Saving the Clutch

Two cell phones work great for the above video.

I got to use 2WD LO today when I brought the camper home. It was my first time towing anything other than a U-Haul car carrier. It is SUPER tight at the top of my driveway. I finally got it turned around and backed it in easily with 2WD LO. I can't imagine what it would have been like in 2WD HI.

My wife is a clutch slider with my Cummins/NV5600 tranny combo.....even with a empty truck.
The Cummins has a zero throttle launch so no need to rev and slide the clutch when empty of backing my fully loaded 16k GN tri axle stock trailer around cattle pens/ crowded stock yards or hilly pastures.
With a 6.29 or 5.63 : 1 ratio reverse/1st gear the Cummins will idle backing up a steep bank.

I don't have 4 miles, but I do have a 500 foot paved driveway that is very steep in spots and one car wide. I need to bring it up top and swing the truck and trailer around. It levels out at the top, but not enough to prevent me from having to maneuver with the trailer on a fairly level spot but with the truck on a steep decline. To make things more interesting the trailer will be parked where I have asphalt millings (a hair better than gravel). I worry about traction so I'm going to try to keep the truck on the pavement as much as possible when getting the trailer in its spot.

I was goofing around with the 2LOW kit today and it works as designed. I have less traction when backing in 2LOW vs. 2HI for whatever reason. I brought the truck down a really steep part of the asphalt millings and it would back itself out in 2WD but with the 2LOW engaged it just dug itself a hole with the left rear tire. I'm not too concerned because I'd never bring anything but the 4WD down there but it's just an observation.

I've over analyzed this situation to death but I think I'm good. I'm bringing the trailer up here on Saturday so wish me luck...

I was 4-wheeling with a friend about 45 years ago. We were in his K Jimmy and were in 4LO on some dirt and degraded rock. Kept spinning out, even a low speeds. Shifted to 4HI and we had no problems. Seems the slip of the torque converter allowed him to "feather" the throttle a bit more and kept the tires from losing traction.

I was at a campground with our, then new, KZ FW. Packed dirt and sand drives. I had to back up a slight incline into our site and, even with the weight of the FW on the pin, started slipping. Dropped into 4HI and backed right in.

I use 4-low a lot...but, hate the stress it puts on the drivetrain. Not fond of the “crow hopping” when in a tight maneuver. There are ways/methods/components to disengage the front drivetrain, it’s only a matter of money.....a goodly portion of it! memtb

I use 4LO when towing the mile off the "main" road into our boondock site. Not because I couldn't tow it in 4HI or even 2wd, but the road's a bit rocky in spots so this helps me to just creep over the rough spots at idle. As soon as I get past the bad spots, I switch back to 4HI, then 2wd when I'm maneuvering. I also use 4HI on the dirt road coming in, as it's got washboards and, even with the weight of the pin, the back end can hop a bit. Never over about 25 mph for the 4 miles in, and no really sharp turns, so I don't feel that it's putting much stress on things.

Friend of mine, his wife loved her manual transmissions, but was burning out clutches every 20k miles. She used to control her speed, by slipping the clutch.

My wifes garage queen, SRT Challenger, I stalled it in front of 50 of my car buddies, took a lot of ribbing on that one. One suggestion learn to drive a manual trans, except my daily drive at the time was a fiesta stick :) The clutches were SO DIFFERENT, that I just let it out too fast.

I did have fun one day, finished talking to my friend who was parallel parked... and my foot just happened to "slip off the clutch", while tiny bit higher engine RPMs. Silly 275 tires must have hit some water or something on the road :)

In my Dodge, turning the front wheels is very difficult when the front is engaged. Especially in tight maneuvers.

Get a 4 low disconnect kit. It is well worth the $$$.

I love my 2 Low kit; I use it every time I back my trailer into tight spots. It is tight getting into my back yard and using the 2 Low feature makes it MUCH easier on the clutch. In the case of an automatic, it will definitely be much less strain on the transmission.

Overall I would say it is one of the best modifications I have done to my truck.
