You probably have a bad torque converter,If is still acts this way the the tranny needs to be dropped and looked at by a pro.

Of course you could look and see if you tv rod is connected.It has a spring and connecting metal rod connects from the throttle to a arm on the tranny.Make sure they are hooked up.
