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.

Keith, I do know more, but both my eng short hand and why I don't come
by as often...
FWIW...my consulting team worked on the, then, next gen hybrid and the
automatic redesign. We were called in late, as they were having thermal problems
Found that they wanted the controller inside the automatic and use the
ATF as coolant :E
Talked shop with several of their tranny guys and did cover T/H. So,
yes understand 'their' genesis for the T/H function (warranty) and
most of the stuff it does (PSI is only one aspect). They did NOT want
to have two electric motors, but space was at a premium...boy is that
automatic going to be pricey to fix...
Ordered the 'F60' option when ordering my Suburban. For those who
don't know...the F60 option is the snow plow prep package and begets
the 1 ton front torsion bars, etc.
Since my rear diff assembly is 'almost' identical to the 1 ton dually
of that year (the difference is in the brakes...cylinders are larger
bore and the MC has larger bores, proportioning valve is different, etc)
Tongue on cheek call mine a K3500...
Turtle is an old salt and knows his stuff. He has more patience than
I, as I'd rather have been able to order mine with manual 5 speed.
What bothers him is the kind of stuff I dislike about automatics
and the 'new' bells and whistles for the non-manual owners...
