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.
I have a 2003 F-150 with a 5. 4 engine. There is slack in the transmission around the torque converter. Whwnever you slow down the gently bump the accelerator you hear a bumping noise.he torque converter on my 2005 Ford F-150 has had two torque converters fail in the drive train. One failed within the 3 year or 36,000 mile warranty period. The second torque converter failed around 50,000 miles.
