Over drive Lockout add on?

Hey everyone, I have a 2018 F53 V-10 chassis under my Winnie Vista.
Is there an aftermarket device to lockout the overdrive"6th" speed in the tranny?
I miss being able to select how far the tranny would upshift on our 2001 DP with Allison tranny.
My only option on our new rig is to push the tow/haul mode button which still shifts into overdrive. I want to be able to hold it in 5th gear. If I drop it into 4th with the shift lever the RPM's are way to hi.
In some hilly or up hill runs a 5th gear max would be great & help my mileage also.
I'm not looking to hop up the drive train, just want more controle.
Mikee

Ford V10 can run all day at 4,000+ its not a big displacement diesel, you may want to look into 5 star programmer which allows the v10/6speed to hold gears longer on grades. Great people at 5 star! Give them a call.

Both 5th and 6th gears are overdrive in the Ford 6 speed transmission. If you shift it to 4th, it won't go there If it could overspeed the engine.

Turn on " Tow Haul " and on a down hill run tap the brakes and it well downshift to the next lower gear.

So you use your foot instead of your hand to manually shift.

I set Tow/Haul and Cruise Control and enjoy the ride. I don't worry about shift points or RPMs. Gas Milage ? could you make a measurable difference in a days driving.

I'm complaining about the up hill runs, down hill isn't an issue.

Cruise control in the hills sucks. Motor goes from 2000 rpm to 4000 rpm back & forth, geez it sucks. With out cruise I can feather the gas pedal & make it drop to 5th gear and it goes up the hill just fine. The programming for the cruise sucks. Speed set at 65 start up a small hill & speed starts to drop cruise control brain waits till the speed hits 60 mph then drops to 4th. If I could just tell it to drop to 5th.
It doesn't matter if I have the tow haul on or off. I sure miss my old Allison,"Don't miss the cost of maintaining that diesel rig tho"
Iv'e done several test. If I keep the cruise on in the hills I get 6 MPG.in my part of the world. If I work the gas pedal & drop to 5th gear my mileage increases to 7.5 mpg.
I'm one of those guy's that check the mileage every time I fill up or top off.
Iv'e had the rig for a year now & learned how it likes to be driven and how it doesn't, at least for now.

my understanding is the 5 star tuner fixes the problems you are trying to address.

The 5 star tune fixes the 5th to 3rd downshift of the older 5 speed transmission.

I have the 6 speed, V10 in a 2017 class A. I also tow a heavy Honda Ridgeline.

I have not experienced any of the loss of 5 MPH on cruise or the dropping to 4th gear, from 6th, shifting issues that you are experiencing.

I use cruise control to maintain a constant speed, rather then increase speed down hills, only to bleed off speed on the way up.

I wish all drivers maintained a constant speed on highways instead of passing the same vehicle over and over again.

Overall gas mileage is only accurate at the end of the trip, but its such a small part of RVing that I don't track it. I enjoy the drive.

My 2016 6-spd reacts the same way when on an incline while in cruise. The way I would describe it is that the cruise control waits too long into the climb to drop to 5th from 6th, and as a result, there's not enough engine power to maintain the RPM's even in 5th. In its determination to aggressively get back to to the selected cruise speed, the tranny will then very quickly downshift again to 4th to regain RPM's and speed. Had the downshift from 6th occurred sooner, the RPM's in 5th would have been sufficient in many cases to at least hold, if not increase, speed in 5th to the end of the climb. As a result, on many occasions now, I get out of cruise on an incline and induce the drop myself to 5th earlier in the climb to avoid a further drop to 4th. That works many more times than not. For me, it's not worth a decision to get a 5 Star solution, if one is available. For others it might be worth it.

I understand exactly, and it's frustrating. When I come to an incline while using the cruise control I tap my brake to take it out of cruise and use the gas pedal and it drops down into 5th gear at around 3,000 rpm (normal runs at about 2,200 rpm); smoothly and without fuss and muss goes up the incline, then I press resume and go back into cruise. It's stressful and irritating for it to rev up to 4,000 rpm just to maintain an exact speed going up a hill. By manually using the gas pedal I can maintain speed by dropping down into 5th early in the climb. I know the higher revs do no harm to the engine, but it does fray my nerves.
Thanks,

We have the older 5 speed tranny. With it to cancel the cruise all you have to do is hit the resume button. Then hit it again when resuming cruise is desired. I used to tap the brakes also and feather the gas pedal to avoid unneeded shifts until I learned this Resume button trick. I donít know if the six speed tranny has the same feature, but worth a try.

Just one additional comment on this item. After I get out of cruise I also, as wog099 described, use the gas pedal to induce the downshift to 5th. I'd rather, if I could get it to react, do that while still in cruise. From my experience, it's very hard to induce that downshift to just 5th while in cruise. I can do it on some occasions, but it's like pulling teeth; and most of the time, that move to 5th is followed very shortly after with another to 4th. I presume this is because the cruise control is still fixated on getting back to the prescribed cruise speed, whereas when not in cruise I'm feathering the gas to just start regaining RPM's again. I think it would be much better in these heavy MH applications to be able induce this 1-gear downshift on demand while in cruise, much like when not in cruise.

Just curious if 6-speed owners have also found this to be true. I'm home and the MH is parked for the time being, so don't have it out to test it. I did check my Ford manual though, and it only speaks of hitting the brake to temporarily drop it out of cruise. Would be nice if there was a button to drop out of cruise when needed.

I am heading south Sunday.

If I remember, I will see if hitting Resume will cut the cruise control.

My understanding is that pressing the Resume button to cancel cruise doesn't work on all of the 5 speed transmissions.
There are a few that it works on, but many claim it doesn't.
I know that it didn't work on my old 4 speed.

I'm going to learn something from this (and probably feel like a dodo), but my owners manual has the following statement,
"Canceling the Set Speed
Press COAST or tap the brake pedal. The
set speed does not erase."
I swear I have used the "Coast" button, but thinking it would decrease speed and when you release it I expected it to maintain that speed. It didn't work like that, so I never use it. If it works to take it out of cruise like tapping the brake; I will feel like a real dummy who has learned something!
Twinboat, can you try the "Coast" button to see if works like 'tapping' the brakes? If not I will try it next time I drive.
I appreciate the original OP posting this as it has always bugged me too. It would be best if the cruise control only dropped down one gear, but that is an extreme rarity when that happens.
Thanks,
