CSM41 I have built 5 Jeeps in the last 20 years and five of them were manual transmission Jeeps and I loved them all...now I have a 1999 TJ with a 32RH auto and it is by far my favorite. I never knew what I was missing all these years. No, I'm not running anything overly fancy either; Lift, 35 inch tires, Detroit lockers front and rear. It just works well. In everything.

LucaBrasi Thanks for the info. The TJ I am looking at is over 115k for miles! I'll have to pay attention to how it shifts.

Sorry to thread hi-jack

Jerry Bransford I don't believe the WJs used the same transmission but I guess it's possible if the WJ had the 4.0L engine. The 4-speed automatic's reputation is not as renowned as the 3-speed's is. That isn't to say it's failure-prone, mine has over 87K miles on it, but people just aren't as happy with it... especially due to its extra-steep overdrive ratio that makes extra-low axle gearing the way to go.

Oh that is unfortunate (I must have misread elsewhere). How's the reputation on the 4-speed?? I hope it's not the same thing that crapped out in all the WJ's from that time...

Sorry n00b question: Are all the 3-speeds this tranny you are mentioning? I am looking at a '01 sport 4.0 auto this weekend... Will it def have that one in it?

I should have it packaged and ready by end of the week.

jlong21 Im new to wrangler forum, started surfing posts, ran across this one, and had to reply.

Im in the middle of an auto to manual swap myself (swapping nv3550 from an 03 tj to my 97 sahara). I've got my auto tranny off, installed the clutch pedal, master/slave, flywheel, pilot bushing, pilot bearing, and clutch. I'll be bolting the nv3550 on tomorrow, then measuring for driveshafts, and should be finished!!!

If you have any questions regarding the swap, let me know and ill do my best to answer.

My '98 Sport is a 5-speed, and that's the only thing I don't like about it. My two former 4.0L TJs were both automatics, and it makes a world of difference out on the rocks. I could easily see myself converting this Jeep to an automatic....

Oh sure it is, we have 580hp small blocks that crawl just fine on the doublelow side. I overpower everything because I want it there when I need it I dont call 30 mph crawling, but thats the only way anyone can make it up those trails I guarantee it.

NHWRANGLER im not bashing autos jerry. well not intentionally. in fact i found myself yesterday wiching i had an auto when i smoked my clutch in the woods. poured smoke. whoops. but i lovemy 5 speed. theres no real rock crawling here in nh like there is out there. most ppl just go trail riding on old horse and buggy trails and logging trails. and mud. i agree completely with putting an autoin a rock crawler.
08-17-2011 06:27 PM
Jersey Sahara I have a stick in my jeep and it's my first car. I'm only 17 and I love wheeling with the manual I don't ever plan on using anything but a stick I love it
08-17-2011 05:44 PM
Lando25 Im also looking into this as well. I don't do a lot of off roading because my TJ is my daily driver. IMO a stick is always more fun to drive than an automatic regardless of what your driving
08-17-2011 05:44 PM
Jeep_VT I wish I had a manual......I don't much like my auto. I don't do any crawling really, and for just offroading, i feel like I would be fine. Sadly, it appears as though it's out of my budget.

But for a Jeep that sees really tough or extreme level trails, an automatic actually helps it perform better. Not to mention the little-known fact that the torque converter used in all automatic transmissions gives 2-3X greater low-end torque which can make the difference in getting up an obstacle or not getting up an obstacle. For most off road trails, it doesn't really matter but the tougher the trail, the more an automatic transmission makes sense.
I hear ya bud, I completely understand where and how an auto can be beneficial. If I did the type of wheeling you do, I'd consider one too. For the way I drive, a manual is exponentially more fun, and it's probably where the original poster is coming from too. It's cool that they made both auto and manual in these things. I know if I ever wanted to go from an auto to manual, I'd probably just sell and then buy... granted I didn't have a lot of work into the auto Jeep

InvertChaos Let the man do the swap. Its his Jeep not anyone else's. IMO it almost adds to the challenge. Where is the fun in the trail if you can just roll up and over every rock? You might as well be driving down the interstate sipping your Starbucks. I don't hold opinions about people on their transmission choices (that's just dumb) and I can see how in a competition setting it can give you an edge, but for fun? It really is personal preference. Like he said its his DD and wants the extra mileage (its negligible however). I personally love my 5 speed, however I would like cruise control.

For the record, all three of these rigs were manual and running the comp courses at Rausch (I'm sure its nothing compared to out west) without breaking a sweat.

My previous (stolen) '97 TJ came with a 5-speed manual transmission and it had f/r lockers together with 4.88 gearing and 35" tires. I had to winch it up the same three rock crawling obstacles (dry waterfalls) on a trail I did nearly every year. No way no how could it make it up no matter what line I tried. Few others could make it up those waterfalls either. Then I converted that TJ to an automatic, with no other changes, and it then easily made each of those three rock waterfalls with no winch needed. The only change was converting from the 5-speed to the automatic.

That 2-3X greater low-end torque from an automatic is no jive.

jameslee97206 My jeep was converted from an auto to a manual by the previous owner. I have receipts, he spent around 4 grand. I think he got ripped through.

I guess all the pro-level rock crawlers are "sackless" then. Go to something crazy like the King of the Hammers combination race/rock crawl event in Johnson Valley and see how many are running automatics. In fact, the vast majority are running automatics. The King of the Hammers race/rockcrawl vehicle I had a small part building had an automatic (AW4) transmission.

NHWRANGLER autos are sackless in my opinion. dont mean to get anyone fired up. but manuals are fine off road for 90% of jeepers who just wanna have a little fun in the woods and mud. just put in a hand throttle

Jerry Bransford Not sure what year TJ you have but so long as it is a 2002 or older, the wiring harness for the AX-15 is already there. For a 2003 or newer, it'd be a bit more difficult to install as you'd have to do some wiring/connector modifications.

And to me, as one who converted his 5-speed to an automatic for rock crawling purposes, converting from an automatic to a manual transmission is a giant step backwards. Go to any extreme pro-level rock crawling competition and you'll find it very hard, if not impossible, to find any transmission but an automatic. Most experienced offroaders who do the toughest trails convert to automatics, not the other way around.
