When I start the van and let it warm up there is like a screeching sound and then when I drive it it normally takes a long time to switch into first gear and to get going..could this be the serpentine belt?

Serp belt has nothing to do with trans shifting while screeching noise could come from it.
With noise, start with checking the belt tensioner arm - it should return without binding after being swung by hand (make sure the engine is not running when testing this!).
This is an extremely common gm (not only gm) problem - the tensioner arm gets corroded, and doesn't provide sufficient belt tightening.
Trans - sounds like you have leaking internal seal(s), and only overhaul or replacement will take care of that. But first check fluid level!

The screeching during start up could be a belt but I doubt it. Serpentine belts are good for a long time, plus have self adjusters. Look at the belt, if the ribs on the bottom are cracked and split, replace it. It is easy and any car guy friend should be able to do it. I'm more concerned you have a transmission problem. Have you checked the fluid? Let us know some details..

Screeching could be caused by the belt of one of the bearings it is driving on. Kind of sounds like your trans is slipping or low on fluid. Get some diagnosis done on it.

before overhauling transmition check fluid if bron and smells burnt change fluid and filter first this sometimes takes care of this cause filter gets plugged
