Hello,
A few days ago I bought a Chrysler Crossfire Coupe 218HP with an automatic transmission manufactured in 2004.
Driving this car gives me incredible joy.
But I would like to get advice on one thing. Namely, not every time, but usually when switching the position of the shifter on the automatic transmission, you can hear a grinding sound.
This also happens when starting the car, i.e. when I slowly release the brake pedal, sometimes you can also hear a grinding sound.
Please help.

 

Hi, is the grinding sound coming from the transmission or the wheels - usually, grinding is associated with wheel bearings. Yours might just be starting to go bad.

Thanks for your advice, Jerry.
I'm trying to figure out if the problem is with the automatic transmission or the rear drivetrain.
I'm going to a local mechanic in early January who only deals with automatic transmissions. That's where I want to start looking for the cause of the grinding.
But I am also writing on this forum to get some further advice.

 

Congrats on your purchase. The best advice many here can give is to find an independent European car mechanic that knows the Benz SLK-320. These folks would know all of the Crossfire drive train. Good luck!

Thanks for the tip, GraphiteGhost.

 

Just a thought; Do you hear the sound in the front or back? Do you have original or after market wheels? If the wheel bolts are too long they might be rubbing on the emergency/parking brake parts.

 

The wheels are original.
A grinding sound is heard in the back.
My Dad said it wasn't a drive problem, but rather that the sound when releasing the brake pedal came from the brake pads.

 

I agree with your dad, probably brake noise. If a car sits for a while this is common, especially in damp weather. You could have the pads checked, just in case. The brakes do have wear indicators to warn you when the get worn down.

 

How many miles on the car? maybe the rear brakes need replaced.
if for some reason some one used the wrong lug bolt on the rear wheels,,, the bolt hits the e-brake cable and makes a grinding sound.
remove a lug from the back and one from the front ,make sure they are ALL the same, doing one at a time ,u do not have to jack the car.
as said above rust on the rotor (overnight) can grind as u touch the brake peddle, but only until u wear off the rust then it goes quite.
if no any of that you could have a heat shield rubbing the drive shaft.
jack the rear off the ground both wheels,,, start the car hold the brake start the car , put in drive SOWLY release the brake while u or your dad is looking for the grinding sound.
also look for any thing on the front of the engine that may be touching anything. jim

 

Thanks Jim for your advice.
It's winter in Poland now, so for now I'll wait until spring when the temperature is higher.
Then let's see if the grinding also occurs when it's warm.
So for now I'm assuming that it's the brake pads that generate the grinding when releasing the brake pedal.

 

if the pads are bad then yes that would be correct. , when grinding occurs push the peddle lightly until the grinding stops OR the car stops then yes you need rotors and pads. jim
