If the trans fluid was old or extemely dirty, and you had it serviced (assuming filter and some fliud changed) the new fluid which has strong cleaning detergents might have lifted dirt and varnish throughout the tranny and maybe clogging up the internal parts, if this is the case, I would have the entire tranny flushed out and all new fluid put in.
