Karim,

Thanks for the update. I can clearly see why the CL500 oil pan didn't work. The Crossfire/SLK has a very different suspension and frame and I believe my CL500 pan will fit fine. I mentioned before that I thought you might need exhaust manofolds from a C43/CLK500 or C55. I have all the mechanical parts ready to install in my car. I just didn't want to tear the car apart until I am sure about the electronics. I am attaching photos of my 2002 CL500 ECU and 2004 Crossfire ECU. You can see they are virtually identical. If you look closely it is very easy to tell which is the V8 and which is the V6. Let me know if your solutions looks like it will work for me. Thank you. If I use the origianl transmission, do you feel I will have problems with the transmission computer?
