I have a 07 Dakota QC automatic with the 3.7. Have intake and exhaust. I recieved the jet chip (stage 2) part number 90401S. I installed yesterday following the directions with unhooking the negetive terminal ect. When i turned the key all boxes lit up in the gear selector window. At this point i was kind of worried lol! I also noticed I had Drive but no 1 or 2. So i decided to take it for a quick spin to see if it was just the selector messed up. Truck ran and shifted good just cruising. If I put it to the boards it wouldnt shift and hit a rev limit at 4k rpms. I took the chip out and everything was back to normal. Im gonna try it again to see if it was maybe loose but i made sure it was tight.... If still problems Ill have to contact jet i guess... anybody else have anything like this happen? Anybody no the warranty on these chips through jet? Thanks in advance

 

Your quickest fix would be to buy a Dakota with a 6 speed. No moregear indicator problems.[8D]

 

lol that wasnt a harsh comment, i had problems with my jet chip too, it didnt work, i would contact them and tell them its messing everything up and they will send you a new one!

 

your right lol I shoulda got a 6 speed... Yea Ill try it tomorrow and if its no different its goin back. I wonder if maybe its just the wrong chip in the wrong box... I cant find a part number anywhere on the chip but it did fit in the computer soo i dunno. Thanks for the input

 

i dont no what the deal with all the problems some people are having with these chip. i did not have any trouble with the stage 2

 

must be alot of defective products

 

my chip clipped into place no problem and away i went. make sure it is for the 3.7 not the 4.7. also there should be a sticker on the chip with the part number.

 

also make sure you have it plugged into the correct port. second from the top, which is the white port

 

I had a few extra lights come on with my stage II also, I just unhooked the battery and let the system reset. No problems after that.
