An auto gives you huge control over your traction in the rocks which to me is the primary advantage of having one. The fact thay will shift for you when you want them to is a nice bonus for when you are dune/desert running. |

Ya know; i've never actually watched someone's feet while driving their autos. Maybe I don't have a fetish afterall.
Seriously; I never knew you guys drove with two feet. Believe me; I wish I had an auto at times. Then again; i'm with blkTJ. I like my manual and would like it even moreso with gear reduction. I really don't have the need for high speed desert runs or dunes for that matter.

Mine tachs out pretty good on 35's with 4:56's at 75 plus but its fine over the road for me because I don't drive that fast (unless I have to pass) so you won't have a problem on 37's with 4:88's in the diffs.

But seriously, you do drive with both feet. It takes a little getting use to......you hold the engine RPM at one point and then simply modulate your forward progress with the brake pedal. If you find that you are not making foward progress with the brake fully released, you apply brake pressure again and then add a few hundred more RPM to the engine with the gas pedal......now slowly release brake pedal pressure to control your forward motion....adding more or less brake pedal as necessary for you to crawl the desire line. Using this technique you can reduce your forward travel to inches per minute, if need be.....without ever actually stopping the vehicle. Once nice benefit is that when you decide to stop, you don't get that huge driveline unloading like you do when pushing in the clutch. Until you try it, you really can't appreciate it.....just like so many other worthwhile Jeep mods. |

Eric, Try the 4:1 first. You can hook'em up for like 750 online. I think you will like the difference in crawl ratio even with your manual. If not then look at doing the AW-4 swap. Stu can help you with that one. And if i'm not mistaken didn't you blow a front passenger U-Joint and Shaft the first run out with your 37's on the rock garden at Payette Draw about a year or so ago? |

Yes; that was a stock shaft and u-joint. I've been on chromolly's ever since and just broke last trip there. Not bad odds for my setup.

I've decided to either run a 4:1 or a Rubi TC. Now I want to look into a cleaner underbelly. High pinions would be ideal, but I can't swing it at this time.

I did have to fab up a transmisison mount and an exhaust hanger. No big deal with either one. The CPS required me to unplug the sensor from the harness and plug in one from a '00 as the '03 unit uses 2 bolts to mount it on the bellhousing and the '00 model used one bolt (be sure you space it off the flexplate correctly...too close and you could ruin the CPS, too far away the engine won't fire). I had to figure out the wiring for the backup light plug so they would come on when I stuck it in reverse...not a big deal with a test light. The auto was about 1.5" shorter than my manual so I had to lengthen my rear driveshaft. Lastly, I had to modify the t-case shifter linkage (lengthen) to allow proper t-case shifting, and I did have to fab up a transmission tunnel cover to work with the '00 style shifter setup. While all these mods can sound daunting, don't let it keep you from the swap. I did this swap by myself, in my garage, in a couple days (IIRC). This included modifying the RE belly skid and raising it up to mimic the drop of the older TJ models (about 1.5" below the frame). While I'm not the metal worker or fab guru some others are, I'm pretty pleased with the outcome. And I absolutely love the auto in the rocks. Quote:

However.....I was under the impression that the PCM was responsible for locking up the torque converter on the 32RH. Am I wrong about that detail? If I'm not, how did you get the manual PCM to control the lockup solenoid? |

That would be awesome!!!!!! You could even do the tranny swap in Fred's shop. I'd like to do it soon as wheeling without a 4:1 is taking it's toll on my tub. I can wait though. Just give me an idea when. Heck; i'd drive down and help you with the swap if you'd like. It would be interesting to see. I've got a whole 20,000 miles on my TC. I heard from a Tera dealer today that there has been problems with Tera Lows in the past. One was the spitting of fluid from the vent and the other was incorrect cutting of the planetary gears causing loud operation. Anyone want to clarify this?

I haven't had any issues with this Tera Low spitting fluid. It is noisier than the stock 'case, especially when you hit 4th gear in low range, but I haven't had the opportunity to compare it to other Tera Low 'cases to see if it's better or worse than the newer versions. Noise in 2-high is minimal, but you can hear it at low speeds.

We just used a toggle switch to lock the converter when we swapped Fred's, and I'll probably do the same.
I'll have to see if Fred still has his list of parts so we can start the search.

Dan, I knew that the switch option was available but for me, I would not be happy flipping a switch. My rig sees a lot of city driving as its my main transporation on my normal 3 day off work schedule.
Doesn't the torque converter generate extra heat when it is not locked up? I thought I remember Fred saying bad things about running it down the highway without it being locked. Fred? |

Teralows'
.........can be noisy and some of them do spit fluid out of the vent. Running a good synthetic ATF helps to cut down on the noise in my experience and I have never had the venting problem - at least not with the case I have in the Jeep now. The first case I had blew a$$ and was replaced. Stu knows the story on that one Eric. The second case has been very good to me and has never given me any trouble.

Maybe my question should have been....."What problems, if any, will a lock up torque converter incur if it is always operated in the unlocked mode?" |

I have an old style TH400 3 speed auto in my Suburban. It has no lock-up. I've added a deep pan, auxilliary filter and a cooler to it. It will run up to 220 towing my Jeep up the Cajon Pass but thats the hottest it gets. Just by itself with no trailer or Jeep, it runs about 160-175.
Dunno the about the effects of no lock up on the Jeep 3 speed but given that its a decendent of the old torqueflites, I think they are pretty durable so the lock-up switch and having to hand actuate it would probably be of little impact. |
