RPMs limited in 4L reverse?

[Maximus Gladius]

"Because of the additional gear reduction when in low range, engine RPMs should be kept under 2500 (remember the planetary is turning at 4 times that rate 2,500 x 4.0 = 10,000 RPM). Severe transfer case damage can occur if this RPM warning is not observed "

That splains it!

Can you please provide the source for this quotation you posted? Your response is appreciated, but again does not address the question I asked. I am simply trying to find out if it is my truck that is rpm limited in 4L reverse, or this is normal for all gladiators.

It's from the disclaimers with after-market transfer cases - like this - you'll find it here -

It's not from Jeep or your stock transfer case -

This information is from page 169 in the 2021 owners manual. No reference is made to causing damage to the transfer case at rpms above 2500, only a caution about over speeding the engine while in 4L. Now back to the original question. ?

What’s the original question again? I thought it was “does anyone else’s do this” which was answered “yes”.

That bit about the gear reduction, engine speed 2500, etc. was for after-market reductions. It's from their documentation, not Jeep.

I have found ZIP about Jeep and any limits. I was shopping with my wife most of the day - she gets impatient this time of year, so no messing around with the truck........ so wasn't able to test my OVERLAND for this behavior.

So far only Maximus Gladias has responded to the original question that was posted. I’m sure that all who responded had good intentions, but those responses have not addressed he original question so I’ll try again.
When my gladiator is in 4L REVERSE, the rpms are limited to 3500, and if I let off on the accelerator a bit, the rpms are further limited to 2500. Has anyone else experienced this in their gladiator? Is this “normal” for all gladiators. If you can, just put your truck in 4L Reverse, see what happens and report back.
Best wishes to all!

This refers to the original question I was try to have answered. Maximus Gladias was the only one who responded. His response was helpful but not very specific if he had try 4L reverse under more controlled conditions and if the rpms were specifically limited to 3500 and then further to 2500. Also, I would not consider 1 response enough to call it “normal” for gladiators in general.

Here is another attempted where I tried to explain my question
“Maybe I still am still failing to describe the situation fully. When I put the truck in 4L Reverse (no off road+, no lockers, no other changes) and then begin to back up, once 3500 rpms is reached, the truck will not go any faster. If I let off on the accelerator a bit and then try to accelerate again, rpms are further limited to 2500. The ground speed of the truck at 3500 rpm in 4L Reverse is about 6mph, and at 2500 about 5mph. These are my results on a level gravel road.”

To answer my original question, you would need to put your truck in 4L reverse and report on your results. No one seems to want to try this. Until that begins to happen, I guess the question will remained unanswered. I have no ill feelings toward anyone and do thank those of you who took the time to respond.

I think it has been answered, and you ae a manchild.

Well, I guess we just disagree on that point. Sorry I could not communicate clearly with you.

 

[DankjeeP]

No, it's apparent you just want attention.
There are lots of people to give it on this sight, even some commies believe it or not.

Thank you for your interest in this thread. Do you have anything to add that would add information that pertains to my original post?

Really?
I guess my point is proven beyond any reasonable doubt, sheesh does anything ever sink into your dense skull?

Holy ... I'm done

It's been done, he posted it. His results were the same as yours. You can ask again and the the results will be the same, you can ask again and the results will be the same. I wonder if the results will be the same or different if I ask one more time. You never know. Keep trying. Never give up. Someone is going to give you whatever answer you are looking for eventually maybe. It's been answered, but it doesn't hurt to ask again. Surrender and acceptance is the first step to recovery. Good Luck.

There’s some type of limiter in place in certain scenarios. I remember doing a coolant flush on the first engine to get the assembly sands out and at one point I rev’d the engine to get the temps up to activate the thermostat and the RPM’s would not accede 2000. It’s like the same limiter in 4L reverse or forward.

But “red lining” it is possible when driving in manual shift, 4H.
