2007 Dodge Nitro R/T CONVERTER-TORQUE DESCRIPTION

CAUTION: The torque converter must be replaced if a transmission failure resulted in large amounts of metal or fiber contamination in the fluid. The torque converter is a hydraulic device that couples the engine crankshaft to the transmission. The torque converter consists of an outer shell with an internal turbine (1), a stator (3), an overrunning clutch, an impeller (2), and an electronically applied converter clutch. The converter clutch provides reduced engine speed and greater fuel economy when engaged. Clutch engagement also provides reduced transmission fluid temperatures.


The converter clutch engages in third through fifth gears. The torque converter hub drives the transmission oil (fluid) pump. See Fig. 267. A turbine damper (6) has been added for some applications to help improve vehicle noise, vibration, and harshness (NVH) characteristics. The torque converter is a sealed, welded unit that is not repairable and is serviced as an assembly. download
