Tow/Haul and starscan question

[tp0d]

I have an issue with how fast the tow/haul mode downshifts on a downhill acceleration. I use my truck as a service vehicle, and I do a lot of city driving, as well as highway. City driving is my main concern, as Pittsburgh is a very hilly area.



What I would like to do, is see if theres a way in starscan to only allow the truck to downshift in tow/haul mode -only- if my foot is on the brake. If I let off the brake, downshifting stops. yes, i`m aware that I can stop a downshift by slightly pressing on the accel, but some hills I would -really- like to just exh brake all the way down.



Theres a few hills that really really jam on the truck, like over 3000rpm when the downshift occurs. drives me nuts.



Anyone have any ideas? Or a number for dodge engineering? (laff)



thanks

Software changes can not be done with a scan tool. BTW the starscan will not work with 2010.

There are no software updates for the trans that I am aware of at this time

shifting

What I like to do and it works for me is to leave it out of tow haul, and shift it when you want to. That way on a long downhill it stays where you want it to . Also you can brake if you like and no down shift. or you can down shift when you need to .

H & S Performance has a transmission program for the 2010. Don't know exactly what it does, but they are altering the shifting. Nice guys to talk to, maybe they have what you're looking for. Quote from website:
* Boosted line pressures
* H&S Adjusted Part throttle shift points
* H&S Adjusted Full throttle shift points
* H&S Adjusted Part throttle shift firmness
* H&S Adjusted Full throttle shift firmness
* Adjusted Torque converter lock-up speeds
* TCM Adaptive memory reset
* H&S Adjusted Torque Management Tables
* Custom tunes available FREE for download HERE
* Easily returned to stock in minutes for dealer visits
* Custom tailored to mate with H&S engine tuning
* No TCM removal required, all tuning is done through the factory OBDII port

looks interesting, powder, but seems I have to get a tuner module to try it. . not lookin to void my warranty on a service truck. may have to give em a call to see if its possible to download somethin right thru the OBD... hmm
