Just recently pulled transmission to do rear-main seal and replaced trans filter and fluid and installed it all back. If i put it in reverse and accelerate harder than normal i get a noise like something is slapping. Going forward i have no noises or slapping whatsoever no matter how hard i accelerate. Any suggestions?

It only does it when you really put a hard load on it in reverse. Could this be the flex disc spreading apart in reverse and binding up??
