Do you have the speedo calibration screens set up properly? TCC lockup is highly dependent on vehicle speed.

There's a program an Hptuners guru wrote called BC_trans, that makes it really easy to setup trans shift points and tcc lockup points for modified vehicles. It should be easy to find with a google search.
