While accelerating my a/t acted like it was put into neutral, no gears work now

What is your question?

while accelerating transmission acted as if it was thrown in neutral (no noises or jerking) RPM's just revved. now no engaugement in any gear. linkage is fine, changed the filter, no metal in pan, fluid level was good, red and no burnt smell. pressure seems to be good fluid level canges on dipstick when engine running and upon removing plug on side of tranny with engine on fluid poured out hole like a water hose at full power.
