Road Test Procedures
ROAD TESTRoad Test Preparation
1. Check and correct the engine coolant, engine oil, and ATF levels as necessary before testing.
2. Warm up the engine thoroughly to raise the ATF temperature to operating level (60 - 70°C (140 - 158°F)).
3. Check the idle speed and ignition timing in P position.

D Range Test
D Range (O/D OFF Switch OFF)
1. Shift the selector lever to D range.
2. Accelerate the vehicle to half throttle and wide open throttle.
3. Verify that 1-2, 2-3, and 3-4 upshifts and downshifts are obtained. The shift points must be as shown in the table below.
4. Drive the vehicle in fourth, third, and second gears and verify that kick down occurs for 4 -> 3, 4 -> 2, 3 -> 2, 3 -> 1, 2 -> 1, and that the shift points are as shown in the table below.
5. Decelerate the vehicle and verify that engine braking effect is felt in fourth and third gears.
NOTE: There is torque converter clutch non-operation in the following conditions.
1. The engine coolant temperature is below 72°C (162°F).
2. The closed throttle position switch is on.
3. The brake switch is on.
6. Drive the vehicle and verify that torque converter clutch operation is obtained.
D Range (O/D OFF Switch ON)
1. Turn the O/D OFF switch from OFF to ON.
2. Accelerate the vehicle to half throttle and wide open throttle, and verify that 1-2 and 2-3 upshifts and downshifts are obtained. The shift points must be as shown in the table below.
3. Drive the vehicle in third and second gears and verify that kickdown occurs for 3 -> 2, 3 -> 1, 2 -> 1, and that the shift points are as shown in the table below.
4. Decelerate the vehicle and verify that engine braking effect is felt in third gear.

2 Range Test
1. Shift the selector lever to 2 range.
2. Accelerate the vehicle to half throttle and wide open throttle, and verify that second gear is held.
3. Decelerate the vehicle and verify that engine braking effect is felt.

1 Range Test
1. Shift the selector lever to 1 range.
2. Accelerate the vehicle to half throttle and wide open throttle, and verify that first gear is held.
3. Decelerate the vehicle and verify that engine braking effect is felt.
