Lockup

What exactly locks up the converter? Does the line pressure variate or what's the story? I'm a noob, I have a TH400 in the 67, and a T56 in the TA, so I have to ask. Just wondering. Thanks fellas.

There is an actual clutch inside the torque converter that "grabs" or locks, stopping the slipping that the unit normally does.

But it's controlled electronically? Does it variate line pressure or something? I'm dying to find out... LOL

A solenoid causes a valve to move applying a clutch not so different in principle than the clutch in your standard and makes the coupling direct straight through just like the clutch in your car
