Well. my 04 S transmission went yesterday after 40K miles.
i was wondering if i could replace the transmission with an 05 or 06 because there gearing is better then the 04.
and another thing, when i replace my transmission would it be really easy to replace the clutch while i'm at it?

 

Yes, you can swap in an '05/06. IIRC cruise will only work in 3rd gear.
Also yes, you might as well throw in a new clutch as long as the tranny is being replaced.
