I'm wondering how many of you use the "TOW/HAUL" mode on your trucks. I'm assuming this only a function with newer trucks but I imagine it's a feature across the board with the various makes. I have a 2013 Ford 350 and there's a little button that puts it in tow/haul mode. The ride is significantly different but I don't know that it's necessarily better. It almost seems like it takes more RPMs to move up to the next gear. Is that normal? Is it better for the truck? Does it not really make a difference? Hmm! So curious.

Tow/haul alters transmissionmshift points to aid in moving a load off the line. It also helps keep the transmission cool by firming ip shift points. Both good for your transmission.

T/H should be used when hauling,especially heavy loads.It changes the shift points on the tranny among other things that are beneficial to the vehicle.I use it at all times while towing.

I use it to hold a steady speed when going downhill on high-speed roads. We have a lot of mountain grades here in SoCal - The Grapevine on I-5, Cajon Pass on I-15, Mountain Springs Grade on I-8. With tow haul, I can do them at safe speeds with just that initial tap on the brakes to engage the tow-haul.

Your owner's manual should tell you how/when to operate the T/H Mode. Mine says to engage it when I'm towing approx 15,000 pounds.

Yes I use tow haul mode. without it Id be dogging it with the GM shift points.Also probably a hotter trans due to torque converter lock up.I can only speak for GM.2006 silverado,On GM the shift points are extended to keep the RPMs up in the torque band. Will not go into OD until 60-65 mph.. ( I ride in 3rd anyway. Any fuel loss is well worth a new tranny.).Also increases line pressure for firm shifts when towingThe torque convertor stays locked on second gear on up. Locked up TC keeps trans cool.The alternator comes out of fuel save mode and pumps the full 14.4 volts.There is no down shift mode on the gm of my year. The slow down when accelerator is released is that the torque convertor stays locked. Ford and the like I believe actually down shift.
