?? I have a 1994 chevy s-10 and we just replaced the filter and transmission fluid it will shift 2 times and no more what can it be?? I am so fed up with it please help me

It could be many things but I sort of suspect a clogged orifice or passageway in the valve body or a bad pump. Either one of these really needs a qualified technician to diagnose and repair.

I'm wondering if any body can help.I have a 97 venture mini van,it shifts only once,I changed fliud and filter,any ideas please help thank you
