would you call it more of a shuttering feeling, or can you feel it slipping? or will it slip if you nail it off the line or shake and shudder?
if this is the case^^^ id either break the pan free on a corner and dump out the extra fluid plus 1 more, or suck it out the dip stick. then drop a quart of lucas trans medix. warm it up, top it off with new fluid. then pray for the best.
its also possible the filter is clogged up if it was not changed when it was flushed. most places dont change it when they flush it. if thats the case you may want to drop the pan change the filter, get 7 quarts of new fluid and a 1 quart of the lucas stuff.
