Proper Method To Shift Into/Out Of 4H & 4L ???
 
I read on one website that the proper way to shift from 2WD to 4H was to :
(Automatic Transmission) Place your transmission lever into the neutral position, then place the 4WD lever into the vertical position.
(Manual Transmission) Depress the clutch, then place the 4WD lever into the vertical position.

Either way, you were disengaging the drive train before activating the 4WD capability.

This morning, I found another website that does not mention the need to disengage the drive train.

How to Drive a 4WD Jeep | eHow.com

It says, in part, " ...To shift from 2H to 4H, simply pull up on the 4WD lever with a smooth motion until it locks into place, releasing the accelerator pedal for a moment after you shift ... You can shift between 2H and 4H when the Jeep is either stopped or moving up to 55 miles per hour... "

Now I am confused.
I will be buying my TJ in the very near future.
I do not want to tear it up because of improper shifting.

Which is the proper way to shift in and out of 2WD, 4H & 4L?

Hope this helps, from the 2004 owner's manual:



Shifting Procedure
2H to 4H or 4H to 2H
Shifting between 2H and 4H can be made with the
vehicle stopped or in motion. If the vehicle is in motion,
shifts can be made up to 55 mph (88 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. Apply a constant
force when shifting the transfer case lever.
4H to 4L or 4L to 4H
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift
an automatic transmission to N (Neutral) or depress the
clutch pedal on a manual transmission. While the vehicle
is coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer
case lever firmly to the desired position. Do not pause in
transfer case N (Neutral).
NOTE:
Pausing in transfer case N (Neutral) in vehicles
equipped with an automatic transmission may require
shutting the engine OFF to avoid gear clash while
completing the shift. If difficulty occurs, shift the automatic
transmission to N (Neutral), hold foot on brake,
and turn the engine OFF. Make shift to desired mode.

172 STARTING AND OPERATING
NOTE:
Shifting into or out of 4L is possible with the
vehicle completely stopped, however, difficulty may occur
due to the mating teeth not being properly aligned.
Several attempts may be required for clutch teeth alignment
and shift completion to occur. The preferred
method is with the vehicle rolling at 2 to 3 mph (3 to 5
km/h). Avoid attempting to engage or disengage 4L with
the vehicle moving faster than 2 to 3 mph (3 to 5 km/h).

WARNING!
Failure to engage a position completely can cause
transfer case damage or loss of power and vehicle
control. You could have an injury accident. Do not
drive the vehicle unless the transfer case is fully
engaged.

I know this is old but any advice? I cannot for the life of me get it into 4L! Ill snap the level if I try any harder and I tried just like the above says to. I tried at the dealer with no luck but the salesman got it in twice by rolling just like I'm trying. I just changed all the fluids in everything and wanted to test everything out. Still no luck with 4L.

Have the trans in N
rolling at a couple MPH (no more than 5) (going slow, bump it from D to N)
from 4H
pull back and over, do NOT stop the transfer case in N, just keep right on a yankin to 4L.
Smooth, fluid, quick, motion all the way from 4HI to 4Lo. very important.
Now put your trans back in D and climb some shit.
No idea how to do this in a manual, so hopefully you have an auto and that was helpful.

I got it. Jeeps manual can kiss my ass!! I should of focused more on the shift lever than their directions. It's not just 4H to 4L firmly its push the lever in 4H all the way over to the right then pull it back and to the far left firmly! Without those two steps your going no where fast.

I guess jeep thought the diagram on the lever was good enough :whistling:

If you only go by the diagram on the shifting lever, then you would not know to clutch (on a standard) or place it in neutral (on an automatic).
Thanks for the explanations of how to properly shift using an automatic tranny.

The more often you do it, the easier it gets. Wheel the Jeep often and you won't even invest thought into shifting, it will just occur naturally ;).

Yup clutch in, stop overthinking & look at the shift lever. Shouldn't have to fight it too much... be firm.:thumb:

Here's a memory aid I always tell my Jeep customers: when shifting the transfer case, if you are going to pass through N then the transmission must also be in N (clutch iN on a manual). :thumb:

Oy
 
The sales guy told me that ALL shifts were to be done in neutral (obviously this isn't the case) and he also indicated that I should not be moving. However, the transfer case lever seemed a bit stiff and I wanted to get the hang of it. I'm afraid I switched to 4H in neutral multiple times while trying to get the hang of the lever but at a complete stop. Should I be concerned?

No reason for any concern, no. There is nothing wrong with shifting between 2WD and 4HI while in neutral; it just isn't necessary.

Sorry, I meant to say 4L. I stopped by the dealership to pick some stuff up and asked. I mentioned it being a bit stiff and they confirmed the original assertion that 4L can be done in neutral without rolling and that sometimes it just feels stuck.
