A tuned damper for a torque converter includes a piston plate with a pivot ring, an inertia ring at least partially rotatable in a circumferential direction relative to the piston plate, and a resilient element fixed to the inertia ring and frictionally engaged with the piston plate pivot ring....

This re- sults in an increased engagement stability and reduces the risk of clutch shudder. As a result of the lockup clutch proximity to the torus, the clutch interface is stiffer than in a typical torque converter. The Figure 23 Modular damper and torus designs with the iTC layout Torque...
Lockup shudder is another complaint that may be encountered. This refers to a vibration that is felt just before or after lockup occurs. This kind of problem can be hard to diagnose because the cause may be the torque converter, transmission or engine. Bad motor mounts, engine misfire, a ...
Shudder on take off Shudder when coming to a stop Causes Potential causes may include: Low or dirty transmission fluid Wire/circuit issue shorted to power or ground Failed torque converter clutch (TCC) solenoid Failed TCC assembly in the torque converter ...
6 Signs of Torque Converter Problems It isn’t easy to isolate and diagnose a torque converter issue without taking the transmission/drivetrain apart, but there are several symptoms to look for. A few of the signs of a malfunctioning torque converter include: shuddering, contaminated fluid, gears...
Shuddering When you feel a shuddering effect at the speed of 30 -45 MPH, then it might be because of torque converter issues. This creates the feeling of driving on a rough road or vehicle bounces where you notice it in a clear way if the issue arises. One might suddenly feel a shud...
In an example embodiment, an inertia of the inertia ring and a torsional spring rate of the resilient element are selected so that a natural frequency of the inertia ring is less than a shudder frequency.Jeffrey HemphillMichael G. Swank
Two types of shudder exist in continuous slip clutches: "initial shudder" and "long-term shudder". These shudder phenomena were investigated. The results indicated that the following factors influence the initial shudder: adsorption capability, elasticity, and "damping" properties of the friction ...
