hey guys,
I have a 2011 Avenger sxt 3.6l
problem is code P0729 gear 6 incorrect ratio ( generic code )... the car has been dealer flashed with updated firmware but the issue is still there even though the dealer stated the problem was fixed but now I cannot even achieve highway 80-100 km speeds without over reving the engine to 6000+ rpm...! I'm hoping it's just a sensor issue or just a minor fix.. Question is has anyoneexperienced this issue and what was your resolve.?
