TEST TWO A-SELECTOR IN OD (4th Gear)
NOTE:
This test checks the underdrive clutch hydraulic circuit as well as the shift schedule.
- Attach gauge to the underdrive clutch tap.
- Move selector lever to the (OD) position.
- Allow wheels to rotate freely and increase throttle opening to achieve an indicated speed of 40 mph.
- Underdrive clutch pressure should read below 5 psi. If not, then either the solenoid assembly or PCM/TCM is at fault.
