I flashed a new tune, and then while the car was idling I hit "Trans Adapt Reset, Then Preset, and then Fast Learn" in the VCM Scanner. The car started idling 250rpms above normal. It did this for a couple minutes, and never dropped. I killed the engine, turned it back on, and then I put it in gear, but it would not move. I reflashed to an older tune just to see if I could get it moving. It worked, but now the car shifts very weird. It's like a hard, short harsh shift. Is this the transmission relearning itself or any idea what I've done?

EDIT : Redid the Learn procedure after realizing that I needed to actually log the PID and follow instructions. Fixed the issue
