I don't see any replies yet, so here's mine.
you check the ATF level with the engine running, trans in Park, van sitting
fairly level, and warmed up is better.
It's very important not to overfill any automatic transmission !
also........there is a separate section for the ring and pinion gear oil.
Takes a 17 mm allen to remove the filler/level plug.
I'd be concerned about this trans.
It can be somewhat normal to have minor slipping, for 30 seconds or so on a
very cold trans, or one that has sat a week or so.
But what you have .........
I'd drop the pan and see what's in there.
if it's not full of junk, or sludge, or metal particles or obviously wasted
there, I'd clean or replace the screen,
try new ATF,. and perhaps a can of Trans-X, and see what happens when you
run it next.
be sure the ball pivot at the rear end of the throttle cable on the lever on
the side of the trans is smooth turning ............as in not jammed or
rusted.
It's a bit hard to get to or see very well, but those can rust and not
pivot, possibly causing shifting up problems.
