I thought the manual and automatic used the same rcm. I’m not really a new tech vehicle guy. (77 Vette, 85 Ferrari 308, 89 Porsche 944 has less problems combined compared to the crossfire). Tech traced down all wiring involving computer and modules. They always say don’t go cheap when buying electronics. A new rcm through Chrysler is $434. Comes with a 70k warranty. If it goes bad again they will tow and replace free of charge. I will have about $2000.00 in towing and dealer charges all together. So, you automatic guys. I would buy a new rcm to keep on hand to avoid all the trouble and expense.
Sorry to hear that they sucked you dry, new RCMs can be had for half that, never go to a dealer.
I have a spare RCM and it cost me $45 on eBay. I soldered the usual connections and put it in to try it. It worked so I left it in, the original is in the trunk just in case. The one you purchased came from Mercedes and Chrysler marked it up a lot for their efforts. Who tried to fix your original RCM?
