The Titan tow mode (at least in the Gen1) raised the shift points for 1st/2nd/3rd gear, and activated downhill transmission braking which meant a downshift occurred when you applied the brakes at a certain level on a downhill grade.

I suspect it does the same on the Gen2, but read your owners manual to see for sure what it does. My guess is, unless you're under load, you won't really be able to notice any difference.

Kind of. It raises the shift points for both up and downshifting, for the lower gears (1-3 on Gen1 5spd trans), but it also will drop shift you if you brake, to add braking. It's one of the best tow modes I've had on a truck, and I've seen several different brands.

 

[dubyam]

No. It's all about speed versus brake pressure. Get a good running start down a steep grade, and dig into your brakes, and the Titan (if it still has the same programming as the Gen1) will downshift a gear or two.

 

[dubyam]

Not on the Gen1. My tow mode switch just lights up, but there's no "Tow" light on the dash or in the cluster anywhere.

Dubyam are you saying the tow mode only actually works in the lower gear range?

What I'm saying is that on the Gen1, it raises the upshift RPM for gears 1, 2, and 3, and the downshift points are also moved upwards. I don't know what the corresponding changes are in the later 7spd trans. May affect more than 1-3 on those.

Owners manual is useless

Well, I'm guessing you haven't read it. That statement is false on its face. Read the manual. It has more info than you know.

I looked up the 2018 owner's manual online and read through all the sections with the words "tow mode" in them. It's the same verbiage as my 2011 manual, almost to the letter, with the exception of the description of the "tow mode light" in the instrument cluster, which isn't on the 2011. All the info is there if anyone wants to read it.

Dubyam I read the manual long before I posted here, and your right lots about towing a trailer. But if you will read you will see I am not talking about how to tow a trailer which i have done for years and years while you were still in diapers. I am talking about tow mode and how exactly it is suppose to work. the manual as I stated is useless when it comes to this topic, section 2-70 is the only section I can find on this all it tells you is the green light comes on in the dash DA I already know that. I am looking for an explanation as to what it actually does to the engine transmission combination. Since you have found all this info out would you be kind enough to post it or at least the pages where this info is located.Hey maybe I missed it.

It's already been posted. The following information is right there on page 10-60 of the 2018 Nissan Titan Owner's Manual:

"Tow mode includes the following features:

● Grade logic — Adjusts transmission shifts when pulling a trailer or hauling a load up a grade.

● Downhill Speed Control (DSC) — automatically downshifts when driving down a grade with a trailer or heavy load to help control vehicle speed.

Driving the vehicle in the tow mode with no trailer/load or light trailer/light load will not cause any damage. However, fuel economy may be reduced and the transmission/engine driving characteristics may feel unusual."

So maybe you need a little remedial reading while you worry about how long it's been since I was wearing diapers (about 50yrs, if you're dying to know). So, as I said before you pitched your little insults at me, it's all there in the manual. In English. Easily readable. Right in the section entitled "Trailer Towing Tips" in the Technical and Consumer Information Chapter. So instead of spending so much time insulting me (after I've already told you what Tow Mode did, even before I told you the manual was full of good information after you complained about it) maybe you should spend a little time working on your reading.

I'm happy to help. Just don't accept my help then complain about it. I could just leave you ignorant.
