The funny thing about transmission shudder (torque converter shudder) is the quick nature of the whole thing. This occurs because the transmission fluid is contaminated and the contaminates, being suspended in the fluid, prohibit good pressure contact between the transmission plates when they are applied. Shudders occur most often when shifting into overdrive or when in overdrive and going up a slight incline. As mentioned, converter shudder is usually temperature related. Basic transmission can be combined with multiple power take-up elements including the torque converter, the hybrid drive, and the integrated power take-up. Torque converter shudder fells like a slight to heavy vibration in the transmission, and is usually accompanied by an interruption in power transfer. Each cylinder has one of each and you are lucky if only one cylinder is misfiring. What feels like a transmission shudder is actually caused by faulty fuel injectors and ignition coils. I took the vehicle back on 12/7 /18 with the same complaintsThey had to replace the torque converterI picked it up on 12/22/17, issue with the transmission was still not resolvedOwners with the same issues are being told gm knows but can't fix transmission issue. › 2016 honda odyssey transmission shutterįrequently Asked Questions What causes transmission shuddering?.
› 2008 ford expedition transmission shutter A concentrated friction modifier formulated specifically for INSTANTLY eliminating torque converter lock-up shudder.Moreover, experiments using a dynamic absorber are conducted using an actual vehicle, and the suppressive effect of the dynamic absorber on the shudder is confirmed through experiments. Numerical analysis reveals that (1) applying dampening to the dampers is the most effective method by which to suppress the shudder and (2) the shudder can be completely suppressed by attaching a dynamic absorber. The most effective position at which to add the viscous damping and the countermeasure to suppress the shudder by attaching a dynamic absorber are analyzed. A countermeasure for suppressing shudder is also proposed. The entire system from the piston to the tires, including planetary gears, is modeled as a linear multi-degree-of-freedom system using a Lagrange equation of motion, and the shudder mechanism is clarified. The characteristics of friction in the lock-up clutch is found to have a negative slope with respect to the relative slip velocity. In the present study, experiments are conducted to analyze the shudder mechanism using a bench test apparatus and an actual vehicle. In the process of locking up, the torque converter turbine locks to the clutch and rear housing. The issue is it shifts in and out of overdrive repeatedly if I climb a hill or put load on it. Tranny was serviced (flushed) at 30K and at 80K. Lock up shudder occurs during the lock-up phase when the torque converter provides 1:1 power to the transmission. I have a 2003 Z71 Silverado with a 4L60e (M30) transmission. Therefore, the shudder adversely affects passenger comfort. friction modifier designed to instantly eliminate torque converter lock-up shudder. When shudder occurs, the power train, as well as the tires and the car seats, vibrates. In the process of slipping at the lock-up clutch, frictional vibration referred to as shudder sometimes occurs. When the rotating speed of the turbine approaches that of the pump, the input shaft is directly connected to the gear train through friction by means of the lock-up clutch. This occurs after the vehicle is rolling and ceases when it comes to a stop. When the internal clutch applies, they call this torque converter lock-up. This transfers more of the available power and helps fuel mileage. In order to overcome this disadvantage, a lock-up clutch system in the torque converter has been applied. This clutch 'locks-up' so the transmission torque converter rotates the same speed as the engine.

Compared to manual transmissions, automatic transmissions suffer from poor fuel economy. In recent years, automatic transmissions have become widely used in cars.
