Just did the same to my 5.5L swapped SLK. You can leave the shifter control module (little module inside shifter) inside the console and just leave it in N.

or do what I did and make a mechanical throttle linkage and weld it onto your throttle body. that option will also disable your ASR without the triangle lighting up all of the time! win win!

oh, where did you get the single-mass flywheel?

As stated by others clutch is the weak link. It starts slipping in 4th and beyond. (sometimes 3rd when cold) I have a spec stage III clutch going in when it warms up a little. at the same time, I'll be installing a 2.82 diff out of a CLK55 because right now the ratios are just too short and I only want to shift once from 0-60. I also want cruise RPM's to be around 2500 @ 80mph.

That'll grip and chatter and do all the good things a clutch is supposed to! eager to see if the transmission takes it!

no one has broken one yet even though people thank that the NSG370 isn't very strong.

Hi guys

All back together drives good all the mechanicals are working fine

But I have a problem with the ECU not receiving a speed single from the auto gear box so it some times hangs onto the revs

But when I leave the selector switch plunged in (see pic) and in park the Rev limiter cuts it at 4000rpm like is should but when I drive it revs all the way all normal

You will feel a definite throttle response difference between N and D-1. Mine always felt laggy though which is why I made a mechanical throttle

My first problem with the manual swap the right engine mount braket broke. I was trying to wheel spin and the clutch Is very harsh so my own fault plus the poly subframe mounts make the rear end a lot stiffer. I知 sure it痴 will be fine if I drive less harsh on take off

Wowwww, join the club except mine broke when driving hard over a roadwork trench and breaking one of the fixing bolts . Did you hit a pothole recently? That could have cracked or broken the engine mount



Broken engine support

That mount on the CLK55 engine I'm swapping in looks beefier. It's hard to verify w/o trying - but visually they look to have the same overall shape. Engine may go in next week - I'm going to install w/ the C43 mount and bolt up the transmission and get the engine sitting in the right place. When I have to temporarily remove the mount to then install the starter my plan is to see if the CLK55 mount fits. Might be an option for you.

It will fit but if you want to upgrade the mounts you should get these

be aware, if you go solid mounts, these big V8's will vibrate the hell out of you! I have custom poly mounts on my SLK55 and then ended up just doing it on the drivers side and it's still very shaky. You can see mine here:

This is very different from what you have done and we have different stiffness options available. Definitely will not vibrate as much as yours. Our softest option is almost undetectable until you feel the quicker throttle response. We have sold mounts all over the world from daily drivers to the fastest AMG's. We tailor the mounts to your needs

We would be happy to help you and we are the manufacturers of these mounts. The mounts are fully serviceable and are available in 3 different stiffnesses. Our softest option having near OEM feel in the cabin but increased throttle response. The stiffer you go the more vibration is transferred as you now. They are also designed 10mm shorter than a brand new oem mount. The engine mounts are $465 shipped in the USA. We also have a trans mount available for $175.

If you are interested we can send you a PayPal request. Here are some of the cars running our mounts

No issues with the exhaust when lowering the engine by 10 mm? Also, aren't the mounts on a slight angle towards each other and shortening them would cause them to be farther apart cross-car?
