I need some help understanding just what the Torque Converter (TC) does. I see references to the TC locking up in certain gears and not locking in other gears.<br><br>This is probably a dumb question but am attempting to learn because I have no idea what it does. Just what happens when the TC locks up. What does it do for me?

 

Here's a start:<br><br>http://auto.howstuffworks.com/torque-converter.htm<br><br> ;D

 

Thanks for pointing me to that. Maybe it will help me understand just what is going on.<br>
