Why won't my lock-up torque converter lock up?

First, this car is fairly new to me and also most of the parts are fairly new also, i.e., 3 years old or newer.
Most of the work on this car was done by Anderson Performance East (APE) in Maryland.

According to Billy Anderson at APE the torque converter is a 9/11 Billet lock-up unit.  He remembers the car and the converter. 

The car has a 145mph speedometer.

Again according to Billy, because of the 145mph speedometer it will not lock up at normal lock-up speeds and so will need a manual lock-up switch.

First I tried the old paper-clip lock up, connecting A and F in the ALDL port.  This is what I remembered from the my old days with my TR.  No lock-up.

I put a simple continuity switch doing the same thing and drove around, trying to lock the converter.  No dice. 

Am I remembering this wrong? 

Is it worth getting the Monster Lock-up kit for $99?

The monster lock-up kit isn't going to do anything for you. You need to verify you have power to the lockup solenoid.

Also make sure the brake switch is working correctly!

Your Vortex article is just what I'm looking for.  Thanks.
