jscott645 Posted January 31, 2023 Share Posted January 31, 2023 I purchased my 2012 Sport with 80k miles just last week. My wife and I took it on a multi-state 1,000 mile+ drive. Just yesterday we got some snow here and and after leaving work, a wrench light appeared. I did use the manual trans option for 30 seconds while going (slowly) down a hill out of my office parking lot. Now this this wrench light won't go away, and I am unable to use the manual option on my trans. Other than not being able to use this feature, my car is running just fine. The only thing I have changed on this car is the cabin air filter ? Scanned my car and found the following codes: U0073 U0100 I've already cleaned my cars battery terminals, and replaced the battery (was just 2 years old) Any tips or ideas of what to check? 0 Quote Link to comment Share on other sites More sharing options...
WKelley Posted February 1, 2023 Share Posted February 1, 2023 U codes are communication codes, they may need advanced scan tool work. Write those codes down and remove the negative battery cable for 30 seconds or so and see if that turns the wrench off. Otherwise you will have to get those communications codes troubleshooted. It will take a good scan tool to do that, those bluetooth phone app scan devices are not gonna cut it. 0 Quote Link to comment Share on other sites More sharing options...
jscott645 Posted February 3, 2023 Author Share Posted February 3, 2023 (edited) I figured it out. I scanned it with an ABS scanner and found codes U0114 and P0819. I was suspect of the shift lever assembly so I went to my local pick and pull and picked up a used assembly from a Mercury Milan with Select Shift for just under $25. I wanted my interior pieces to match, so I pulled the small chip out and installed into my existing assembly. It was located on the right hand side and was held in by one T20 screw. Now I have no codes present and my SelectShift works as it should. Wrench light is also gone. Removing the gear shift assembly was fairly easy. All you need is a flat head screw driver, basic sockets, and some trim pulling tools. I disconnected my battery just to be on the safe side.
