Check your Extention housing bolts.
My 4r70w had play in the output shaft when I changed the rear seal. It turned out the extention housing was half a turn loose on all the bolts.
Yours could be bearings also tho. but tightening some bolts is easy to check.
Dont over tighten them tho just check em to see if they are loose.
