points should conform to those shown in the au-
tomatic shift schedule. (See page AT±49)
Conduct a test under both Normal and Power patterns.
HINT:
There is no O/D up±shift when coolant temperature is
below 122
°F (50°C).
There is no lock±up when the vehicle speed is 10 km/h (6
mph) less than the set cruise control speed.
EVALUATION
(1) If there is no 1 ± 2 up±shift:
wNo. 2 solenoid is stuck
w1±2 shift valve is stuck
(2) If there is no 2 ± 3 up±shift:
w No. 1 solenoid is stuck
w2±3 shift valve is stuck
(3) If there is no 3 ± O/D up±shift:
w3±O/D shift valve is stuck
(4) If the shift point is defective:
wThrottle valve, 1±2 shift valve, 2±3 .shift valve, 3±
wO/D shift valve etc., are defective
(5) If the lock±up is defective:
wLock±up solenoid is stuck
wLock±up relay valve is stuck
(b) In the same manner, check the shock and slip at the 1
±2, 2 ± 3 and 3 ± O/D up±shifts.
EVALUATION
If the shock is excessive:
wLine pressure is too high
wAccumulator is defective
wCheck ball is defective
(c) Run at the D range lock±up or O/D gear and check for
abnormal noise and vibration.
HINT: The check for the cause of abnormal noise and
vibration must be make with extreme care as it could
also be due to loss of balance in the drive shaft, tire,
torque converter, etc.

constant at the full throttle valve opening position.
Check the following:
(a) 1±2, 2±3 and 3±0ID up±shifts should take place, and
shift points should conform to those shown in the au-
tomatic shift schedule. (See page AT±49)
EVALUATION
(1) If there is no 1 ±2 up±shift:
wGovernor valve is defective
w 1±2 shift valve is stuck
(2) if there is no 2 ±3 up±shift:
w 2±3 shift valve is stuck .
(3) If there is no 3 ± O/D up±shift:
w3±O/D shift valve is stuck
wO/D solenoid is defective
(4) If the shift point is defective:
wThrottle cable is out±of±adjustment
wThrottle valve, 1±2 shift valve, 2±3 shift valve, 3±
O/D shift valve etc., are defective

abnormal noise and vibration.
HINT: The check for the cause of abnormal noise and
vibration must be make with extreme care as it could
also be due to loss of balance in the drive shaft, tire,
torque converter, etc.
