The torque converter has a clutch inside of it. It resembles a manual clutch but less surface area and made to work in fluid. It is controlled by fluid pressure that comes from the transmission. The transmission is controlled by a solenoid that is controlled by the computer. So you can program/tune the clutch to come on when you want. The factory typically has it come on in 3rd and 4th. I would not get a converter with out this clutch, what would be called a non lock up unless you are building a track only car. With out the clutch you will loose fuel economy - MPGs.

I have driven in 3rd with no lock up on the freeway and it feels crazy. My first car had a lockup converter and thats all I have ever driven. Unlocked at 70 mph in 3rd its about 4K rpms. Let off the gas and the converter floats to idle. Start giving it gas and it free-revs like its in neutral till it reaches 4K then it starts to pull.... That **** is a trip for us younger guys.
