How does the torque converter lock up the clutch?
The pressure required to accomplish converter lock-up derives from the transmission’s integral pressure pump that is driven by the engine via the torque converter. Based on inputs from the PCM, some of the pressure is directed through either solenoids or valve shuttles in the valve body to activate the actual torque converter lock-up mechanism.
Where do I find the torque converter part number?
Chrysler, Ford, General Motors etc (alphabetically), then by Transmission Type (again alphabetically) and finally by Converter Code (TCS Code). The section below the Converter Part Number (Grey Band) is for information unique to the converter that may assist you in the correct idenification.
How does the lock up function of a converter work?
The lock-up function is accomplished by solenoids that control the flow rate, and hence the usable pressure of pressurized transmission fluid to vary the amount of converter lock-up.
Is there a problem with the torque converter?
It could be a problem with the transmission, or the transmission could be perfectly fine and it could be a problem with the torque converter. Torque converter issues on a lot of older transmissions can be diagnosed by carrying out a stall-speed test.
What is torque convertor lock up?
Lock-up torque converters contain a torque converter clutch. When the clutch engages, it allows the converter to “lock” the engine to the transmission input shaft, providing a direct 1:1 engagement between the engine and transmission.
What is a torque converter solenoid?
The torque converter clutch solenoid is a common part that fails within the automatic transmission . The solenoid valve controls the fluid pressure of the hydraulic transmission, which enters the lock-up clutch. This can cause various symptoms, such as slipping, overheating, and rough acceleration.
What does a torque converter do?
A torque converter is a type of fluid coupling, which allows the engine to spin somewhat independently of the transmission .
