Are you sure it's not residual oil from the filter change...dripping down the frame? Otherwise there could also be "blow-by" running down the motor & onto floor. Either way - have the dealer take a looksee.

 

My guess is the trans plug was not installed correctly. Mine did the same thing. (bought used from a dealer). My bet is the tech cross-threaded the plug and it wouldn't seal.

 

Thanks for all of the help guys..I have called my dealership and told them that I was bringing it back in on Monday morning. I hope that they didn't strip the trans plug threads. Seems as if that would be a pain for them to fix and might try to keep my scoot for longer than the day. I'll let you guys know what happens.
