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.
The Torque Converter can go bad, and many people mistake an engine miss, torque converter shudder, or an engine vacuum leak for a converter going bad. An out of adjustment brake light switch can also cause the torque converter to no lock up sometimes.A sticking valve within the transmission is the usual cause of an erratic lock up that will mimic a bad converter. Rule out the obvious before you assume its going bad, and/or have it rebuilt.n out of adjustment brake light switch can also cause the torque converter to no lock up sometimes.

If you are working on a vehicle that is expected to have torque converter shudder, you must first determine if the shudder is trans or engine related.You may do this by brake torqueing the vehicle, trying to duplicate the same load the engine had when experiencing the shudder.f an engine miss is experienced at this time, the most likely cause would be plugs and or wires. Replace the plugs and wires and the shudder will probably go away. If no engine miss is experienced, the problem is most likely transmission or fluid related.
