i am new to the xj world , as i use to have a tj so bare with me , is the aw4 supposed to upshift even if you have in in first gear , mine just shifts as i had it in drive , maybe at a little higher rpm. but on the trails i find this annoying as i cant seem to keep my xj in a nice rpm or it bogs down . is this rite or no . i just assumed it shifted by itself from 2 to 3 . thks
