| 1 - 1-2/4-5 SHIFT SOLENOID | 5 - 1-2/4-5 COMMAND VALVE |
| 2 - 1-2/4-5 OVERLAP VALVE | 6 - DRIVING CLUTCH K1 |
| 3 - 1-2/4-5 SHIFT PRESSURE SHIFT VALVE | 7 - HOLDING CLUTCH B1 |
| 4 - 1-2/4-5 HOLDING PRESSURE SHIFT VALVE | 8 - SHIFT PRESSURE REGULATING VALVE |
After the gear change is complete, the 1-2/4-5 shift solenoid (1) is turned off. This reduces the pressure on the end face of the 1-2/4-5 command valve (5) to 0 psi and the spring pressure downshifts the valve to its initial position. The line pressure (p-A) is switched to the holding clutch B1 (7) and the end face of the holding valve by the downshifted command valve. The upshifted holding valve also allows the remaining pressure in clutch K1 (6) to be vented. See Fig 1.
