What is the purpose of no clutch starting in 4 low

I know if the transmission is under wanter, you don't want to depress the clutch. But, my question is, how would you take off? I'm guessing you just put it in gear, and as your cranking the motor give it gas so the minute it fires up it takes off? I was just curious in case I ever find myself in this situation

That would work. I've started cars in first, even three speeds that had a broken clutch pivot fork so that I didn't have to call a tow truck. Driving it to the service station can be accomplished even shifting without the clutch both up shifting and down shifting. Approaching traffic signals slowing down to avoid stopping so that the engine doesn't have to be restarted while in gear. It can be done. I've driven up to 40 miles like this.

To answer the title of the post, I'm guessing that putting the clutch in would allow abrasives in between the clutch and pressure plate causing excessive wear afterwards.

Been there done that. I had a '91 Dodge Shadow. The clutch went out. I started it in first and got it home by shifting without the clutch. You just have to feel the right rpm's and slide it out and slide it in to the next gear. No grinding whatsoever.

So if i'm ever in water, I just put it in gear, and while starting it up give it gas so it jumps the minute it turns over?

Jeep in a low gear, probably 1st through 4th in 4 low but definitely in 1st in 4 high or 2 high, then crank the starter, the jeep will buck a couple of times, then move steadily but if you jump all over the gas, the bucking will be more sustained. I would say, starting is the hardest part. After is stops bucking, and running steady if on pavement and able to coast come up on the rpms gradually and while at high rpms with the engine under no load or near no load slide it out of 1st, let the rpms come down gradually with the stick up against second gear. When the two gears mesh, the shifter will move into second.

If the jeep is in mud I don't know how effective starting it with the clutch engaged will be at keeping crud off of the clutch. My question to the folks reading this thread is will water and thus, dirt infiltrate the clutch easily or would it take time for it to get in there? If it takes time getting in there, then not sitting in the mud for too long is advised. If the jeep is stuck in the mud, then getting pulled out will certainly take time. By that time, would the clutch area be wet and if so, how would one go about cleaning it out with fresh water?

So, basically, what maintenance issues are there with the clutch if you think it has been infiltrated with mud?

Actually you will love the feature if you rock crawl.

Have you ever been pointed straight up seeing nothing but sky. Where you are on the verge of flipping all the while afraid to roll back several feet to loose the progress you've just made if you press the clutch when it all the sudden stalls?

Been there, done that. Press the clutch and you roll back or worse the released tension makes you bounce. Start without pressing the clutch and you don't. Saved my butt at least a couple times.

Maybe the Rubi is different but my Sahara won't turn over in 2H (not sure about 4H, haven't tried yet) unless the clutch is in, 4L it will. BTW this is a question not a correction cause I'm a newb, thanx.

Hope this clears it up. Four-Wheel Drive Models Only:
In 4L mode, this vehicle will start regardless of whether
or not the clutch pedal is pressed to the floor. This feature
enhances off-road performance by allowing the vehicle to
start when in 4L without having to press the clutch pedal.
The “4WD Indicator Light” will illuminate when the
transfer case has been shifted into this mode.

Nissan Xterra had thE same sys, called clutch cancel (button) to use on hill,IF ENGINE DIED, so you could still keep one foot on brake and one one gas--

This all doesn't detract from the instruction that ___

NEVER operate the clutch while in deep water/mud, because it'll allow water/mud to penetrate the clutch disc and "RUIN IT"--

I thought I read the manual from cover to cover but I missed that one. Thanks folks, that will definitely come in handy.

JIMBO, is it that critical? I'm certainly going to pay more attention to it now.

Well, it all depends on HOW DEEP the water/mud is

If the WATER is over 2' deep and you use the clutch, you can "BAKE" it out by using the clutch intermittantly for 15/30 times in the next short time after you're out of the water, in other words USE THE HELL OUTTA THE CLUTCH to "BAKE" out the moisture--however

If you use the clutch in 2' ++ mud--"ADIOS CLUTCH"

Now Although I've never done this in mud, there is a possibility of running thru a creek 2' +++after the mud and flushing the disc with water/clutch use (in the water), but

As soon as a Green peace/Sierra Cub member here's about that--OhOh-OhOh

Thats why I got an Auto !!!

Years ago I was on top the Sierras 9000 ft above Lake Almanor (west) and my Dodge Power Wagon 5spd--LOCKED IN GRANNY 4lo

Thats a story !!

Thats why I got an auto !!!
