There should be 2 more sub digits to that code as 00, 71 or 72, being it affected trans and data to cluster i would suspect a 71 for the hi speed data, at this point unless you have tech 2 to see which module/wire quit, remove trans connector and shove dielectric grease in trans connector and pcm connectors first, as they are in series so when one module stops data others in line follow. If battery seen a thresh hold under 9v it will also set that code
