904 No Reverse

Ok, so I just went out to move the Dart for street sweeping. After a couple cranks from sitting for the last week it fired up but didn't seem to rev up like usual, not a big deal I was thinking. Then I go to put it in gear but I didn't feel it engaging through the gear changes? I let it run for about 5 min. or so (mind you it still doesn't seem to rev up) then I go to pull it into the driveway but it won't go into reverse? WTF! I check the fluid and it is full and doesn't smell funky. I ran it again through the gears and went under it to look at the lines for any kinks but it still doesn't feel like it even tries to go into reverse. This thing only has like 5k on it. any ideas?

also on a side note while I was under it I noticed the trans. was pretty hot to the touch. is that normal considering only a 5 min. or so idle time with no actual driving involved?
