Road Test

ROAD TEST
Perform road tests using "Symptom Chart" under Diagnosis By Symptom.

"P" POSITION
1. Place selector lever in "P" position and start the engine. Stop the engine and repeat the procedure in all positions, including "N" position.
2. Stop vehicle on a slight upgrade and place selector lever in "P" position. Release parking brake to make sure vehicle remains locked.

"R" POSITION
1. Manually move selector lever from "P" or "R", and note shift quality.
2. Drive vehicle in reverse long enough to detect slippage or other abnormalities.

"N" POSITION
1. Manually move selector lever from "R" and "D" to "N" and note shift quality.
2. Release parking brake with selector lever in "N" position. Lightly depress accelerator pedal to make sure vehicle does not move. (When vehicle is new or soon after clutches have been replaced, vehicle may move slightly. This is not a problem.)

"D" POSITION





1. Manually shift selector lever from "N" to "D" position, and note shift quality.
2. Using the shift schedule as a reference, drive vehicle in "D" position. Record, on Symptom Chart, respective vehicle speeds at which up-shifting and down-shifting occur. These speeds are to be read at three different throttle positions (light, half and full), respectively. Also determine the timing at which shocks are encountered during shifting and which clutches are engaged.
3. Determine, whether lock-up properly occurs while driving vehicle in proper gear position and at proper speeds.





4. Check to determine if shifting to overdrive gear cannot be made while overdrive control switch is OFF.
5. Drive vehicle at 65 to 80 km/h (40 to 50 MPH) with half to light throttle position (D3 position). Fully depress accelerator pedal to make sure transmission downshifts from 3rd to 2nd gear.
6. Drive vehicle at 35 to 45 km/h (22 to 28 MPH) with half to light throttle position (D2 position). Fully depress accelerator pedal to make sure transmission downshifts from 2nd to 1st gear.

"2" POSITION
1. Shift to "2" position and make sure vehicle starts in 1st gear.
2. Increase vehicle speed to make sure transmission upshifts from 1st to 2nd gear.
3. Further increase vehicle speed. Make sure transmission does not upshift to 3rd gear.
4. Drive vehicle at 35 to 45 km/h (22 to 28 MPH) with throttle at half to light position [2 (2) position]. Fully depress accelerator pedal to make sure transmission downshifts from 2nd to 1st gear.
5. Drive vehicle at idle in "2" position to make sure that transmission downshifts to 1st gear.
6. Move selector lever to "D" position and drive vehicle at 40 to 50 km/h (25 to 31 MPH). Then, move selector lever to "2" position to make sure transmission downshifts to 2nd gear.

"1" POSITION
1. Place selector lever in "1" position and accelerate. Make sure transmission does not shift from 1st to 2nd gear although vehicle speed increases.
2. While driving vehicle in "1" position, release accelerator pedal to make sure that engine compression acts as a brake.
3. Place selector lever in "D" or "2" position and drive vehicle at 20 to 30 km/h (12 to 19 MPH). Then move selector lever to "1" position to make sure transmission downshifts to 1st gear.
