Do the 5.3 Envoys and Trailblazers have the "Tow/Haul" feature?

I know they are difficult to find with the 5.3 but they are out there. So...do they have the "Tow/Haul" button/feature that's offered on the Tahoes and the Yukons?

They do not..

Thanks TollKeeper.....I think that finally makes up my mind. I'll start looking for a Tahoe or Yukon. I just like the size of my standard Envoy. The Tahoes and Yukon's are a little bit bigger but smaller is better when I'm exploring the canyons and sandwashes of the local desert.

2002-2009 Chevrolet Trailblazer Towing Capacities

The Chevrolet Trailblazers were made from 2002-2009 and are making a comeback in 2021 but I decided to focus on towing capacities for the 2001-2009 models only in this post. I tried to break down

All the tow/haul mode does it change the shift points, mostly hold a gear longer while accelerating and not upshifting to overdrive if towing heavy when you have to keep the throttle up to keep the speed. Also downshifts while in cruise to engine brake when going downhill. All things you could do yourself.

I have sometimes wondered if tow/haul altered the line pressure a bit?

I'd have to pull my old HPT files from my Avalanche and compare. IIRC those were the same. Other other thing it did change was the torque converter clutch lockup.
