RUNNING TEST
NOTE:
•
Be sure to confirm safety on the road when conducting the running test.
•
Make sure that the fluid temperature is in a normal running condition (70 - 80 °C).
1. Î range test
(1) Move off the vehicle with the shift lever set to the Î range. Check to see if upshift and downshift
take place between the 1st gear and the 2nd gear; between the 2nd gear and the 3rd gear; and be-
tween the 3rd gear and the 4th gear (overdrive). Also, check to see if each shift point conforms to
the specified value. Furthermore, check that there is no abnormal shock and slipping, etc.
(2) While driving the vehicle with the shift lever set to the Î range and the transmission in the 4th gear
(overdrive), 3rd gear, and 2nd gear, respectively, perform the kick-down operation. At this time,
check to see if kick-down takes place from the 4th gear (overdrive) to the 3rd gear, from the 3rd
gear to the 2nd gear; and from the 2nd gear to the 1st gear. Also, check to see if the vehicle speed
range during which kick-down is possible conforms to the specified value. Furthermore, check that
there is no abnormal shock or slipping, etc.
(3) When the overdrive switch is turned OFF while driving the vehicle in the 4th gear (overdrive), ensure
that the downshift from the 4th gear (overdrive) to the 3rd gear takes place.
2. x range test
(1) Move off the vehicle with the shift lever set to the x range. Check to see if upshift and downshift
take place between the 1st gear and the 2nd gear. Also, check to see if each shift point conforms to
the specified value. Furthermore, check that there is no abnormal shock and slipping, etc.
(2) Move off the vehicle with the shift lever set to the x range. At this time, ensure that upshift from the
1st gear to the 2nd gear takes place and that no upshift to the 3rd gear will take place.
(3) While driving the vehicle with the shift lever set to the x range and the transmission in the 2nd gear,
perform the kick-down operation. Check to see if kick-down takes place from the 2nd gear to the 1st
gear. Also, check to see if the vehicle speed range during which kick-down is possible conforms to
the specified value. Furthermore, check that there is no abnormal shock and slipping, etc.
(4) When the shift lever is shifted to the x range while driving the vehicle with the shift lever set to the
Î range and the transmission in the 3rd gear, check that downshift from the 3rd gear to the 2nd
gear takes place and engine brake is applied. Also, check to see if the shift point conforms to the
specified value.
3. Ò range test
(1) Move off the vehicle with the shift lever set to the Ò range. At this time, ensure that no upshift to the
2nd gear will take place.
(2) When the shift lever is shifted to the Ò range while driving the vehicle with the shift lever set to the
Î range and the transmission in the 3rd gear, check that downshifts from the 3rd gear / the 2nd
gear / the 1st gear take place and engine brake is applied. Also, check to see if the shift point
conforms to the specified value.
