So i was thinking... Can you swap the tx15b transfer case (3 modes) with the atx14b transfer case(auto+ 3 previous modes). [/quote]

Anything's possible, but it's not going to be easy. The main harness is different between the two models, for starters. I would imagine the ECM programming would be different and possibly the instrument cluster, as well. I have an SE and an LE; seems like an awful lot of work for not a lot of gain!

Have you noticed better acceleration with auto ?

Postby **smj999smj** » Fri May 15, 2015 7:23 am

No. The only difference the AUTO mode would make during acceleration from a stop is if one was accelerating in a condition that would cause the rear wheels to spin. In that case, the transfer case would start to apply power to the front axle. Unless you leave from a stop at wide open throttle all of the time, the AUTO transfer case doesn't give you any benefit. The best use I've found for it is when in conditions of light snow or when I'm on roads with slick areas where you wouldn't need 4WD all of the time, but it's nice knowing the 4WD will kick in if I should hit a slick spot and need it.

I've found myself wanting the auto mode at times too. Its a bit of a pain in the a$$ to continually switch in and out of 4wd depending on conditions, as you aren't supposed to exceed 60MPH in 4wd, and also your low speed manueverability really sucks when 4wd is on.

But its still great to have it when you need it.

We barely have snow around here, but it would nice when going uphills on wet roads (and they are a lot) without spinning wheels and vdc kicking. Anw thnx guys

I thought you could travel any speed in 4hi?

Postby **disallow** » Fri Jun 05, 2015 12:09 pm

that is a big negative, at least on the manual 4wd system. 62MPH max!

manual meaning like transmission? I have the selector switch for 2-4wd, but no auto selection. I didnt think there was an issue with driving at any speed in 4hi, knowing that turning radius is decreased and not to drive in 4x4 on dry pavement...

I'm embarrassed to say but I drove in 4hi for about 200 miles on dry pavement at highway speeds 60-90 mph.

I was coming home from a ski trip with snow covered roads for the first 10 miles then once I was off the mountain I forgot to switch back to 2wd. I guess all the booze and skiing got to my head a bit.

Thankfully the Pathy handled my mistake just fine.

I also find it strange that the disclaimer for driving using 4Hi/Lo was far more on the tires than the drivetrain itself. If you look up the youtube from Nissan regarding the owners manual on the Pathfinder, it doesn't say anything about drivetrain wear, only tire wear

Yup, I wasn't worried about my tires, only worried about the drive line windup that could occur. I brought my car to my mechanic the next day and he said everything looks fine. I did have to replace a u-joint about 2 months later though.

Straight from the owner's manual, page 5-20:

"The 4H position provides greater traction.
Avoid excessive speed, as it will
cause increased fuel consumption and
higher oil temperatures, and could
damage drivetrain components.
Speeds over 62.5 MPH (100 km/h) in 4H
is not recommended."

I don't see anything about tires.

no not manual transmission. Pathy's don't have that in North America anyways.

I am referring to the dial which I have to manually turn to 4HI to achieve 4WD.

Just to add to the confusion, I'd like to ask a question.

Switching from 4WD to 2WD while in motion is okay right? I usually do it when I get on the highway and hit around 40mph.
