      I'll check with the guy that built it this week . It's possible that   
   the rebuilt converter he supplied doesn't have lockup , I understand   
   that some don't but that may be an aftermarket thing

   A torque converter is like one fan blowing on another fan to transfer   
   rotation while allowing slippage without wear, though it wastes energy as   
   heat. The lockup is a clutch that connects the two fans (turbines) together   
   when conditions allow. The indication of lockup is the tach needle moving in   
   sync with the speedo needle instead of jumping when you change gas pedal   
   pressure.

   In Drive with the brakes locked full throttle engine RPM should be around   
   2000 unless you have the actual specs.   
      
   Torque converters developed the simpler fluid couplings of the late 1930's   
   and were highly improved for WW2 airplane engine superchargers, to isolate   
   crankshaft power stroke vibrations from the high flywheel inertia of the   
   compressor rotor.
