Where is the tranny leak? If it is the rear output bearing, and oil is coming down from the right rear of the tranny or the boot in front of the final drive, then replacing the seal is fine.
If it is either the front or rear input shaft seal, then it can be a clutch replacement required, as either of these tranny seals leaking will contaminate the clutch with oil.
If they pull the transmission, be sure they replace all the tranny seals. If the rear input shaft seal leaks, it can cause the clutch slave cylinder to go out later, another clutch destroying event, so they should replace the slave cylinder any time the rear input shaft seal leaks.
This is a great bike, but it does have it's Achilles heels. The clutch slave cylinder being one of the most prominent.
You only have around 12K miles on it, so if the tranny has to be pulled I would not worry about the rear engine seal. If around 50K though, anytime the tranny is pulled I would replace ALL tranny seals, the clutch slave cylinder, and the rear engine seal and O-ring. Clutch replacements are a high labor job, so anytime you have a chance to do a preventive maintenance job on any of the things that can take the clutch out, do it.
Also, a great number of us have drilled a drain hole in the clutch slave cylinder mounting boss on the rear of the transmission to allow fluid from either a failed slave or rear tranny input shaft to drain out and not be forced into the clutch assembly.
