there was only really two problems with the lly if you leave the intake stock it can over heat if you tow alot and i mean like over weight thats due to the turbo mouth piece its restriceted there two fixs to this problem a good intake or replace the stock LLY mouth piece with a LBZ or LMM mouth piece. The earlly LLYs had a little injecter problems but it wasnt a huge deal and if they go on the truck i buy it should be under warenty. The only thing the truck needs is the Dmax badge he took the old Dmax diesel one off and he wanted to debage the whole thing, but then he saw the new dmax allison badge but never got to put it on so its a little embaresing not showing the diesel pride but heres a few pics of it.
