my 04 mcS 6 speed broke and it needs replacing.
i was thinking about getting the 05 6 speed.
is it a perfect fit?

 

Yes it will fit.....but I believe if you have cruise control you will lose it. On the up side.....you will gain quickness, as the 05 has better gearing than the 04. And how do I know this? Just so happens im changing out my 03 MCS tranny for a 05 MCS tranny, just for the gearing tomorrow. Along with adding a LSD and a new clutch and flywheel
