TOYOTA CAMRY V20 1986 Service Information

ROAD TEST (A140L)
NOTICE: Perform the test at norrnal operating fluid tem-
perature (122 ± 176°F or 50 ± 80°C).
1. D RANGE TEST
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±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
(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
Accumulator 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.

A140E)AT±46

2. 2 RANGE TEST
Shift into the .2 range and, while driving with the accel-
erator pedal held constantly at the full throttle valve
opening position, check on the following points.
(a) Check to see that the 1 ± 2 up±shift takes place and
that the shift point conforms to it shown on the auto-
matic shift schedule. (See page AT±49) (f) Check for the lock±up mechanism.
(1) Drive in D range, O/D gear, at a steady speed
(lock±up ON) of about 70 km/h (43 mph).
(2) Lightly depress the accelerator pedal and check
that the engine rpm does. not change abruptly.
If there is a big jump in engine rpm, there is no
lock±up.
(b) While running in the 2 range and 2nd gear, re-
lease the accelerator pedal and check the en-
gine braking effect.
EVALUATION
If there is no engine braking effect:
Second coast brake is defective (d) While running in the D range, 2nd, 3rd and O/D
gears, check to see that the possible kick±
down vehicle speed limits for 2 ±1, 3 ±2 and
O/D ± 3 kickdowns conform to those indicated
on the automatic shift schedule. (See page
AT±49)
(e) Check for abnormal shock and slip at kick±down.
(c) Check for abnormal noise at acceleration and de-
celeration, and for shock at up±shift and down-
shift.

A140E)AT±47

(b) While running in the L range, release the accelerator
pedal and check the engine braking effect.
EVALUATION
If there is no engine braking effect:
wFirst and reverse brake is defective
5. P RANGE TEST
Stop the vehicle on a gradient (more than 5
°) and after
shifting into the P range, release the parking brake.
Then check to see that the parking lock pawl holds the ve-
hicle in place.
4. R RANGE TEST
Shift into the R range and, while starting at full throttle,
check for slipping. 3. L RANGE TEST
(a) While running in the L range, check to see that there
is no up±shift to 2nd gear.
(c) Check for abnormal noise during acceleration
and deceleration.

A140E)AT±48

*O/D main switch OFF
HINT:
(1) In the 2 and L ranges, ail stages lock±up is OFF.
(2) In the following cases, the lock±up will be released regardless of the lock±up pattern.
When the throttle is completely closed.
When the brake light switch is ON.
*1 3 ± O/D up±shift point with closed throttle valve is at 32 ± 45 km/h (20 ± 28 mph).
*2 Lock±up ºONº' point with closed throttle valve is at 64 ± 73 km/h (40 ± 45 mph).
*3 Lock±up ºOFFº point with closed throttle valve is at 60 ± 68 km/h (37 ± 42 mph).
*4 O/D ±3 down±shift is possible up to maximum speed.
