Two simple things I would check:
1) how's the battery voltage? I've seen all kinds of gremlins from low voltage effects on the computers
2) run without the unit plugged in. I had a blue tooth ODBII that caused all kinds of havoc on the transmission (ramming in and out of lock up at a stop light, etc) I was sure the tranny was shot. Unplugged the adapter and went right back to normal.

I will try this on the way home today and report back with the results.

I have changed mine regularly. And at decreased service intervals. 15k fluid and 30k I change the filter.

Well I unplugged my sct from the unit and from the ob2 port. No change still happens. Last night I put my tyrant tow tune on the truck and unplugged the GH SOTF switch. Truck shifted perfectly fine this morning. I am going to drive it a few days and see what happens with the tyrant tune.

Been driving on the tyrant tow tune for 325 miles and transmission has been flawless. Shifts better than with the GH SOTF tunes.

My gh 2nd gear lock up sotf tunes shift way to fast and you can feel the tc lock and unlock in just about every gear when you are kinda cruising around when on and off the pedal. I always use trailer tow anyway since i like the shift points and trans breaking and it shifts consistant as ever when doing that.

My torque converter does not lock til 4th. Locks in 4th at 32mph shifts to 5th at 35. It's annoying.
I too find myself driving around with the EB on all the time as well.

So after 500 miles of driving on the tyrant tow tune it has been flawless. I wish it didn't wistle so dang loud at idle. So I loaded to GH SOTF tune back on the truck and did the transmission relearn. Drove it this morning to work and sure enough the slam is still there in 4th when the torque converter locks. Like running over a 2x4 in the road. I think I should have bought the tyrant SOTF tunes. However idk if it would be any different. I know these two companies worked together on the SOTF tuning.
