Ok, I advice you to learn the difference between advise and advice. And you threw in an extra comma and forgot the word "to", but that's more of an issue for Strunk and White.
Moving beyond your grammatical errors, you're right about the transmissions being the same. I've done a ton of research about these transmissions (Well beyond reading and quoting a few internet articles) as well as having repaired the one in my car already (twice, actually, after my first repair ended up with garbage aftermarket clutches). To summarize: As of 2010 all the gears, carriers, and clutches in both transmissions (from the front pump to the rear bearing) are the same. Different valve bodies, different interfaces to the motor, but the actual hardware is the same. And for those of you keeping score, all the repair and service part numbers for the 722.9s have been swapped out for the newer parts. ie, if you kill the transmission in your 2008 or 2009 and it gets warrantied through MB (or serviced through an authorized repair center) you'll be getting the new parts.

PPS - Internet tough guys will get verbally harassed as I see fit. See my signature.

True, the 2010 had the clutch upgrades ( I think there was an article on this that someone posted) and it never got public or given enough PR rap.

E63 P30, CL500 Sport
Taken from Automobile magazine:
The CL63 has AMG's seven-speed Speedshift transmission, which uses a wet clutch in place of a torque converter. Seen previously in the SL63 and the E63, the gearbox here has a different clutch pack and new software and is better mannered. Not only does it snap off superquick gearchanges and match revs on downshifts, but it now also equals the smoothness of a torque-converter automatic when taking off from a stop.

Mercedes did a similar move with the 5-speed tranny.... they added more clutch packs in the AMG version and I believe they even added more clutch packs in the V12 65 AMGs version.
