I’ve had my Wrangler JL (2020 Willys) about a month now, and shifted into 4h just to know the feel (so I wouldn’t be figuring it out when I “needed” it). Had a lot of difficulty shifting the transfer case so I ran it by the dealership today, and they did it the first time, and now it transfers smoothly. With the vehicle in drive and rolling, I shifted it down into 4h. On the instrument cluster, the 4h indicator (in the tachometer) flashed orange a few times then became solid. I shifted back to 2h and the 2h turned white. My question is...is the 4h flash before solid normal and part of the indicator? I can’t find anything in the manual or online that says yes or no....

No flash here. And it's always hard to shift in the beginning. The more you use it the looser it gets:angel:. I'd actually be concerned that after taking it to the dealer, it's now easy to shift. But, that's just me:like:

It’s not as easy as the transmission to shift (had to take from dealer stock to qualify for the 0% financing, so it’s an automatic, which is the only thing I don’t like about it) so it still takes some force, but not like it was. The service guy at the dealership took it through to 4l and back up following the book. I’ll do it again today and see what happens. Thank you for the heads up...

I'd just keep working with it some. :like:

The flashing only means the 4WD hasn’t engaged. That’s all. You want to make sure the light indicator stays solid.

As per why it hasn’t engaged, that depends. Wrangler 4WD shifters are notorious for their temperament; the 4:1 transfer case on Rubicons is more difficult than most. The owner’s manual explains the right procedure. Once you get the hang of it it ain’t too bad.

Good luck.

You could buy an aftermarket shifter. They come in various colors, sizes and shapes.:CWL:

I've always put the transmission in N before shifting into 4 H. Not sure where I picked that up. I still do it even though the manual says its not needed.

Have you checked your tire pressure? are all 4 tires close? The manual states that can cause a delay in engaging 4H:

Shifting Procedures
2H To 4H Or 4H To 2H
Shifting between 2H and 4H can be made with the vehicle
stopped or in motion. The preferred shifting speed would
be 0 to 45 mph (72 km/h). With the vehicle in motion, the
transfer case will engage/disengage faster if you momentarily
release the accelerator pedal after completing the
shift. Do not accelerate while shifting the transfer case.
Apply a constant force when shifting the transfer case
lever.
NOTE:
• Do not attempt to make a shift while only the front or
rear wheels are spinning. The front and rear driveshaft
speeds must be equal for the shift to take place. Shifting
while only the front or rear wheels are spinning can
cause damage to the transfer case.
• Delayed shifts out of four-wheel drive may be experienced
due to uneven tire wear, low or uneven tire pressures,
excessive vehicle loading, or cold temperatures.
• Shifting effort will increase with speed, this is normal.

I’ve seen mine flash and then go solid. Looking at the wire diagram I believe the flash is the signal that the FAD is engaging and it switches to solid when it is engaged. I think it could happen quickly or may take a bit depending on a lot of factors, temp, speed etc.
