i.e. your valve cover leak could be dripping down and blowing back onto the tranny making it look like RMS leak... i wouldn't pay for a tranny drop just to replace RMS - other things could be done at the same time with it out (gut precats, replace O2's, det sensor, EGR, etc) - may want to wait until you know more about the car and what it needs... valve cover and RMS leaks are a problem on a majority of our cars due to age and mileage
