Manual Gear Range Selection

Upshifts in the manual gear ranges are controlled by the shift solenoids.

Perform the following tests by accelerating at 10-15° TP Sensor.

Manual Third (D3)
With the vehicle stopped, move the gear selector to D3 and accelerate in order to observe:
- 1-2 shift
- 2-3 shift

Manual Second (D2)
1. With the vehicle stopped, move the gear selector to the D2 position and accelerate in order to observe if the transmission starts and remains in second gear.
2. Accelerate to 40 km/h (35 mph) and observe the following:
- The 2-3 shift does not occur.
- The TCC does not apply.

Manual First (D1)
1. With the vehicle stopped, move the gear selector to D1.
2. Accelerate to 32 km/h (20 mph).
3. Observe the following conditions:
- No upshifts occur.
- The TCC does not apply.
- You can upshift out of first at the fuel cut-off.

Reverse
With the engine stopped, move the gear selector to R and slowly accelerate in order to observe is the 1-2 and the 2-3 shift solenoids are on.

Use a scan tool in order to see if any transmission trouble codes have been set. Refer to "TROUBLE CODES" diagnosis and repair the vehicle as directed. After repairing the vehicle, perform the hoist test and verify that the code has not set again.

If the transmission is not performing wall and no trouble codes have been set, there may be an intermittent condition, Check all electrical connections for damage or a loose fit. Some scan tools have a snapshot test which can help catch an intermittent condition that doesn't occur long enough to set a code.

You may want to read "ELECTRONIC COMPONENT DIAGNOSIS" in order to become familiar with the transmission conditions caused by transmission electrical malfunctions.

If no trouble codes have been set and the condition is suspected to be hydraulic, take the vehicle on a road test.
