Have you considered picking one up from a junk yard? I think as long as it's from the same year it doesn't have to be programmed.

Thumbs up

No didn't consider junk yard would prefer a new one or at least a remanufactured one so I wouldnt end up in the same situation again. Any advice and suggestions are appreciated. Also if you know of any online sites I can order from that may have the part please let me know

They usually go bad because the TCU gets contaminated with transmission oil due to a leaky connector seal plug at the transmission. TCU goes into lock mode to avoid further damage.

Replace the plug, take out the TCU and clean it with electrical cleaner. Let it dry, and do a SDS reset on the TCU. It MIGHT work, it worked for me. Alot cheaper than getting a new TCU and getting it programmed.

I had the tcm replaced car runs fine now it was located under hood on passenger side fender wall part itself was nearly 1200.00 and dealer would not even sell it to me unless they were installing and programming with part diagnostic and programming cost me nearly 1700. Thanks to all for assistance

pretty much you're screwed because anybody that wants to buy a transmission control module is going to have to get it from the dealership you can't just buy anyone that has to be coded to your VIN of your car and they won't sell it just to you it has to be a certified Mercedes-Benz mechanic

jennacyde why did you bump a 12 year old post ? And your info is totally wrong . The s600 used a 5 speed and the Tcm is not coded to The car so you can swap in any used Tcm from a similar car . I suggest you don’t post wrong information if you don’t know what you’re talking about
