Adding/enabling tow/haul mode

[Chad98]

I just purchased a 2014 ppv that I want to enable the tow/haul mode on so I can tow my 17' bass boat. My question is what do I need? Do I just need the civilian Tahoe gearshifter with the tow button? Is the wiring for the tow/haul mode already there? Or would it just be ok to use the transmission in the manual mode by restricting it to 5th gear? I'm new to the ppv so I'd appreciate those of you who know about them to chime in, thanks!

Interesting, I would like to know how to do these things too (I am planning on towing my CJ5 on a flat bed trailer.)

Actually, yesterday I installed the DIC in the car, and it shows a bunch of options to turn on and off, besides all the other info.

Would be cool (or maybe there already is) a compact list of these options/settings without having to dig all through the manual.

I too am curious I have a 2010 tahoe PPV.

I wished I had T/H mode too, but when I had my AFM tuned out I had him bump the shift points up a little, and it feels like it is tow/haul all the time. Maybe that's what he did, although there is no light. Haven't towed anything heavy yet, but it wouldn't be a big deal just to run it in M5 if needed.

I have a 2013 SSV, and like to know "all the options" I was talking to a GM dealer yesterday, about installing fog lights, Apparently there is a difference between a PPV, a Municipal Service vehicle, and an SSV. The fog lights can be installed, factory, on an SSV, but not on a PPV nor a "Municipal Service vehicle". I thought there were only SSVs and PPVs (but what do I know).

Well I have heard you just need a different gear shift and then I've heard you need that and a new cable, I've put in the impact so I have a hitch and the wiring was tucked away so I mean it's possible but I would like to make sure.

So mine is set up for towing, I was told, I do have the factory trailer brake stuff in the dash and I do seem to have a shifter with "some extras" I can take pics of that if anyone is interested.

I'm interested, a picture would help

Seems that it should be possible with a pushbutton simply installed in the dash. Just need to find a schematic for the switch, plus determine if they use a latching pushbutton, or a relay? I don't really need it on the end of the shift lever anyway.

Is running in m5 the same thing as "locking out overdrive?"
