Manual Gear Range Selection

NOTE: The shift solenoids control the upshifts in the manual gear ranges. Perform the following tests by accelerating at 10% TP ANGLE.

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

MANUAL SECOND (2)
1. With the vehicle stopped, move the gear selector to Manual Second (2) and accelerate in order to observe the 1-2 shift.
2. Accelerate to 40 km/h (25 mph) and observe the following conditions:
- The 2-3 shift does not occur.
- The TCC does not apply.

MANUAL FIRST (1)
With the vehicle stopped, move the gear selector to Manual First (1). Accelerate to 32 km/h (20 mph) and observe the following conditions:
- No upshifts occur.
- The TCC does not apply.

REVERSE (R)
With the vehicle stopped, move the gear selector to R and slowly accelerate in order to observe the following conditions:
- The 1-2 Shift Solenoid valve is On.
- The 2-3 Shift Solenoid valve is Off.

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

If the transmission is still not performing well but no trouble codes have 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 does not occur long enough to set a code.

Refer to ELECTRONIC COMPONENT DESCRIPTION in order to become familiar with transmission conditions caused by transmission electrical malfunctions.

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