I have an 07 SXT with the 3.5L and autostick. When I cycle up through the gears it stops at 4 and then goes to "D". I don't have a tag anywhere that specifies what I've got...on the door or under the hood. Thanks.
either way the 07 sxt's have the 5 speed nag1 transmissions which is what the R/T's, Daytonas and SRT8s use. The SRT8's have theirs beefed up though. For whatever reason it was decided to only show 1-4+D in the SXT's is beyond me...but the OP does have a 5 spd transmission nonetheless.
