Question about a Bonneville Tune--Not Your Normal Tune

Hey guys, I'm having an issue with part of my tune, So that's why I'm asking here. I've been around Bonnevilles for a long time, and I currently have a 96 SSEi (L67 S2 with a 4T60-HD) and am using a 97 PCM to control everything because of the tunability of the 97 PCM vs a 96. The only thing that I (and my friend Don) can't wrap our heads around is the TCC lock. I've tried changing settings in a bunch of ways, and nothing works. It runs and drives perfectly besides no TCC lock, I was wondering if any of you knew a trick to this at all? I have attached my HPT tune file. The only odd thing we noticed is that under the speedo section, in the Gear/Tire Calc, the selection for FWD or Transaxle is selected as No and will revert back to that if I click on Yes and hit commit.

TIA!

Are you referring to the TCC apply/release speed ??? and that's odd about the transaxle/fwd thing.:confused:
Very late reply but I thought I'll give it a try.
