Shop Torque Converters for your 1998.5-2002 Dodge 5.9L Diesel. For performance and competition applications upgraded torque converters are available. The use of forged billet steel for items such as the front housing provide improved support for the internal lockup clutch, allowing it to remain completely flat under all condition. This results in improved lockup performance and less slippage. These performance converters can also include a long list of upgraded internals such as a stronger turbine and impellers, additional friction surfaces/area, improved clutch materials, Torrington roller bearing construction, tig welded pump and turbine fins, as well as Billet stator cap and apply pistons. Symptoms of a bad torque converter can include slipping, overheating, contaminated transmission fluid, increased stall speed, shuddering during acceleration, and unusual sounds. Some items that often fail include the torque converter clutch or clutch solenoid, as well as needle bearings and seals that can become worn. A torque converter is a fluid coupling device that transfers the engine's power to the transmission. It is located between the engine and the transmission. One side of the converter slides on to the transmission's input shaft and the other side bolts to a flex plate at the back of the engine. The primary components that make up the converter assembly include the impeller, stator, turbine, clutch, and front cover. When the vehicle is running, the impeller is driven by the engine and acts as a centrifugal pump. The impeller forces fluid outward toward the turbine, which is connected to the transmission's input shaft, causing the turbine to spin.
