i have a new silverado with a 1000lb trailer + 2 snowmobiles to pull this year
and i noticed that the tow mode revs somewhat higher..should i use this for
towing all the time?is this hard on the truck?i plan on keeping this truck for
10 years and it will be used mostly for towing this trailer in the
winter...most towing is highway and some elevation,thanks for any help...
Tow mode firms the shifts and shifts more into the power band.
2k lbs. of sleds isn't that heavy of a load for the truck but if your towing
in hills the firmer shifts are less heat building. My '99 Yuk auto. adapts
to tow loads, I'd rather have the switched mode myself.
Main thing is to service the trannie every 25k and I'll last a long time.
"anything you say can & will be misquoted & used against you"
Yeah, my manual states that the Tow/Haul mode in my '04 simply changes
the shift points so that the shifts are more "consistant". You might
notice that you'll expect it to upshift here, or downshift there...
where in normal mode, it's always bumping up and down gears as you
get on an off the throttle.
I have some software that gives me access to the trucks computer, and
the line pressures for both modes are exactly the same.
It's completely up to you whether you want to use it or not...
I think it's a LITTLE harder on the truck when you don't have a load
on there that would benefit from it, but I really don't think it's
abusive. I think it's probably a litle abusive if you don't use it
on a large load, and you've got the tranny running up and down the
gears on hills.
What I have noticed when towing in tow mode in OD the torque converter stays
locked even when shifting to 3rd. I know that conventional wisdom says that
you should stay out of OD when towing but if the TC stays locked, what's the
Marc Westerlind stated he has software to access the trucks computer, what
do you use this softwar with? Lap top or what? Or are you talking about a
Hypertech or Superchips programmer, or a different programmer.
