TRANNY QUESTIONS
Alright first and foremost lets get this cleared up...All of you BMW and Audi owners that may lurk among the AMG forums who got all excited when you read the title were NOT talking LADY-BOYS so you can go about your lurking.
A few questions here and maybe a few difficult ones?
First; The CLK63 rev matches down shifts--but--to what extent?
ex: Highway cruising, center lane, 3 lane road. Your about to get sandwitched between cars and there is a semi truck ahead, your time is running out quickly and thus you need to "gap" the car on your left or right, with the one infront of you. Your in 6th gear for sake of the example, and needing/wanting the greatest amount of torque to launch between cars u want to drop to third. In my shelby its as simple as firing it up from about 2000 rpm to about 4/5-5rpm and switching gears. can you just drop two on the amg? is the car expecting you to make up the difference in your throttle manipulation? Are you going to smack an "rpm wall" and get sucked foward in your seat? anything please.....
Second; How much abuse can these tranmissions/clutches take? Im well aware that mercedes/amg designed the car from the ground up to be a street track performer, but behind close door testing leaves me wondering if i could really bang gears in a 30minute sport cup race.... what do you all think?
Lastly: DTM guys, or and merc guru...how about a true MANUAL Sequential for the 63? Can one be adapted, surely its not unheard of because we know the DTM race car had one...
Sorry lot of junk but i have not seen better advice/knowledge shared anywhere else on the internet as well as it is here

In the CLK Black, if you're in 'S' or 'C' , and you nail the gas, the car will downshift 2 gears.
If you're in 'M' , you need to go down 2 gears and there's no rev matching.
Search this forum for track experiences, plenty of guys do it.

CLK 63 AMG Black
The CLK BS does not rev match. For acceleration in traffic, that is irrelevant, as just mashing the throttle will move the car into all the acceleration one can use in traffic.
The rev matching is desired only for downshifting while braking. Our cars don't do that, but heavy brake application settles the rear, so it isn't an issue on track.
Not sure why you need to know, but those are the facts. AS

I am a little confused. You list the C63 as the car you drive yet you don't know if you can co-exist with a mostly automatic transmission. And wouldn't your experience with the C63 transmission answer your first question?

manual is true manual though, as far as throttle imput goes. Floor it in 5th gear going 50mph and it won't downshift. You can bounce it off the rev limiter all day and it wont upsift. Sure the down shifting is slow, but hopefully the new MHP tuning will prove to have long term reliability. Anyway, I always drive mine in manual. the auto modes are WAY slow and sluggish or my taste. Upshifts are very fast though, i really love the way the car grabs gears especially when short shifting under WOT - you really feel the rear dif especially if you upshift mid turn - the car likes to chirp the ties. All in all i give the gearbox an 8 ot of 10. if the mhp tuning is that good it'll make the car perfect and WAY fun to drive.
