Where is the TCM located on a 2013 Mazda 3i SV?
 

AT light and check ending light came on. Had Autozone check the CEL and they said it is a dealer code (U0101). Did a search online and looks like I will need to replace the Transmission Control Module, but I couldn't find any info where the TCM is located. Wonder if it is in the same location as the previous generation (i.e. under battery) and if it is fairly easy to replace (i.e. no reprogramming required). Thanks
