What is the purpose of the torque clutch?
Your vehicle’s torque converter is the same as the clutch of a vehicle with a manual transmission. However, unlike a manual transmission vehicle, it uses fluid to transmit power to the transmission preventing your engine from stalling and allowing the transmission to change.
What is a torque convertor clutch?
The (TCC) torque converter clutch creates a one-to-one connection between the engine and the transmission that increases fuel mileage and reduces transmission fluid temperatures. When the clutch is disengaged, the torque converter allows the engine to rotate without stalling. …
What is a clutch torque?
The torque capacity of the clutch is the amount of torque that can be transmitted by the clutch when it’s slipping or when it’s fully closed. The torque capacity of a clutch depends on a series of factors: normal force acting on the clutch. number of friction elements.
How does a torque clutch work?
The torque converter casing connects to the flywheel, spinning at the same rate as the crankshaft, within the housing of the turbine. The impeller or centrifugal pump effectively flings the transmission fluid into the fins of the turbine that in turn spins or transmits the torque into the transmission.
What is a clutch pack?
Some cars use a multiple-disc clutch operation. In this setup, a series of friction discs are placed between steel plates. This whole assembly is known as a clutch pack. When fluid pressure is applied to the clutch pack, the piston engages, locking the assembly together and driving the wheels.
Why do torque converters fail?
Many torque converter failures can be caused by excessive friction, which means the torque converter’s needle bearings are damaged. Also, a faulty seals or faulty clutch solenoid can be to blame. A faulty seal can allow fluid to leak and become contaminated. A bad torque converter can damage a transmission.
What are the bolt torques on a Cat C13?

What’s the torque rating on a world American clutch?
World American 15.5” clutch assemblies are available with 7, 8, 9 and 10-spring disc designs with torque ratings from 1250-2050 lb∙ft. World American 14” clutch assemblies for medium-duty applications are available with torque ratings from 620 – 1400 lb∙ft.
What are the symptoms of a bad torque converter clutch?
The clutch gets disengaged to downshift. As its name implies, the sensor monitors the temperature of the transmission fluid. The symptoms of a bad torque converter clutch include engine stalling, poor gas mileage, and slippage.
How does the torque converter clutch ( TCC ) work?
The torque converter clutch (TCC) solenoid receives a pulsed voltage signal from the transmission control module (TCM). This signal causes the solenoid to move the valve that in turn moves the transmission fluid –which is pressurized- to the circuit of the clutch. When the vehicle is coming to a stop, applying the clutch is not a good thing.
