I think that the trans adx sends different aldl mode commands to get transmission specific logging data instead of the normal engine data, but i haven't actually looked at it. The non-trans adx still has some trans info though. Looking through an E6 log it shows brake switch, four wheel drive low, range selector, shift solenoids, and a bunch of TCC stuff, along with vehicle speed and engine speed (so you could calculate torque converter slip etc).

Also note that you can(should?) load the E6 adx and do some logs before you try to start with an OD bin. That might give you some baselines to look at in case there are any initial problems to work out.
