I don't know if this has been posted but I couldn't find it. Those of us with the 4.7 seem to have a common complaint about the trans shifting too soon or the motor feeling sluggish in the low rpms. If that's a problem for you try putting the trans in tow/haul. It keeps the engine in its powerband by holding gears longer on acceleration and deceleration and utilizing engine braking. I've found that when the 4.7 stays in its powerband it's a completely different animal than it is when you let the trans do its pre programmed job. The only downside to using tow/haul it's your mileage might suffer a bit due to you keeping your foot in it!
Tow/Haul mode on the 13's doesn't change the shift points.
They have a very short shift out of 1st even with Tow/Haul turned on.
I've got to the point where i manually shift mine using that stupid unresponsive button on the shifter.
Dodge definitely needs to take lessons on tranny programing.
My company GM 3/4 ton with the 4.8LS is twice as nice to drive as my new Ram when it comes to tranny shifting
The short shift its what I hated the most. As soon as the engine would start to wake up the trans would shift and the truck would fall on its face. I can't speak for the 13's but the tow/ haul on my 08 holds each gear about 200-300 rpms longer and will downshift quicker or deeper when given throttle. It's a nite and day difference in daily city driving
Thanks for the info, brains! I recently put a SuperChips on my 05 4.7 and the tranny has definitly improved in performance. But the tow/haul button is a great way to help out. If you get any more great ideas in that brain of yours, make sure you share them with us.
