transmission slip
Just bought a 2002 Expedition XLT 4.6 triton yesterday.
when i put it in drive it won't move anywhere, when i rev it to like 3k RPM a few
times it hooks and starts going, shifts fine to other gears too. also it whines/whistles both on idle and when
driving. the car only had 25k miles so i highly doubt that it could be a mechanical
issue. once it drives it will shift in gears fine but when i punched it it revved to
about 5k and didn't shift nor pull just slipped a lot.
any idea what it can be?

Absoutely low fluid can cause the problems you have. Like I said before, you better hope it is the fluid level or it becomes a trans rebuild. You may have done enough damage driving it around already to require a rebuild.

Big Greenie is right about the fluid. The transmission is nothing but a hydraulic pump. Fluid is diverted through valves and that is what gives your forward/reverse and the gears. No fluid=no forward/reverse motion. Low fluid also means that things burn up really fast. Heat is a transmissions worst enemy. At this point, if I was you, get it to a shop and don't drive it there. It maybe too late by now. For some reason I don't think it is fluid level. If it was, it wouldn't go into forward/reverse at all and be able to shift. It would slip through the gears and gear changes. Something else is going on. Have you checked your fluid level? Just an FYI, when I worked at a Ford dealer years ago, we would brand spanken new vehicles come in with 5 miles on them that needed new engines/transmissions. Nothing is immune whether it is new or not. Good luck!

just checked, the level is a bit above full and it looks like the oil was just changed, it's fresh. even if i need to rebuild it it's not a big deal, i was hoping that it will be something inexpensive
