GOAT Mode Question

Normal to slippery is fine, shift on the fly! Neutral and stopped to go to 4L

As noted above, you only need to stop and shift into neutral when going into and out of 4L.

Let me add 1 more thing. Do not go into the off road GOAT modes on pavement, never use 4H or 4L on paved roads.

Thank you!

And if you haven’t done so, go to one of the Off Roadeo events. Learn what this thing can do using someone else’s rig!

And just for funsies, here’s a great chart that illustrates the different modes & their settings.

OK...I'll bite. Why 4h a no no on pavement. I understand 4 low.

I think that it's still possible to bind something while turning on dry pavement.

Like Rookhoe mentioned, you can still bind things in 4 wheel drive. 4A is different, it is like "on demand" when a wheel gets power.
4 L/H lock all 4 wheels all turning at the same speed at same time, on pavement there is no "slippage" like on dirt/snow/ice. The outside tire turns at a different speed on a turn, and causes the bind.

I guess if you go in a straight line, it would be harmless, just do not turn on pavement in 4 wheel drive mode.

OK..we are taking dry pavement. So like in my old Jeep days if it is ice or snow you would be OK. I understand the other GOATs give you better control and choices. Thank You!!

4L/H doesn’t lock all the wheels. You have to turn on lockers for that.

That's what I was told as well. Oh well not going to get into another 6 vs 5.7 quart/liter dipstick conversation!! :0)

4L/H does lock all the wheels--it makes them all drive wheels..all 4 are now moving the vehicle with each capable of spinning at a different rate/slippage. The locker syncs both wheels on the same axle to turn at the same rate.

FWIW, I have used 4L on pavement---the pavement was under 12" of heavy wet snow, but it was on pavement.

Just to clarify, when I said not to use it on pavement, that should be dry pavement. Snow and ice on the road is different. :)

I used ChatGPT and asked why not to use 4 wheel drive on dry pavement, here is the response. 😁

Using 4-wheel drive on dry pavement is generally not recommended for several reasons:

1. Increased Wear and Tear: 4-wheel drive systems are designed for use in low-traction conditions, such as snow, mud, or off-road terrain. Engaging 4-wheel drive on dry pavement can lead to increased wear and tear on the drivetrain components, including the transfer case, differentials, and axles
2. Reduced Fuel Efficiency: Running a vehicle in 4-wheel drive mode when it's not necessary can decrease fuel efficiency. This is because the additional power needed to drive all four wheels can result in higher fuel consumption.
3. Handling Issues: 4-wheel drive systems are optimized for low-traction situations, and using them on dry pavement may lead to handling issues. It can cause a feeling of stiffness or binding when turning, and the vehicle may not handle as predictably as it does in 2-wheel drive mode.
4. Tire Damage: On dry pavement, the tires may experience increased stress and wear when the 4-wheel drive is engaged. This can lead to premature tire damage and the need for more frequent tire replacements.
5. Transmission Strain: Engaging 4-wheel drive on dry surfaces can put additional strain on the transmission. This strain may result in overheating and potential damage to the transmission components

Think of 4H and 4L as a locker for the transfer case... The front and rear differentials are still not locked. The left and right tire can still differentiate speed/distance between each other. You will have 50 percent of the power going to the front and 50 percent to the rear.

A differential locker will send 50% of the power it receives to the right and 50% to the left. Turning is a big problen when the "Differential is locked because one wheel has to travel further than the other (inside radius is smaller than the outside radius thus the outside wheel travels further but with the wheels locked they turn the same number of times. So you get wheel hop on pavement or any other surface that does not allow the inside tire to slip.

This is not the problem when the transfer case is "locked". the problem with the transfer case locked is MUCH more subtle. While the front gears are the same ratio as the rear gears they are NEVER exactly the same. There is a difference between how many revolutions the front tires are making relative to the number of revolutions the rear tires are making. It is a very small difference but a difference all the same. This means the front tires are traveling ever so slightly more or less than the rear tires. It is no where close to as dramatic as the difference in cornering with a locked differential. But just like that locked differential causes the tires to turn at the same rate while traveling a different distance... so to does a locked transfer case force the same number of rotations in the front as in the rear.... To make up for this difference the tires need to slip ever so slightly just like with the differential. If the tires can not slip the difference starts to create bind in the system. additional pressure is placed on the u joints/CVs, on the drive shaft, on the transfer case gears and everything in between. Because this is more subtle than a locked differential many people do not recognize that it is even happening. But it is. This simply accelerates wear. Things (the drive line) wears out faster.

Thanks for this!

Two questions:

1. Where did you score this chart?

2. What does “Trans.” hard/soft/normal mean? And would this apply to a manual transmission?

Yeppers, I agree with what everybody else has said.
