If you have a locking diff, you will have a button on the dash to lock the diff. No Titan has a LSD from the factory. I know that there are in fact line pressure adjustments that are computer controlled because Uprev has software to do that. I dunno exactly how that works, I think the TCU is inside the tranny. Level 10 and IPT will ship rebuilt trannys, you might call them and ask how the pressure settings work. There are various posts on the net b-i-t-c-hing about both Level 10 and IPT, so caveat emptor.
