Thanks for your reply. I was able to read and save E38 data but I am not able to find T42 in autocal for data retrieval. Was I miss a step during setup?

I went with AutoCal and EFILive V2 Email Tuning. I drove about 1 hour and was able to gather Data Log and Tune File(e38) for 2008 Yukon Denali XL. However, instructions says to collect transmission data but I can't seem to find the option in Auto Cal. What did I miss?
