Fig. 576: Torque Converter Clutch (TCC)

The TCC was installed to improve the efficiency of the torque converter that is lost to the slippage of the fluid
coupling. Although the fluid coupling provides smooth, shock-free power transfer, it is natural for all fluid
couplings to slip. If the impeller (3) and turbine (5) were mechanically locked together, a zero slippage
condition could be obtained. A hydraulic piston (6) was added to the turbine (5), and a friction material (7) was
added to the inside of the front cover (1) to provide this mechanical lock-up.
