Road Test
NOTE: Warm up the engine to operating temperature (the radiator fan comes on).
1. Apply parking brake and block the wheels. Start the engine, then shift to @ position while depressing the brake pedal-
Depress the accelerator pedal, and release it suddenly. The engine should not stall.
2. Repeat same test in E position.
3. Test drive the vehicle on a flat road in the @ position. Check that the shift points occur at approximate speeds shown.
Also check for abnormal noise and clutch slippage.
NOTE: Throttle position sensor voltage represents the throttle opening.
-1. Remove the TCM (see page 14-52).-2. Set the digital multimeter to check voltage between 84 (+) terminal and A13 or A26 (-) terminal for the throttle posi-
tion sensor.

4. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th, then shitt from E position to E position.
The vehicle should immediately begin slowing down from engine braking.
CAUTION: Do noi shitt lrom I or $ position to E or E position 8t speeds over l0o mph (160 km/h); you may
damage the transmission.
5. Check for abnormal noise and clutch slippage in the following positions,
E {1st Gear} Position-1. Accelerate from a stop at fullthrottle. Check that there is no abnormal noise or clutch slippage.-2. Upshifts should not occur with the shift lever in this position.
E (2nd Gear) Position-1. Accelerate from a stop atfull throttle. Check that there is noabnormal noiseorclutch slippage.-2. Upshifts and downshifts should not occur with the shift lever in this position.
E (Reverse) Position
Accelerate from a stop at tull throttle, and check for abnormal noise and clutch slippage.
6. Test in E (Parking) Position
Park vehicle on slope {app.ox. 16'}, apply the parking brake, and shift into E position. Release the brake; the vehicle
should not move.

Pressure Testing
a While testing, be careJulot the rotating front wheels.
a Make sule litts, iacks, and safety stands are placed
properly (see section 1).
CAUTION: Befoie testing, be sure the transmission fluid
is filled to the proper level.
'1. Raise the vehicle {see section 'll.
2. Warm up the engine (the radiator fan comes on),
then stop the engine and connect a tachometer.
3. Connect the special tool to each inspection hole(s).
TOROUE: 18 N.m l1-8 kgt.m, 13lbf.ftl
CAUTION: Connect the A/T pressure gauge secure-
ly, be sure not to allow dust and olher foreign pani-
cles to enter the inspection hole.

4. Start the engine, and measure the respective pres
sures as follows.
a Line Pressure

a Clutch Low/High Pressure
a Throttle B Pressure
5. Install a new sealing washer and the sealing bolt in
the inspection hole and tighten to the specified
torque.

5. Slowly move the throttle linkage to increase engine
rpm until pressure is indicated on the A/T pressure
gauge.
Then release the throttle linkage, allowing the en-
gine to return to an idle, and measure the pressure
reading.
6. With the engine idling. lift the throttle controldrum
up approximately 'l12 of its possible travel and in-
crease the engine rpm until pressure is indicated
on the gauge, then measure the highest pressure
reading obtained.
