Important:
• | Perform the road test following the sequence given. |
• | The throttle position and the habits of the driver will cause
the km/h (mph) shift points to vary. |
• | Compare the results of the road test with the Transaxle Shift
Speed Schedule. Use these results with the diagnosis information in this section
for the transaxle evaluation. |
• | This test should only be performed when traffic conditions and
road conditions permit. |
• | Observe all traffic and safety regulations. |
Drive and Reverse Engagement Test
- Turn the ignition switch to ON.
- Depress the brake pedal completely.
- Place the manual selector in the Park (P) range.
- Start the engine.
- Move the manual selector from the Park (P) range to the Reverse
(R) range.
- Observe the reverse engagement.
- Move the manual selector from the Reverse (R) range to the Drive
(D) range.
- Observe the drive engagement.
- Move the manual selector from the Drive (D) range to the Park
(P) range.
- Turn the ignition switch to the LOCK position.
- Verify that the following conditions exist:
• | The reverse engagement takes approximately 1.4 seconds
at the normal operating fluid temperature. |
• | Normal operating fluid temperature is 70-80°C (158-176°F). |
• | The drive engagement from the reverse engagement takes approximately
1.0 seconds. |
• | The reverse and the drive engagements should be immediate, but
not harsh. |
• | If the reverse and the drive engagements are slow to engage or seem
too harsh, refer to
Line Pressure Test

Upshifts Test
- Move the manual selector to the Drive (D) range.
- Steadily increase the throttle pressure, and accelerate the vehicle.
- Note the vehicle speeds and the shift points for the following
gears:
Use the following steps in order to perform the part throttle downshift
test:
Important: Before you perform the road test procedures, allow the fluid to reach
the normal operating temperature of 70-80°C (158-176°F).
- Operate the vehicle at the speeds of 35-45 km/h (22-28 mph)
- Verify that the manual selector is in the Drive (D) range.
- Quickly press the accelerator pedal. Press the pedal
to the half throttle position.
- Verify that the transaxle immediately downshifts to second gear.
Full Throttle Downshift Test
- Operate the vehicle at the speeds of 77-88 km/h (48-55 mph).
- Verify that the manual selector is in the Drive (D) range.
- Quickly press the accelerator pedal to the Wide Open Throttle
(WOT) position.
- Verify that the transaxle immediately downshifts to second gear.
Manual Downshift Test
- Move the manual selector to the Drive (D) selector.
- Operate the vehicle at 40 km/h (25 mph).
- Release the accelerator pedal.
- Move the manual selector to the Low (L) range.
- Verify the following operating conditions:
• | The transaxle downshifts immediately to first gear. |
• | The engine reduces the vehicles speed. |
Coastdown Downshift Test
- Verify the manual selector is in the Drive (D) position.
- Depress the accelerator pedal until the transaxle is in third
gear.
- Release the accelerator pedal.
- Lightly apply the brake pedal.
- Observe the vehicle speeds at points of downshifts.
Manual Third Gear (D) Range Selection Test
- Stop the vehicle.
- Move the manual selector to the Drive (D) range.
- Slowly accelerate the vehicle, and verify the following operating
conditions:
• | The transaxle upshifts from the first to the second gear. |
• | The transaxle upshifts from second gear to third gear. |
Manual Second (2) Range
- Stop the vehicle.
- Place the manual selector in the second range (2).
- Slowly accelerate the vehicle.
- Verify that the transaxle upshifts from the first to the second
gear.
- Accelerate to 40 km/h (25 mph).
- Verify that the transaxle does not upshift from second gear to
third gear.
Manual Low Test
- Stop the vehicle.
- Place the manual selector in the Low (L) range.
- Slowly accelerate the vehicle.
- Verify that the transaxle does not upshift from the first to the
second gear.
Reverse (R) Test
- Stop the vehicle.
- Place the manual selector in the Reverse (R) range.
- Slowly accelerate the vehicle.
- Verify that the vehicle operates in a rearward direction.
