Hi.

I’m not sure if this is the correct place for this thread, but it’s related to all three Transmission, Axles, and Gears and more.

I have a Rubicon with Off Road+. I can read what it states in the manual for what happens when you use this in 4L and 4H. I’ve read and seen many videos, and experienced off road myself a few times where you want to drive with both feet to “keep from shocking and loading” to “have some resistance on the drivetrain”. This gets complicated with a manual clutch on my CJ7.

However, with the Retirus (my JTR) being a manual transmission, when I put it into 4L, there is no clutch work involved. I have to admit it’s a great feature. It crawls forward, and I give it gas only and usually don’t touch the brake until I want to stop.

This leads us, finally, to my question: when the Off Road+ button is engaged, does it give the desired resistance on the drivetrain without putting my foot on the brake? When I’ve used the Off Road+, the engine feels like it works harder to move the wheels forward or backward, as compared to 4L without the Off Road+ engaged. Is this my imagination?

Or, is the tech, as described in the manual: "Engine/Transmission Calibration: Rock Crawl and controllability focus, change in shifting schedule when rock crawling, pedal calibration shifted to de-gain and low range, operates at lower vehicle speeds" - is this calibration putting the desired resistance into the drivetrain? Change in shifting schedule, I’m assuming, refers to automatic transmissions. Pedal calibration shifted to de-gain - I’m not sure exactly what that means - perhaps the answer to my question? Or is it even a more subtle thing that is happening?

I’ve also read somewhere that driving with Off Road+ saves stress on the Gladiator’s parts (but can’t I remember where - it didn’t come up in a search here where I do most of my reading). I guess I’m looking for clarification on what exactly the Off Road+ button does, and whether or not it is enough, or further brake pressure is desired - especially keeping in mind that I have a MT.

The pedal de-gain means they use a lesser throttle position (less fuel) for the same pedal position in Off-road+ than would be used in normal driving. Being a drive by wire system, this is easily done. This is much batter than the old days of trying to feather a pedal within a small portion of its full range to get the slight adjustment you need.
