    When backing up a relatively small incline, my truck, non hybrid struggles in comparison to anything I have ever owned. Not that big of deal until I was backing my trailer up an incline yesterday. While in tow haul mode it seems underpowered backing up. Otherwise the truck performs flawlessly pulling a trailer of 5000 lbs. Maybe I should have put it in tow haul + mode but it didn't come to my mind at the time. I haven't seen any earlier post on this. Is it lacking power in reverse or is it a learning curve with the turbos I have to get used too?

    They could have severe torque management for the reverse gear since I don't think you are really supposed to load them up that hard. Usually when I am backing my trailer up an incline I use 4Lo to destress the engine and transmission.

    What's your definition of struggle? I back up my 7k boat with no problem. There is an area that is a little high, 3-4", that the trailer has to get over, no problem there either. I do have to give it a little more gas over that area but nothing major. Tow/Haul in my truck makes it want to jump out of its own shell. I have used it while towing the boat but never in reverse. Don't know if it helps any in the sense of power.

    My fiance' has a short but steep driveway. When I'm backing out, I too noticed that I have to give it a little more gas than I'm accustomed to. My 2014 would climb half way up the driveway just by letting my foot off the brake. Oh well, too late to turn back now!

    it is about a 7% grade, I'll use the 4 lo from now on once I turn into the driveway. I agree, going forward this truck creates so much torque. I can be traveling at 70 mph with 5000lbs on back and it only turns around 1800 to 2000 rpms. Up a slight incline and it turns around 2200 rpm. I rented a 2021 Tundra and it too backed up with ease. Imo, it needs a lower reverse gear. Aside from that, I couldn't be happier with the way it tows. I'll purchase some new springs for heavier loads eventually. i'm watching the forums to see some results. I'd like to see results from a dual rate or progressive spring setup to keep a decent ride when not towing.

    How are you going to use 4lo and turn at all on dry ground ?

    just push the pedal down more , let the motor and trans work , rev that bitch up if needed, it won’t hurt it

    I had that problem and it ended up having to get the transmission reprogrammed, technical service bulletin 110-22 and 111-22, (which is on another thread) it's worth a shot, sure made a heck of a difference with mine. And I agree when backing a heavy trailer to use 4lo you have greater control in backing.

    I’ve never had to use 4lo backing a trailer , is that common? How do you turn at all on dry ground without binding the shit out of it ?

    I'm mainly talking about backing up when you're in soft ground or backing up an incline, engine and tranny don't have to work so hard, and if you set up properly you shouldn't have to make too many turns while in low, especially when you're backing close to 10,000 lbs, hard surfaces, no problem

    I usually do when I am trying to get my trailer into a gnarly boondocking spot. And I use 4Lo backing my trailer into the side yard with my Lexus GX because I can because it has the torsen center diff. Doesnt matter if I am on pavement or not.

    My F150 4Auto t-case is allegedly able to do 4Lo Auto according to Borg Warner, but Ford chose not to make that an option.
