During the initial period (the first year after your braces come off) you will wear it 24/7 for several months. Later, your orthodontist will tell you that it's OK to wear it only at night -- every night. After another year goes by, you can wear it several nights per week.
As mentioned, converter shudder is usually temperature related. As transmission fluid recycles back through the engine turbine, it picks up frictional heat. Once the amount of heat generated by this friction surpasses the transmissions cooler's ability to shed it, the fluid thins and power transfer becomes inconsistent.ransmissions can shudder in a very similar manner to torque converters. To determine whether the shudder is tranny or TC related, run your vehicle for a little while till it begin to shudder and immediately park it. With your foot on the brake, put the transmission in Drive, and apply light throttle.
Drivers usually notice transmission shudder when they are driving between 40-60 mph. They feel the vehicle begin to shake, as if they just drove over a rough patch of road. The sensation lasts for 3-4 seconds, then everything returns to normal â for the time being.
