Tight ps gearbox??

If you try to adjust it, it may void warranty. Just exchange it.
In my opinion they should work perfect out of the box, no break-in necessary.
These are a pain in the butt to swap so I was hopeful that its just a pressure adjustment and it be fine . The warranty don't mean crap. The parts store has to exchange it. What really sucks is the old one worked well but it just leaked a lot . I also just put the a new one in the duster thats the old style and it worked perfectly.
