Shift to 4H while driving?

[TurtleAdventure]

Omg!
Never in a million years would I even consider going from HI to LO while in motion!
Holy smokes.
No; do not do that.

AHHAHA I should have been more clear. I meant going from 2 to 4Hi. HAHA

Jamming in 20 year old truck into 4 low while driving makes my belly hurt thinking about it.

Well here's a question for y-all .....

A) How many people here in this thread have an auto with electronic J-shifter and can successfully shift Hi/Lo while moving with zero grinding?

B) 2nd question .. how many miles do you have


Me .... 1997 Auto Limited. 251K miles. I use the button to shift 2HI <--> 4HI while driving with no issues, ever. But I must stop and turn off the truck when shifting the transfer case 4HI <---> 4LO or there will be grinding. I used to be able to do it on the fly, many years ago just fine. Then I had to stop and go in transmission N but could leave the truck on. Now I to turn off the truck as well to experience no HI/LO, LO/HI grinding sound.

:bigok:

I can shift from 4h to 4l while moving under 10 mph, and am in the 230k range with the electronic shifter. Sometimes it will want to grind, and I'll back off. Other times it will slip right in. I've found that if I keep a bit of pressure on the lever (but not enough to cause grinding), it will eventually mesh together, just like shifting a manual without using the clutch. Basically, once the input rpms match the transfer case output rpms, the gears mesh right together and there's no stopping required and nothing grinds. Same for disengaging.

But most of the time, I stop and put the transmission in neutral before shifting to or from low. I engage 4h while moving all the time though, and rarely engage it while sitting still.

some people have more $$ in their pocket then me.....seriously,
and they have a few years of age on me ( or under me) where they don't mind switching out transfer cases on occasion because they have time and a 12 -pack of wrench lubricant...you shift from 4h to 4l while moving....good for you
I would not even try...because I don't have the bucks...the time...or ...well I do have wrench lubricant

I stopped reading after the first page.

2000 J-Shifter. I shift from 2H to 4H in loose traction situations regularly below 50mph. Always a stop from 4H to 4L.

What do I win?

You get to keep driving your truck as is

50 mph is too high to go in, ok to come out. 25-30mph tops to go from 2h to 4h. You win nothing! LOL :cheers:
