Second Coast Clutch Applied

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

Manual Valve: The volume of line pressure entering the 32 fluid circuit at the manual valve is increased to accommodate the added torque requirements for engine braking or increased engine load.
2-3 Shift Solenoid (SS) Valve: The 2-3 SS valve is energized, allowing feed limit fluid to enter the 2-3 signal fluid circuit. 2-3 signal fluid overcomes 2-3 shift valve spring (372) force and moves the 2-3 shift valve (371) to the applied position. This allows 23 regulated fluid to enter the second coast clutch fluid circuit and also opens the overdrive clutch feed 1, intermediate clutch and 345 fluid circuits to exhaust.
3-4 Shift Control Valve: 2-3 signal fluid is also routed to the 3-4 shift control valve (346) and moves the valve against 1-2 signal fluid pressure to keep the 3-4 shift valve (345) in the applied position.
Second Coast Clutch: Second coast clutch fluid is directed to the second coast clutch piston to apply the second coast clutch plates.

NOTE: If the vehicle operating conditions are such that the TCM signals a Third, Fourth or Fifth gear state, the 2-3 solenoid will be de-energized. Thus a downshift will not occur until the vehicle speed is low enough not to overrev the engine - calibratable in the TCM.
