I just had the transmission fluid changed and oil changed and there is a wierd burning smell. Why?

I just had my 60K maintanance with an oil change and my transmission fluid changed and their was a wierd burnt smell after I got done driving my car. Why is this? Could the mechanic have used the wrong transmission fluid? Or, is it normal for new transmission fluid to smell?|||MIGHT HAVE SPILLED SOME ON THE EXHAUST! CK FOR ANY LEAKS AFTER DRIVING AWHILE.********* TAKE IT BACK AND HAVE THEM LOOK AT IT!!!|||When they changed the fluid they probably spilled fluid on the engine and exhayst manifolds. Check for leaks, if none wash engine off when cold with hot water mixed with a little dish detergent. and hose off.|||maybe the mechanic spilled some oil on the engine or exhaust pipes and it it just burning off if the smell persists have it checked|||Probably spilled tranny fluid on the exhaust
