To Formula413: The car I was writing about was my Accord LXi. That's interesting that you can measure torque converter efficiency on a gauge. The other way is to divide the car's speed by the speed you would have if there were no slip. In my case, I know that my car goes 24 MPH for each 1000 RPM in high gear if there is no slip. I would multiply the engine RPM by 0.024 to calculate the speed of the car without slippage.

32 MPH/(2000 RPM * 0.024 MPH/RPM)
=32/48
=0.666
=66.6% torque converter efficiency

Modifying a torque converter would not be an easy thing to do. They are welded shut, so to modify one you would have to cut it apart, do your modifications to the internal parts and then weld it back together. Then you would have to balance it to make sure you don't get vibrations. I don't think you can get a rebuilding kit for a torque converter.
