For those of you with a similar tow vehicle do you just use the tow/haul mode or do you also lock out a couple of the higher gears?

Thanks

That depends a lot on how heavy the trailer is, how fast I am going and how steep the hill is. I generally use tow/haul for anything over 4,000lbs but override with manual shifting at times. I never just lock out some gears because there are always some times when coasting that I want the highest gears available. Sometimes with heavy loads on steep hills I force it to downshift all the way to first.

2019 Expedition MAX, towing a 7000 pound boat. Tow/Haul, and let the auto tranny decide what gears are appropriate. It isn;'t in 10th very often. Usually 8th or 9th.

We have towed several thousand miles with that setup. Always use tow haul. Did use manual shift some in the rolling hills, but usually just let it do it's thing. Towing a TT about 7200 lbs loaded.

Never been been in real mountains so can't speak to to that.

I put it in tow haul and go. I don't overthink it, the computer can monitor thousands of inputs and make decisions in split seconds; no need for me trying to out think the computer.

When I want to "play around" I shift my Silverado when towing while watching the tach and speed closely. Otherwise, tow/haul...superior to me shifting!

05 suburban 5.3, 11 Silverado 4.8 V8, with 4 spd OD's.

never liked how the tow haul works.

truck not lugging, normal shift points working fine, transmission not constantly
hunting for the right gear I use OD.

Load heavy enough to notice performance I will keep transmission in 3rd (drive)
to prevent lugging the engine and the transmission from hunting (constantly shifting)
for the right gear which over heats the transmission.

will downshift going down on a grade if needed.

knock wood 181,000 miles and 198,000 miles. only replaced 1 ignition coil and
1 water pump.

Bunch of changes since ‘05, 32. Transmissions are now 10 speeds. My transmission has never lugged in tow/haul.

2018 f 150 with 3.5 and 10 speed. Tow haul mode and lock 9 and 10 out. Only on long gradual downhill grades will let it shift into 9th.

I monitor my engine and transmission with torque pro app, and have not found any advantage to manual downshifting with it. This is coming from a former Ram 3500 owner who would only drive manual transmissions because I could do better than the autos. That was then, now....... Maybe its not the trucks are better, maybe I am worse.
