Sorry for the delay in responding. All fluid levels are fine. A little dirty but not bad and no visable metal flakes.
I can give more info on the problem. It seems to be RPM dependent. When its around 2000-2300 RPMs its doing almost a little tranmission surging when going slower, say 30-45 mph. You can tell its the tranny and its not a full slip but more of a surge.
When on the interstate, doing 65-75, when its at those RPMs and starts to go up a hill in OD, if it doesnt downshift it will make a sound that reminds you of a tire hitting a rumble strip. Not super loud, but its got some volume. I tried to record it with my phone but its hard to hear. When you give it gas and it downshifts, then it goes away. By not going in OD, it runs at a higher RPM so it doesnt do it, but when the RPM's hit that level it does the surging even when not in OD, so I don't think its a particular gear problem.
Also, I have begun to notice the smell of tranny fluid when I get out after driving it. There is no tranny fluid on the ground but its just a smell of it.
I am somewhat confident its in the tranny, but would like someone to give me their thoughts on it.
