So playin this weekend and when going up steal hills and let off gas jeep rolled backwards and died. Is it because it was in drive and rolling backwards? As soon as it stopped it started right back up and ran great until I let off and it startes to roll back and died again. It runs fine and has no codes. Its an 09 with the superchips tune. Any help would be great.

 

Anyone?

 

Never heard of anything like that before on fuel injected vehicle.
How much gas in the tank and how steep of a hill.

sent from the slow lane

 

Tank was full. Hill was steap but others did it too and stayed running. I have never heard of this before and really dont even know where to start looking for problems

 

Auto tranny?

Probably the shallow sump sloshing the tranny fluid to the rear, causes you to slip. It was one of the big reasons RK introduced the deep sump tranny pan (since discontinued). Happens on steep climbs. It was probably stalling after you rolled back and the tranny caught again.

I've seen this happen a few times now.

 

Is an auto tranny but id been up hills like this before and never had a problem. I would think if tranny was starving out it would of done it the other times too. Maybe not. I dont know. Thank you though

 

Try and over full the sump with fluid and see if that helps. You won't be able to get enough in there to hurt anything.
