It's a unique situation -- I have a 2012 JKU and want an LJ. I'm most likely trading with someone and he's paying off my loan + some cash. The LJ is built very similar to my JK, even a little more built. It does already have a hand throttle, so might help me a little in the meantime.

I would definitely contact Blaine when/if the time comes.

suicideking I'm most likely going to get a 2006 LJ with 6 speed manual. It's not a Rubi, but has the NP241 tcase.

What would the rough cost be to change to auto?

That's a good way to do it, I didn't have that option when I did my conversion.

Your only issue if you swap PCM (ECU) then you may want to swap inst clusters and odometer readings will probably swap with PCM

Last issue is the sentry key issue if one or other had a sentry key you have a big issue as if a PCM is plugged into a TJ with a sentry key reader in the ignition key that PCM will have the sentry key function permanently activated and never again be useable with out using a sentry key even if you plug it into a TJ that does not have that feature

Jerry Bransford In that scenario all I can think of would be an extended output shaft seal for the 32RH going into the TJ that used to run the AX15, a new clutch and throw out bearing, and fresh ATF+4.
05-29-2014 01:15 AM
blade4804 So also a scenario here. 2 x 1999 TJ Sports 4.0, one is an auto one is a manual. Side by side. Can you just swap part for part? Or do you still have to buy stuff?

Thanks
05-23-2014 10:39 AM
Jerry Bransford There are changes, like the 32RH output shaft seal needs to be extended when bolting it to a 231 that had been bolted to an AX-15. Plus the front driveshaft needs to be swapped for one made for an automatic to clear the wider transmission pan of the automatic. Rear driveshaft length needs to be changed too if I recall correctly, it's been too long since I did mine.

Mike02TJ With this Change in a earlier TJ (97-02) going to the 34RH out of a TJ, Will the Transfercase, And stock Drive shafts still work with the New Auto Tranny?

1998 Jeep Wrangler Automatic to Manual Transmission

HEY LIVERMORE MIKE

It is my first time here and apologize bumping in.
I have a 1998 Jeep Wrangler 4.0 L sport with Automatic Transmission.
I am considering maybe swapping my Jeep with your 1998 Jeep with Manual Transmission.
Let me know if you consider it.

That sounds like a ton of work and money . With CPUs and sensors + equipment. Your better off just teaching her how to drive it. And have peace of mind she can drive anything on wheels and let her get some cool points for being a girl who knows how to drive stick

Oh- I didn't know if there was a difference .. You're welcome to it if you can use it as a trade , or conversion , or whatever you can use it for ?? I'm in S.C.

lindel I'm not positive, but I think the 88 came with the TF904, or the TF999. No computer controls that I know of, but no lockup either.
02-25-2014 10:22 AM
Jerry Bransford The easiest would be a 32RH automatic, which I did a conversion to in my TJ years ago, that was used back then but you'd have to get more advice about your earlier YJ. Your '88 didn't come with a computer that could control the lockup torque converter that is in later model 32RH autos. That may mean, I don't know for sure, that you may have to get an early 32RH without the lockup torque converter. I'm really only totally up on that conversion process with '97 or newer TJs.

I'm a huge fan of automatics but as I did with my then 16 year old daughter (now over 30), I would just teach her how to drive that stick shift. It took her a couple hours to learn with me sitting next to her but that's a lot easier than converting to an automatic.

I did my 99 2.5 but I went from auto to manual. This is what I had to switch. Floor shifter. Floor tunnel cover(what the shifter bolts too) Had to remove the trans cooler lines in your case add them. Interlock cable from the shifter to the ignition not required unless you don't want to shift into gear with the key off. The shifter itself shifter cable. Transmission transfer case. I used a different drive line because my setup came out of a yj should be the same for you. Trans mount plate for me but yours should bolt to straight to the trans. Flywheel different length bolts that hold the transmission to the engine and a computer out of an auto. And a petal set unless you want to confuse anybody driving it also kick down cable. This should be every thing you need. It took me Two days to do the swap but about two months to source the parts. But I did it all for about 800. But I practically lived on craigslist to get the good deals first. I used most of the hard parts from a yj the petal set and "wearable" parts had to come out of a tj. That for a 4 banger though hope this helps you.

I have a Auto Trans from a 04 Rubicon coming to me next week, I will have everything from the block back, no linkage, no computer...but I can get in touch with the shop that has the jeep to see if they still have those parts
08-15-2013 10:05 PM
Jerry Bransford Yep it's possible, you'll just need a new PCM, Transmission Computer, PCM to Transmission Computer cable, and the mechanical parts.... transmission mount, shifter & cable, flex-plate to replace the flywheel, etc.

It's a major undertaking but I did it to my '97 & it worked out well. But with a newer TJ like yours which is a bit more complex than my '97 was, I'd seriously consider selling it & buying one with an automatic already installed.

Is the swap for the 2001 4.0L the same as for the 2000? I know that I have the nv3550 tranny now and will be swapping to the 32rh. It definitely seems from the reading that I have done so far that the conversion is around $1000 for all the parts and such...

I've had my eye out for an automatic 4.0 but I haven't seen anything that compares to mine. My Wrangler is a 2001 with only 61,000 miles on it, all the automatic's around have 120,xxx + and are listed in the 6k + range.

Any chance you still looking for a 2005 Stick shift tranny with 83,000 miles to swap with an automatic ?? Thanks

JoeyEsp Hi, i was wondering if it would be possible to convert my 09 wrangler from manual to automatic. what would i need to purchase inorder to actually accomplish this?
01-14-2011 08:21 AM
jmaldonado I just bought a 2000 Wrangler TJ that was converted from manual to automatic. It runs good but I have one little concern: Often I see the little arrow light, (the one that tells you it is time to shift on manual transmissions) on the dashboard come on, and the jeep starts jumping a little like looking for that next gear. Is this normal or could it be that whoever made the change forgot to change the computer or installed the wrong one.

Thank you for your input in advanced,

Julio
10-27-2010 12:20 AM
Jerry Bransford The only way you're gonna get rid of those codes is to replace the present PCM (aka ECM on older vehicles) programmed for an automatic for another PCM programmed for a manual transmission. As it is now, the PCM is looking for sensor input signals and codes from the auto tranny's computer and it's not gonna get them from the new 6-speed manual transmission. You can find replacement (rebuilt) PCMs on eBay.

04 wrangler auto to 05 manual 6 speed

I'm helping a buddy who converted an automatic 04 wrangler to a 6 speed from a 05. he has several codes p0706 shifter signal, p0750 lr solenoid circuit, p0846 2-4 pressure switch ,p0871od pressure switch, p1899 park/nuetral switch. any idea on how to get rid of them? maybe replace the ecm, or fake the sensors?
thanks for any help
08-22-2010 04:57 PM
robbytwo1 I have a manual tranny and think my computer went bad... do any of you that made the switch to an auto transmission still have the computer you took out of your Jeep when it was set up as a manual? If so please let me know. I am interested in buying the computer. I have a 2001 4.0 Wrangler. My cell is 407-770-8281. Robert.
08-06-2010 02:07 PM
KBR97 Can the donor vehicle be a XJ by any chance? If so I would be able to use a lot of stuff like the transmission, computer, and the high pinion D30.

Is this true? Mine is a 2003 and i would like to swap it over, is there any other way to get it done?
Thread revival....anywho. Its really not worthwhile, you'll have better luck finding a different jeep.
