F150 have a way to set it to tow with all four down. Only in the top trim levels. Don't remember the sequence. But it is in the electronics. Maybe the SD will get this ability too. Great for towing with a RV.

 

Usually you can remove a fuse or install a fuse which causes transfer neutral.

You're going to tow a Super Duty with an RV?

 

Nope. Just responding to the post that there is not a neutral position on the transfer.

 

I know it's not the easiest thing for some folks to do, but, in reality, the drive shaft comes out of a super duty truck ridiculously easy. Probably the easiest drive shaft removal of any vehicle on the road....I think it's 4 13mm bolts and 90 seconds of work.

 

I thought of that too, but most people would prefer to push the neutral button in the RAM then crawl under their truck. As easy as it would be, I'd prefer the button.

 

It is a little more than 90 seconds. 8 Bolts and a carrier bearing unless you are trussing the shaft to the frame. Plus getting the u bolts out of the yoke without damage to the threads. Older shafts take a 12 pt 5/16" box end wrench only. Not in everybody's tool box. All much easier in a shop on a hoist. I don't know why someone would tow a super duty unless broken. With no hubs to turn out on the 150 then there would be 2 shafts on the four wheel drive trucks. None lends well to the RV scenario mentioned earlier, especially if you drop a u-joint cap and have to clean, grease and line up the roller bearings. Lying in the mud on broken glass with traffic whizzing by at 75mph.

 

Might be easier to tow the RV with the Super Duty.

 

Do it one way on friday, and the opposite way on sunday. Nice to have a little variety to spice things up.

 

That's what I was thinking, lol.

On the F-150, and presumably the new Super Duty, you can achieve transfer neutral by turning the ignition to "on" without starting the engine, then placing the transmission in neutral, and then switching between 2H and 4H 5 times in 7 seconds. A message will appear on the dashboard that you are in transfer neutral. Turn the key off and you are ready to be flat towed.

Even if you did not put the F-150 transfer case into neutral, you could still flat-tow by removing only the rear driveshaft. Although the front axles and driveshaft would spin, the transfer case in 2H is not connected to the transmission (just like when you are actually driving it).

 

I keep my eye on some utube RV adventurers and one couple just started towing their Taurus this year. Before pulling it they have to start the engine and let it run a couple of minutes and then shift into each gear for a brief time to circulate the trans fluid. Then shut off an leave in neutral to tow. Repeat the operation every 200 miles. There may be a procedure similar for the F150 trans. There is also a dog clutch which my friend at a driveline company showed me once. It mounts to the frame and new driveshafts made to facilitate the installation. A lever on the side of the dog clutch engages the driveline to the transmission. Designed primarily for rv'ers who two automatic transmission cars.

 

Stopping every 200 miles to run your towed car sounds painful. The F-150 does not require this because the transfer case is after the transmission and not full time. The disconnect driveshaft sounds like it would work fine, but I'd rather just unbolt the thing for a really long drive. Then again, I'm in my 30's and don't mind getting under a vehicle. As I get older, that mindset might change! Of course the RAM neutral button solves it all.

Not sure if you are talking an older Taurus or the current design. We have a Lincoln MKS EcoBoost which is essentially a Taurus SHO. It uses a somewhat poorly designed PTU to provide AWD to the rear. I would never flat tow this vehicle. Maybe disconnect the rear driveshaft and put the front wheels on a tow dolly, but disconnecting the rear shaft is a massive pain. I think I'd either put it on a car hauler trailer or simply pick a different vehicle to flat tow. Of course, a carhauler is going to weigh probably 2200 lbs minimum and then the Lincoln is about another 4500 lbs...which puts it beyond the max towing of most gas powered RV's.

But I digress - this is about auto 4WD in the next gen Super Duty, which is now confirmed we will not be getting. However, it looks like we may have a way to get transfer neutral with the electric shift case, finally.

 

That just sounds like an excellent recipe for causing premature transmission failure. THat's unreal that someone would even have the intestinal fortitude to risk that kind of possible repair bill - especially if its not an 'emergency' situation. But, hey, if they've done it with success, good to know.

 

Hmm… not sure how that will happen. The ESOF transfer case is the same as prior years. If the F150 procedure for flat towing was available in the Superduty transfer case it would have been noted long ago.

As an aside, we have seen a number of F250/350 flat towed behind diesel pushers over the years, usually with a motorcycle or golf cart in the back. No Lariats, KR, or Plats tho, all have manual hubs/TC.

 

Nope, the transfer cases are different. Only the **** positions are similar. Ford stated early on transfer cases were changing, probably to accommodate additional horsepower.

 

i highly doubt we will see an auto 4wd anytime soon in our superduties. which is fine by me. when im driving in slippery conidtions i rest my arm on the shift lever with my hand ready to flick my SOF to 4wd and it doesnt bothr me at sall.
