5-7 Reverse Clutch Releases

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

Manual Valve

The manual valve is moved to the Neutral position and blocks line pressure from entering the reverse and drive fluid circuits. The reverse fluid from the clutch select valve is opened to an exhaust passage at the manual valve.

Clutch Select Control Solenoid

The clutch select control solenoid is signaled off allowing CLUTCH SELECT SOLENOID fluid to exhaust from the tcc regulator apply valve and the clutch select valve.

Clutch Select Valve

The clutch selector valve spring pressure shifts the valve to allow CLUTCH SELECT VALVE SIGNAL fluid to seat the #12 ball check valve allowing CLUTCH SELECT VALVE SIGNAL fluid to be exhausted thru orifice #41 into the CLUTCH SELECT SOLENOID fluid circuit which is routed thru orifice #68 and exhausted thru the EXHAUST fluid circuit.

TCC Regulator Apply Valve

The tcc regulator apply valve spring pressure shifts the valve to allow CLUTCH SELECT SOLENOID fluid to be exhausted thru orifice #68 and exhausted thru the EXHAUST fluid circuit.

#9 Ball Check Valve

REV/57R FEED fluid releases and unseats the #9 ball check valve against the DRIVE 2 fluid circuit allowing REV/57R FEED to exhaust into the EX BACKFILL fluid circuit.

5-7 Reverse Solenoid

The 5-7 reverse solenoid de-energizes releasing pressure against the 5-7 reverse regulator valve spring force. This blocks 57R CLUTCH FEED fluid from entering the 57R CLUTCH REGULATOR fluid circuit. 57R CLUTCH REGULATOR fluid is exhausted thru orifice #25 and #24 into the EX BACKFILL fluid circuit and thru orifice #21 into the EXHAUST fluid circuit.

5-7 Reverse Clutch Assembly

The 5-7 reverse clutch is released allowing 57R CLUTCH fluid to exhaust thru orifice #45 and #44 to the 5-7 clutch boost valve into the 57R CLUTCH REGULATOR fluid circuit. 57R CLUTCH REGULATOR fluid continues thru orifice #22 into the EXHAUST fluid circuit.
