I just purchased my wife a triple black 2004 CLK500 AMG package with only 108,000 miles on it for $3500. On the way home the Transmission wouldn't shift out of 1st gear. So we need a new transmission. I want to know if a W220 transmission like a 2004 S500 is compatible

I forgot to mention. The car needs a battery. I was told that the transmission may have jump in stay alive mode due to low battery voltage

Getting stuck in gear (usually 2nd, not 1st) is "limp mode". Before looking to replace the entire transmission, I'd get the codes pulled (generic OBDII scanners won't do it - you need a tool capable of directly reading TCU codes, like the dealer's SDS). A somewhat common issue on this transmission is a bad conductor plate that is not terribly expensive and even a DIY job if you are so inclined.

I read on the forum that both of codes can be caused by the Transmission conductor plate. So if I repair or replace the conductor plate will my problem be solved?

Those are generic OBDII codes pulled from the ECU (engine control unit). You need the MBZ-specific DTCs pulled from the TCU (transmission control unit).

Reviving an old thread.

I just went into limp mode - pulled the P0715 "Turbine" code. So this is generic? My independent shop has told me his scanner read 90% of codes, I wonder if these would fall under the 10% that he doesn't have a tool for.

Is there a write up on the plate install? Would you replace that and the sensors (both)?

--Prior to limp mode - Hard shifting at times, very intermittent. Then sometimes I would start the car and notice it would not shift "limp mode" I would shut it off and restart and it was fine. This time it would not switch over and I notice the W/S button would not work either. Possibly helpful, I thought to have noticed this more after a rain or wet roads and this particular time was a couple hours after a deep car wash cleaning.

What car and what model year? If you have the 722.9 transmission, this will be a dealer job as the conductor plate is part of the drive authorization system and requires live SCN coding. If you have the 722.6 5-speed, then you can DIY. You can buy a new conductor plate and replace it by dropping the pan.

The conductor plate has the sensor built onto the board. When you replace the conductor plate make sure you replace the pilot bushing as well.

You need to remove the transmission pan, transmission filter and shift plate to gain access to the conductor plate.

That kit is everything you'd need to replace parts-wise. I am not sure if that's a good price or not - you might check some of the other trusted suppliers - autohausaz, rmeuropean, pelicam mboemparts, etc. to compare. You will need fluid, and that is going to be the 236.14 spec (the 236.11/12/13 is no longer mad - 236.14 replaces those). Shell ATF-134 is a good one that is normally easy to find. You will also need a dipstick.

How long or how many miles would you drive on this? I did clear the code.

I am moving next saturday and I doubt ill have time before the move to tackle it. Its 15-20 minutes away.

Is there a way to tell for certain it is the whole plate vs. the adapter plug?
You can check the adapter plug first.

Flip the locking lever down and pull the adapter plug out. If its wet with transmission fluid, check the TCU for contamination also.

I use Ardeca UNI-MATIC ATF. I use nothing but Ardeca in all my vehicles since they have a distribution center local to me. For the 7 speed you have to use the MATIC+Z7 oil.

For all MB parts. I buy from parts.com or ECSTuning.com.
