Do you mean engine/drivetrain heat coming out of the air vents? I haven't had anything like that. However, the tranny tunnel does get warmer in my 2005 than it did in my 2000, both 5-speeds. No heat "trouble" to speak of, though.
If you mean having hot air coming out of the defroster vents when you have it set for floor heat, yes mine does that too. When I took it to the dealer for other work I was told this was normal. Not sure why but I guess it does not hurt anything.
