came across some info here,that the tow/haul mode is kinda like a sport mode button.What perimiters does it change?Any changes with an auto and its shifts points.Is it safe to run it all the time?
That`s good info to know,So it seems out auto equipped Nitro`s are down tuned......for the sake of fuel economy?It likely also changes the shift map so it will stay in gear a little longer (higher rpm) before shifting. which would be why it seems peppier... max torque on the 3.7l is @4000rpm, and we rarely see that rpm in day to day driving.
Ah man,I hate when manufactures do stuff like that.Many vehicles have suffered from this irrational thinking.ex 1984 corvette w/ cross fire injection,intake manifold ports were only 3/4 of the size the could have been....power was cut immensely because of this....and why?So the next year tpi injection was first introduced would "prove" to have big hp numbers increase.Marketing at its best/worse I guessSo it seems out auto equipped Nitro`s are down tuned......for the sake of fuel economy?
That would be a big....YES!
For what you are doing auto is fine, unless the road is very hilly. If you were towing a heavy load long distance, I would suggest using the auto-stick.Not sure if this question belongs here or not, but I searched and can't find a thread specific to it. So the 3.7 has a tow/haul mode, my 4.0L doesn't have that but does have the autostick. So should I be shifting it myself when I'm towing? Or can I just leave it in auto and that would be okay? I'm only hauling brush, etc. to the transfer station here in town about 10 miles away.
You really don’t want it in OD while pulling anything other than an empty trailer, best to just let it do what it’s designed for it’ll save ur transmission but burn more fuelThanks for the info guys,my auto trans in the Nitro acts very much like a 700r trans in a vette I had,To me it seems to want to shift to early,goes into over drive and then is kinda boggy.I played around with it on the way to work this morning.Feels way better to run in tow/haul mode till you get to 50-55mph then hit it and let over drive kick in.Very much like the 700r,same thing that was run in D till the 50mph mark came then shifted it in over drive.Its def more peppy in this mode:Racing:
