Tow/haul

Ok I traded in my 2008 Tacoma which I dearly loved for a 2010 4WD 5.7L Tundra SR5 TRD off road with tow pkg. I have a 1963 4wd Chevy Suburban I've been restoring. The Tacoma wasn't upto hauling it and a dbl axle trailer. The Tundra will like a champ.

So there's this tow haul button on the dash, I've read the owners manual and all it says is to use when towing or hauling a load. Gee Really?

What I'd like to know is, what does it actually do? Change shift points, no overdrive, give 500 extra HP or what?

Thanks

 

Biggest thing it does is change shift points. It holds in gears longer, really helps to keep the tranny temps down. I always used it when towing. Also its really great going down grades, when you even just tap the brake it kicks down a gear. Just always make sure to use a good trailer brake controller.

 

Congrats man! I did the same thing, traded my 08 taco for a 10 tundra TRD O/R, I love it!

 

I traded in a 2008 Nissan frountier for a 2014 tundra TRD with tow package 5.7

 

I traded a 2012 Tacoma in on a 2015 Tundra. I plan on putting a slide in camper and hauling my boat.
Tried the tow/haul on the boat and it does change shift points and the down shift is great. I really don't need it just for the boat but had to try it out.
It also changes throttle response. It is a lot quicker to respond to your foot.

 

If it is like the 1st Gen Tundras, it also locks out OD. Though only being a 4-speed auto the button is simply labeled to turn OD on or Off. Not sure if it does that also on the newer ones. 1st Gen trannies are not happy towing big loads in OD (Toyota bought me a new tranny at 35k). Haven't towed without pushing the OD Off button since and she is still happy at 120+k.

 

It doesn't turn off OD any more it used all gears in tow mode with boat in tow. We are on flat land and it will hopefully drop out of OD when we tow in the hills.
This 2016 has six speeds and the last two are both OD's.

 

Mine is the 5.7. If you pull up the transmission gear ration 5&6 are both overdriven. They make up for it by using 4.30 to 1 rearend gears. Plus the 400 ft pounds of torque doesn't hurt.

 

I used mine; hauling a full 6×14 trailer, full bed, and full cab. All the way from FL to CA., 3300 miles in 2 days! Never knew I had any extra weight.
I'm a 2nd gen., 4.7, rwd.

 

I traded my 1999 Tacoma for a 2010 Tundra so I could pull my 22 1/2 ft. camper. I like my Tundra but I sure wish I could have kept my Tacoma also. The Tundra pulls my camper without any problems, I'm just not used to it yet. It has tow/haul but I didn't know how to use it. I will try it out the next time I go camping. This forum is helping me get to know my Tundra, Thanks guys!

 

Not sure about the newer Tundras, but most vehicles (regardless of make) suggest not towing any real loads in OD as the gear itself is not all that strong. Tow in OD you risk blowing up the tranny . I know with my 4.7 which has a single over drive, I get the same or better mileage towing in the 1:1 gear than I do towing in OD. Not sure which gear that would be in the new Tundras in mine, 4th is OD so regular towing is in 3rd. With my new Taco which is a 5 speed auto, 4th is 1:1 and 5th is OD. I believe 4th is 1:1 in the new Tundras with the 6 speed.

 

I was going to trade my 05 Tacoma in on my Tundra but the wife said no way in hell are gonna get rid of the Tacoma!.....third world problems.

 

Welcome from CO. Came from a 09 Taco. That 63 Suburban has got to be pretty cool.
