ROAD TEST[LA4AX-EL (CD4E)]

id051708802200

Note

• Drive the vehicle in a safe manner according to traffic conditions and observe all traffic laws.

Road Test Preparation

1. Inspect the engine coolant level. (See COOLING SYSTEM SERVICE WARNINGS[AJ (3.0L Duratec)].) (See ENGINE COOLANT LEVEL INSPECTION[AJ (3.0L Duratec)].)

2. Inspect the engine oil level. (See ENGINE OIL LEVEL INSPECTION[AJ (3.0L Duratec)].)

3. Inspect the ATF level. (See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION[LA4AX-EL (CD4E)].)

4. Inspect the ignition timing. (See ENGINE TUNE-UP[AJ (3.0L Duratec)].)

5. Inspect the idle speed. (See ENGINE TUNE-UP[AJ (3.0L Duratec)].)

Shift Point Road Test

Note

• This test verifies that the shift control system is operating correctly.

1. Bring up the engine and transaxle to normal operating temperature.

2. Shift the selector lever to the D range.

3. Apply minimum throttle and observe speeds at which up-shift occurs and the torque converter engages.

Caution

• Do not exceed posted speed limits when performing this test.

Shift speed (Reference)

Throttle position	O/D position shift	Vehicle speed (km/h {mph})
Closed	4—3	58 {36}
	3—2	29 {18}
	2—1	11 {7}
Minimum monitor PID minimum TP volt 1.25	1—2	21—26 {13—16}
	2—3	37—43 {23—26}
	3—4	67—74 {42—46}
Wide open	1—2	72 {45}
	2—3	132 {82}
	3—4	—

4. Coasting 2-1 down-shift procedure: accelerate the vehicle from a stop to 19—24 km/h {12—15 mph}.

5. Release the accelerator, and coast down or lightly brake the vehicle.

• The coast down-shift may be nearly imperceptible to the driver.

6. Move the vehicle into D (4GR).

7. Depress the O/D OFF switch.

• The transaxle should down-shift to 3GR.

8. Release the accelerator pedal.

• The engine braking should occur. The TCC should disengage and then reapply.

9. Depress the accelerator pedal to floor.

• The transaxle should shift from 3rd to 2nd, or 3rd to 1st, depending on vehicle speed.

10. With the vehicle in the D range while travelling at 80 km/h {50 mph} or more at less than half throttle, shift the selector lever from D range to the manual 2 range and release the accelerator pedal.

• The transaxle should immediately down-shift into 2nd.

11. With the vehicle remaining in the manual 2 range, shift the selector lever into manual 1 range and release the accelerator pedal.

• The transaxle should down-shift into 1st while travelling at 48—56 km/h {28—32 mph} or less.

12. If the transaxle fails to up-shift/down-shift or the torque converter does not apply and release, inspect according to “SYMPTOM TROUBLESHOOTING”. (See SYMPTOM TROUBLESHOOTING ITEM TABLE[LA4AX-EL (CD4E)].)
