T42 trans module - Cannot read the trans on a 2007 Trailblazer SS, but can read/write the ecm without issues. Anyone else have this issue? Using the latest Beta, tried the std version, vehicle has 12v+, tender on the battery and tried without, pulled radio fuse also since a/m radio installed. Car does have an a/m alarm system, but I have another one at the shop with the same alarm and I can read it no problem so don't think that is the issue. Support ticket was sent in also on the issue but it's a holiday weekend.
