Hello,

Ok, did they do a fluid and filter change?

What did the tranny fluid look like? was it normal color or was it a pink foamy color?

Is Engine Light On? If so need to have codes read. Your local parts store will usually do it free.

You say that it is bucking, if this is so then it may not be tranny related.

Sorry for delay, do he get a list of the codes? if so post them...

Not sure about the sushing sound, but could be a vacuum problem under the dash.
