| PC Solenoid 4 | B | No PSI flow to gauge |
| PC Solenoid 5 | F | No PSI flow to gauge |
| Shift Solenoid 1 | H | Full PSI flow to gauge |
| Shift Solenoid 2 | D | No PSI flow to gauge |
| TCC PC Solenoid | E | No PSI flow to gauge |
NOTE:
With the key on engine off (KOEO), the TCM will normally cycle some of the transmission solenoids On and Off to facilitate keeping the ports and solenoids clean and free of debris. This dither function is a normal activity and will cause the valves to cycle open and closed quickly when the TCM is powered up. This can cause the psi gage to flicker high and low as the valves open and close. This may cause some air to exit the ports where the psi gage is not connected as those solenoids cycle on and off.
Drain the TCM of excess transmission fluid before attaching to test block and use caution when attaching air to test block air inlet.
