No noticeable difference when tow haul mode is on

I have a 2009 Toyota tundra to two wheel drive with a 5.7 liter engine. It has a button to turn tow/haul mode on and the indicator light turns on and off in the dash. I do not seem to notice any difference with the shifting schedule however when I drive with it in tow haul mode. I've driven other vehicles with this feature and it's been very noticeable. Like I said before in my truck there's no noticeable difference. Has anyone encountered anything similar to this? I'd appreciate any advice on what to check. By the way, I have drive selected when trying to use the tow haul mode.

Thanks

 

Are you driving normally?

If you mash the throttle, it'll try to bury the needle before shifting. If you are going down hill and let off the throttle and the truck is still speeding up (or not slowing down as quickly as it thinks it should be) it will down shift and act like an engine brake.

Basically, you can't drive it normally and expect it to act different with T/H on. It's designed to give you access to more of the power band and control your speed better.

I use mine when I'm on hilly/twisty roads or if traffic is thick.

 

Try this mode.

Yep, I've tried it driving normally and towing, don't really see any difference when it's on or off.......

 

Unlike your 2018, throttle response doesn’t change in tow/haul on our older 2nd gens, only shift points under certain conditions.

 

Can you elaborate on that? What the 2nd gen tow haul mode actually does? Right now it seems that it's not doing anything (check out link below where the driver makes the comment that he really can't tell any difference.....)

Any info is appreciated.....

 

My tow/haul moves the shift points up on the rpm gauge. You really only notice it under heavy load or heavy acceleration.

I've noticed that my tundra leans on some engine braking even without tow/haul or crusie control on. I notice it every now and then, my tundra doesn't just coast free.

I've owned some cars that use engine braking when on cruise, like my Sienna.

 

On my ‘08, I mostly notice delayed upshifts when accelerating up a hill, a tendency to hold a gear longer before downshifting when trying to hold a steady speed up a hill, and a bit more aggressive downshifting for engine breaking downhill.

Where in the world are you and what kind of terrain do you drive on Matt? If you’re on flat land, I can kinda see noticing nothing. Get in them there hills…

 

Guess I'm just expecting it to make a much more more noticeable difference, like some other vehicles have. Thanks for the feedback! Guess I need to hook the trailer up for a test drive.......

 

My 13 will engine brake when I press the brake pedal. I really like this feature since the "smart" brakes always have me coasting until the last 50 feet and turns it into a hard brake.

You can also drive it like you stole it from a stop or slow roll. It should try to bury the needle before shifting.
