Greetings all, hoping someone can help me. I've had my '06 C55 for about 2 wks now and I've noticed something, but I am not sure if it's normal or not. When driving the car and apply gas everything seems fine, but when I release my foot from the gas the car feels really heavy/sluggish/slow. It's almost as though the transmission isn't allowing the car to roll naturally on its own. As a test I sometimes throw the car into neutral when going down a hill and I feel the car coasts a lot smoother and longer than when I have the car in gear and coasting. Sometimes I can even hear/feel the engine slowing the car down.

Does anyone else experience this? The car only has 37k km's on it. I picked it up from a dealership with a 4 year warranty. I didn't notice this the first few times I drove the car, but now it's all I notice.

Thanks!

 

completely normal. mine does the same. these cars did have a transmission issue, but it's not of this nature.

 

if you're in S mode the tranny helps brake the car, it will even downshift if you're driving aggressively. In C mode, the tranny coasts more when you let off the gas.

 

That is normal. I also thought there was something wrong when I first got the car and even asked the dealer about when I got the car serviced, but it is normal.

 

Yup this is normal, same thing here in S mode. If you put it in C mode you should notice it less.

 

It's all good, just engine braking.

 

There's a V8 in there you know

 

And a highcompression V8 too, wich really feels when you
climb off the throttle!

 

ok perfect! just wanted to make sure this was normal Thanks much for all the replies. BTW there's about a foot of snow outside my house. This sucks!!

 

One of things I had to learn to master was the downshift while coming to a stop that causes a slight buck (making your smooth stop not be so smooth).

 

oh man my passengers get really upset when i do that! one of the downsides of auto-downshift.

 

Just drive in C mode and all these "inconveniences" of the AMG Speedshift transmission goes away. In C mode, it behaves more like a typeical Benz slushbox does........priority is comfort and smoothness.

I only drive in S mode when there is little traffic, on the freeway (not in rush hour), or on the track. In day to day city driving, there isn't room to really enjoy S mode to its fullest (at least not in a major urban city).

 

you use "s" on the track? how does it compare to manually going through the gearbox? i was thinking about it and putting into consideration turns. if i'm in "s" coming out of a corner and i floor it, i'm sideways. i have much learning to do.

 

While C works perfectly fine, I keep mine in S mode all the time. There's something about that small extra lag? you feel when first starting out in second gear that I just don't like very much.

 

That is the way the car is supposed to act in Sport mode, true compression braking like a standard. If you don't like it, switch to C.
