Magnum V6-2.7L VIN T (2007)
The TCC (9) 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 and turbine were mechanically locked together, a
zero slippage condition could be obtained. A hydraulic piston with friction material was added to the turbine assembly to provide this mechanical
lock-up.
In order to reduce heat build-up in the transmission and buffer the powertrain against torsional vibrations, the TCM can duty cycle the torque converter
lock-up solenoid to achieve a smooth application of the torque converter clutch. This function, referred to as Electronically Modulated Converter Clutch
(EMCC) can occur at various times depending on the following variables:
-
Shift lever position
-
Current gear range
-
Transmission fluid temperature
-
Engine coolant temperature
-
Input speed
-
Throttle angle
-
Engine speed
