So I'd have to shift to M and back to D each time I came to a stop. That doesn't sound appealing.Smartstopstart.com makes the module. It’s $140. When you shift into M mode, you have to use the paddle shifters to shift. The auto stop only happens when you come to a stop and if the car determines the engine is not needed to keep the temperature. To defeat you would toggle into M as you com to a stop. The engine will now stay running. When you pull away either toggle back into D it use the paddle shifters if you wanted to stay in M.
