What is the torque converter clutch solenoid circuit?
The solenoid moves a valve that sends pressurized fluid to the clutch circuit, engaging the TCC. When the clutch is disengaged, the torque converter allows the engine to rotate without stalling. While the vehicle is slowing and approaching a stop, the TCC’s application is undesirable.
Is the torque converter clutch solenoid inside the transmission?
The torque converter is located between the rear of the engine and the front of the transmission. The clutch creates a mechanical connection between engine and transmission. That means the solenoid is designed as a “variable force” solenoid that provides varying amounts of pressure to the converter clutch as commanded.
When does a torque converter clutch wire fault?
TIP: Remember in most cases there’s an internal transmission harness that connects the TCC solenoid and shift solenoids, so the wire fault may only happen when the transmission is hot or cold. Or, when the vehicle is driven above bumps or when making a turn. Make every attempt to recreate it!
How is the torque converter clutch controlled by a solenoid?
The converter clucth does not lockup at these low speeds therefore heat is generated. This clutch is controlled by an electrical solenoid. The torque convertor clutch is locked changing the fluid coupling to a mechanical one.
Where are the solenoid plungers on a transmission?
Your transmission shift solenoids mount on the transmission valve body that controls fluid flow through the various circuits and passages in the transmission. The solenoid plungers are constantly bathed in fluid from the transmission, and metal salt from the manufacturing process and normal wear,…
What are the transmission codes for Jetta 2005?
Hi, I have jetta 2005 2.0l 98k and transmission code fdf. Transmission is in leap or fail-safe mode and there are 6 codes po753, po758, po763, po773, po743, po785. I’m not able clear codes with my generic obd2.
