is they a way to have tow/haul automatically??

[Cummins Cowboy]

I have an '06 I was wondering is there are way to make my truck engage the tow/haul mode on the trans automatically everytime I start the truck, I like haveing the TC lock up at lower speeds even when driving empty. but alot of times I forget to hit the button until I have been driving for awhile

Yes there is. I have hooked up the ground input into ecm that activates the exhaust brake. This puts the transmission into a better shift pattern than the tow haul imo. It will hold the gears longer and lock the TC sooner after a shift. It also automatically downshifts the trans from OD to direct at about 40-45 MPH. It also holds lock up in second gear (manual shift) to about 20mph. I have the pin outs at the shop will post them later.
