I ordered me one of those FLT 65e's with the vac mod kit, that thing is pretty cool. Its a manual line pressure adjustment mod that works with the throttle. For example when driving around town easy on the throttle it will shift nice and easy but when you get on it you can have nice firm shifts, Plus if you ever have any electrical problems your line pressure will not be affected which can prevent tranny damage!

mine was like 3000 with shipping included! but that beats rebuilding 6 times!
