question for rock crawlers

So I picked up a YJ that had been rolled (only damaged hood, grill and fenders) mainly for the ax-15 to put in my CJ and the tub (probably the straightest ive seen) for my dads cj build. I plan on throwing another body on it and selling it because it is geared and modded for rock crawling. My dad is of the opinion that the automatic (aw4) is desireable among the rock crawlers. Is that the case? would an automatic be desireable? what transmission would yall recommend I put in it? it has a 258 in it. thanks for the help.

Overall manual v. auto is a personal preference, but I think you will find that more serious crawlers will have autos (maybe with reverse manual valve bodies) than manuals. Not having to deal with a third pedal and the benefits of the torque converter at slow speeds can make a real difference. There are people who like to stick with their manuals and most of them will install a hand throttle to try to help with the three pedal problem. Personally, I'm comfortable enough with my manhood that I don't need a manual and when I get in tough situations there is already enough I have to worry about that auto is my choice.

X2 on the automatic recommendation for rock crawling. The vast majority of serious rock crawlers started running automatics years ago.

For your YJ I'd install the 32RH automatic which is what I converted my previous TJ to for rock crawling purposes. That particular transmission is pretty much bulletproof and it runs cooler than the AW4 does. Plus wiring the computer controlled AW4 can be a nightmare compared to the hydraulically operated 32RH.

Not to mention automatics provide 2-3x more low end torque (thanks to the magic of the torque converter) for getting up and over obstacles. True.

I run an AW4 in my '98 and it sees daily driving and a decent share of tough off road. Mr Bransford is correct about the 32RH, but I like the OD of our AW4. With correct axle gearing and multiple trans coolers (2) it does a good job for our needs. There is information available on the net for wiring and needed components. Have fun with the build!

Daily driven, stretched TJ with 108" wheel base.

IME the auto vs stick crowd falls along a few lines of evolutionary devolopment.

1. I'm too macho to drive a girly auto! (Many of these believers can be tracked through the woods by the smell of burnt clutch and the sound of an engine being started every couple minutes). There is a subset of "I like to be 'part' of the driving experience" that can be tracked the same way. It takes further study of the species to discover which branch of evolution the subject has taken.

2. The next group will be devout follower of whichever tranny their father drove. They will also have very strong opinions of the Ford vs Chevy debate. They may challenge you physically or threaten harm to your family if disagreed with. While you may wish to tread lightly in discussions, for the most part they are full of bluff and aren't a viable threat.

3. Those that have actually spent time driving an auto in actual off-road conditions. Gravel trails don't count.

It is a personal choice. There are some skilled folks with a clutch, many more that aren't. If you're doing anything difficult and bouncing around, being smooth on a clutch and smooth on the gas at the same time gets pretty difficult. Bog it and it dies, rev it and there goes traction. Start bouncing and you go back and forth between the 2.

Driving an auto does let you concentrate more on the obstacle and offers a couple mechanical advantages as well. I learned to drive a stick, do ok with it offroad. But I've had more fun exploring a trail with an auto. Just working the clutch pedal isn't that enjoyable to me. I mean I can sit in the driveway and pump the pedal all day, doesn't do much to add to the driving experience IME. I can also fly planes, run boats, atv's, snow machines etc. If it has an engine I can likely do it, although I've not learned to fly a helicopter yet. The clutch isn't used in anything I find to be fun. But ymmv.

I'm the only gay eskimo.

Always been a stick guy myself. Nothing against auto's, the clutch for me is second nature, I dont even think about what im doing, its just natural after all the years

Also I prefer

Pepsi over Coke
Steak over Chicken
Sausage over bacon .... not in place of, but on top of

Learned to drive sticks back in 1964, joined the military and drove all kinds of manual transmissions, and have owned ten plus vehicles with manual transmissions since then. So I have pretty fair experience driving manual transmissions too. Bought my first Wrangler in '96 with a 5-speed manual transmission, thinking that was what was best for offroading too. It wasn't 5 years before I figured out that on significantly tougher trails like for rock crawling that automatics were the better choice. That's when I converted that Wrangler to the 32RH automatic. I never looked back.

What would I want if I was buying a 'Vette, Porsche, Triumph TR-6, GTO, Camaro Z-28? Manual transmission all the way. For my rock crawling Wrangler TJ? Automatic all the way.

Problem solved.

Working with cars is a little like a really awesome date: you start out expecting this to be something simple and straightforward; four hours later you're laying under her, panting and cursing, and things are a lot more complicated than you thought.

That would not eliminate the wiring issue mentioned above.

You can either run on the Rail shifter alone, making the AW4 essentially a manual-shift auto (no TCU needed), or you can toggle the TCU making AW4 an either/or setup. Your choice.

I guess I'm not understanding what wiring issue you're referring to.
