Change Ford 5R110 Tow/Haul to Overdrive On/Off ?
I don't remember seeing this discussed before so I thought I ask. My other van was Brent's 06 E350 Quigley with V10 and 5speed tranny. Here's my question:
5R110 trannys with V10s have a tow/haul button at the end of the selector while 5R110 trannys with the 6.0 diesels have a overdrive on/off button. If I push this button the tranny holds the lower gears longer which is what its suppose to do but what I want is to simply lock out overdrive from time to time. Perhaps ideally we all would want both features but I would be happy with the overdrive on/off instead of the tow/haul feature. (My SUV has both features so it couldn't have been that difficult to implement.)
Is there an easy, reliable and uncomplicated way to have the tow/haul button behave like the overdrive on/off button? If reasonably doable I know I would be trading away the tow/haul feature but I do not envision ever towing anything heavy. (Heavy being greater than 3500lbs.)
Thanks,
Ray

Many aftermarket tuners can alter shifting strategies, so I wonder if they can write a new tune to functionally replace the effects of the Tow/Haul switch with an OD cutout? I'd check with one of the customer tuners out there.

You can have 5-Star tuning make you a Tow/Haul program which locks out O/D.

Is it possible to do the opposite? I'd like the option of having both on my 6.0

I don't know. But the transmissions are exactly the same, except the labeling on the shifter, so it should be feasible.

Ray, what SUV has both, an Excursion perhaps?

None of the Ford's have separate OD and Tow/Haul buttons. The F-series did get Tow/Haul mode with their diesels, but the big customers of the diesel vans wanted OD-off instead.

Something does not make sense. It is my understanding that the 5R110 (TorqShift) has only Tow/Haul mode and no overdrive cancel switch and the E4OD/4R100 did not have a tow/haul mode, it only had an overdrive cancel switch.

Re: Change Ford 5R110 Tow/Haul to Overdrive On/Off ?
My 2008 Nissan Armada has a tow/haul button on the console. The shifter normally stays in 5 and can be selected to 4, 3, 2 and 1. I stay in selector 4 when I don't want overdrive. (I only turn 1500 rpm at 50 mph which is way out of the engine's torque peak.) I stay in selector 3 when I'm going up and down hills in San Francisco.
My 5R110 shifts up into 5th (overdrive) quickly. If I'm not on the freeway more often than not I will have to slow down because of traffic, traffic lights, stop signs, pedestrians, etc. This will force the downshift which is okay but you lose a tiny moment when it downshifts. If I could lock out overdrive and stay in 4th I can dart through traffic a little more readily. (Dart is a relative term, our vans are huge compared to most of the tiny cars around me.)
My 4R75E tranny in my other E350 has the overdrive on/off button. I often turn off the overdrive and stay in 3rd (direct 1.00 gear). Driving with traffic is more pleasant for me because I'm usually already in 3rd gear and know that I can dart around without the annoying momentary downshift delay. Staying in 3rd is not unlike my old C6.

I also thought that ...... I'll look into it more this week.
