ROAD TEST K ROAD TEST A road test is necessary to inspect for problems in the different gear ranges. If a range or function tar- b geted by the road test is found to have any problem, refer to the ELECTRONIC SYSTEM COMPONENT segment or the TRANSMISSION, OIL COOLER, DRIVE PLATE, and SHIFT MECHANISM segments of this section. Do the road test only when the ATF is 50-80°C (1 22-1 76°F). D-RANGE TEST Shift Point, Shift Pattern, and Shift Shock 1. Shift the selector lever to D range and select the Normal mode. 2. Accelerate the vehicle with half-and wide open throttle opening. 3. Verify that 1-2, 2-3, and 3-4 upshifts, downshifts, and lockup are obtained. The shift points must be as shown in the D range (Normal) shift diagram. Note There is fourth gear is any of the following conditions. A The cruise control is operating, and there is an 8kmIh (5 mph} difference between the preset cruise speed and the vehicle speed. B The SET or RESUME switch is ON. There is no lockup when water temperature is below 50°C (1 22°F) or in the throttle valve closed posi- tion. 4. Check the upshifts for shift shock or slippage in the same manner. 5. While driving in overdrive, shift the selector lever to S range and verify that 4-3 downshift immediately occurs, then decelerate and verify that engine braking effect is felt in only third gear and 2nd gears.
