Third Clutch Applies

WARNING: This page is about a different variant/trim than selected.

2-3 Shift Solenoid (SS) Valve

The PCM energizes (turns ON) the 2-3 SS valve. The PCM blocks the exhaust of the 2-3 SS valve fluid to create high pressure in the 2-3 SS valve passage. High fluid pressure from the 2-3 SS valve moves the 2-3 shift valve into the upshifted position.

2-3 Shift Valve

High fluid pressure from the 2-3 SS valve holds the 2-3 shift valve in the upshifted position. The 2-3 shift valve allows drive fluid to pass between two valve lands and enter the third clutch circuit. Third clutch fluid is then routed to the third clutch piston, and the fluid applies the clutch. In addition, third clutch fluid is routed to the following components:

Checkball #11
2-3 Accumulator Piston
Third Clutch Exhaust Valve
Torque Converter Clutch (TCC) Solenoid Valve
3-4 Shift Valve

#11 Checkball (Third Clutch, Orificed Third Clutch)

The #11 checkball is located in the case cover. Third clutch pressure seats the checkball, which routes fluid through orifice #31, where the fluid enters the orificed third clutch circuit. Orificed third clutch fluid is also routed to the 2-3 accumulator valve, to the 1-2 & 3-4 accumulator valve, and to the TCC solenoid valve.
