Manual Gear Range Selection

MANUAL GEAR RANGE SELECTION
The shift solenoid controls upshifts in manual gear ranges. Perform the following tests by accelerating at 10% TP sensor position.

Manual Third (3)
With the vehicle stopped, move 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 vehicle stopped, move 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 vehicle stopped, move 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 vehicle stopped, move gear selector to R and slowly accelerate in order to observe the following conditions:
- The 1-2 Shift Solenoid is ON.
- The 2-3 Shift Solenoid is OFF.

Use a Scan tool to see if any engine/transaxle trouble codes are set. Refer to "Diagnostic Trouble Codes" and repair the vehicle as directed. After repairing the vehicle, verify code did not set again.
If transaxle 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.
If no DTCs are set and the condition is suspected to be hydraulic, take vehicle on a road test.
