well if it has an auxiliary trans cooler, you could remove the output hose and drain a quart then replace a quart with it running. its a pita but works, its how you do some cars too by the book. on another note, my dad's 96 suburban had a troublesome trans the way you described. if it does bang into gear when hot, i would bring it to a trusted trans shop. i think its something with the planetary gears. also scan for tranny codes. could help!
