3-2 Timing/Coast Clutch (3-2 T/CCS)

DESCRIPTION
The 3-2 timing/coast clutch (3-2 T/CCS) is a variable force style (VFS) solenoid. The VFS type solenoid is an electro-hydraulic actuator combining a solenoid and a regulating valve. It supplies pressure to the S3 circuit to control the release of the direct clutch and apply of the intermediate and overdrive band during a 3-2 downshift. This solenoid also regulates the pressure in the S3 circuit to control the application and release of the coast clutch.

SYMPTOMS
- Failed ON- no engine braking (except in fourth gear), delayed 3-2 downshifts.
- Failed OFF- engine braking in 2nd/3rd gears, firm or flared 3-2 downshifts harsh 4-3 downshifts and harsh drive engagements.
