When I had HTS build my tranny I specifically asked for it to lock up in 2nd and he said he would tweak the VB and send instuctions on how to do the rest. I looked at his instuctions and went cross-eyed. It's got a bunch of L1's and L6's, whatever that is so I never messed with it. After reading this post I think I'll give him a call because I really want it now. Recon the instructions on the TST website would be the same for all transmissions?
