A/T Road Test
|1.||Warm up the engine to normal operating temperature (the radiator fan comes on).|
|2.||Apply the parking brake, and block both rear wheels.|
|3.||Start the engine, then shift to the D position while pressing the brake pedal. Press the accelerator pedal, and release it suddenly. The engine should not stall.|
|4.||Repeat step 3 in all shift lever positions.|
|5.||Connect the HDS to the DLC (A), and go to the A/T data list.|
NOTE: If the HDS does not communicate with the PCM, troubleshoot the DLC circuit.
|6.||Test-drive the vehicle on a flat road in the D position. Check for abnormal noise and clutch slippage. While driving, check that the shift points occur at the proper speeds by monitoring the accelerator pedal position sensor voltage with the HDS and comparing your shift point speeds and voltage to those in the table. (The accelerator pedal position sensor voltage represents the throttle opening.)|
|7.||Check the engine braking applied when:|
|8.||For 7-position transmission: Shift to the 1 position, accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage. Upshifts should not occur in this position.|
|9.||For 7-position transmission: Shift to the 2 position, accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage. Upshifts and downshifts should not occur in this position.|
|10.||Shift to the R position, accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage.|
|11.||Park the vehicle on a slope (about 16 degrees), apply the brake, and shift into the P position. Release the brake; the vehicle should not move.|
NOTE: Always use the brake to hold the vehicle, when stopped on an incline in gear. Depending on the grade of the incline, the vehicle could roll backwards if the brake is released.
