Tow haul button
I have a 04.5 duramax 3500 and I'm not sure when to use the tow/haul button on my gear shift also using this will it help my MPG? Thanks.

That's like saying that automatics "were invented" for people who don't know how to manage a manual transmission. Even with the TOW/HAUL on, you still have to manage the transmission! Let me guess, you jumped right in and knew exactly how it works and how to use it and you came up with this conclusion? The op asked a question and he got some good answers except when you need to feel good about yourself, you throw that language in there. This site is supposed to be for help and ideas, advice etc. Sorry all but it gets old having to read replies to post such as those that are demeaning to others because someone had a question that seems simple to others! To the op, a rule of thumb is that anytime you hook a trailer up or put 2 or 300 lbs or more in the box, push the tow haul on. Changes your shift point, less strain on tranny.
The Tow/Haul button/function was invented for those who do NOT know HOW2 manage
their automatics by manually shifting....to do down a gear or more...to hold a
gear longer, etc
Pretty soon the OEMs will increase the cost/price and complexity to manage folks
who will NOT and/or do NOT understand HOW2 use the Tow/Haul button.
My guess is electrical. Strain gauge and/or when the trailer plug has
a connection. The TV will then automatically switch on the Tow/Haul function for
the Automatic transmission
