    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.

   Ummmm Jim ...
   I found out today that basically all OE TC's that fit 700R4 trannies are capable of lockup . I also learned that the tick coming from mine is most likely to be internal since there are no loose or too long bolts in there . And with the flywheel cover off it is a lot LOUDER . As I said I'll be talking to the shop that built the trans later this week . I know for sure it ain't lockin' up because the tach needle tracks with throttle instead of with speedo .
   I was going to do it today , but we were out of buns - the grandson is up for a visit and wants brats-n-tots for dinner - and I'm the baker . The last batch - hot dog buns - has about 13 minutes left on the timer ...
