Default powerglide moving slieghtly forward during rev up?

i have atci trans with a 9.5 inch 4500 convertor and it moves about 1/2 inch to two inched forward when i rev it in park. it also rotates tires about half a turn when it is lifted off ground so tires can spin . any thoughts would be greatful. thank you

Mine sometimes moves like that when I fire it up. Scared me the first time it did it.

If it is a glide I think it will be fine. My glide rocks as I rev it in park always has.
