Very rough 1-2 shift, no DCTs, need help!
I noticed you talking about the MAF, if it is disconnected or not working properly it will raise line pressure through the roof. I've noticed this on mine once when I forgot to plug it back in, it was fine for awhile then start shifting REALLY hard, plugged it back in and it was all good. The reason it shifts hard is because when the MAF isn't functioning properly it reverts to a 'back-up' table which has the increased line pressure woven into it, so if you delete or 'disable' the MAF you have to change that table aswell so you dont have the line pressure issue.
