ROAD TEST [5R55S]

id0513c1248900

Warning
•  When performing a road test, be aware of other vehicles, people, and impediments to avoid an accident.
Note
•  Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.
•  When the legal speed limit must be exceeded, use a chassis dynamometer instead of performing a road test.

Road Test Preparation

1.  Inspect the engine coolant level. (See COOLING SYSTEM SERVICE WARNINGS [WL-C, WE-C].) (See ENGINE COOLANT LEVEL INSPECTION [WL-C, WE-C].)

2.  Inspect the engine oil level. (See ENGINE OIL LEVEL INSPECTION [WL-C, WE-C].)

3.  Inspect the ATF level. (See AUTOMATIC TRANSMISSION FLUID (ATF) INSPECTION [5R55S].)

4.  Inspect the idle speed. (See ENGINE TUNE-UP [WL-C, WE-C].)


Shift Point Road Test

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

1.  Bring up the engine and transmission 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.

4.  Stop the vehicle.

5.  Depress O/D OFF switch to activate D range and repeat Step 3.

6.  The transmission will make all upshifts except 4-5, and the torque converter clutch application should occur above 46 km/h {29 mph}.

7.  Press the accelerator pedal to the floor, wide open throttle (WOT). The transmission should shift from 3GR to 2GR or 3GR to 1GR depending on vehicle speed, and the torque converter clutch should release.

8.  With the vehicle speed above 48 km/h {30 mph}, move the transmission range selector lever from D range to 1 range and release the accelerator pedal. The transmission should immediately downshift to 3GR. When the vehicle speed drops below 32 km/h {20 mph}, the transmission should downshift into 1st gear.

9.  If the transmission 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 [5R55S].)
