Jk to TJ

Thinking of selling new JK, for older TJ. Actually looking at getting two TJs for the price of one JK. Am I crazy?

While the JK has all the modern convinces, and a bit larger, I kind of miss the more classic lines and simplicity of the TJs. So a brand new JK, with only about 5K miles on it, for a Tj with around between 60-100K miles? Of course, if sold the JK and bought TJ, half the price of the JK left in the pocket.

What concerns should one have on a TJ, 2004-2006 models, regarding the transmission and the I6 Engine, if at around 100K?

Thanks.

Do not get an 05-06 automatic. There are so many problems that are irreparable with that transmission. The 05-06 manuals are better, but many people don't like them because the 6-speed can have some issues and is extremely costly to rebuild. I have an 05 and I love it, but when the time comes it will be more cost effective to swap in a 5-speed than replace my 6-speed. Generally I believe the 5-speed Jeeps are the preferred ones.

Also, if possible wait it out and get yourself an LJ manual (not auto!!!). While I love my TJ I sort of wish (and many others on this forum) that I waited a bit to find an LJ. They have more room in the rear and because of the longer wheelbase they handle the road better. Plus they come with a D44 rear end and a higher towing capacity from the factory. I just saw your location though so that may be an extremely tough thing to find.

Have you thought about adding flat fenders to the front and corners to the rear with the round wheel well? That's what I'm going to be doing.

The OPDA seems to cause problems, or at least I've seen a lot of posts regarding it for those year models. Cheap and easy fix though if you do your own wrenching.

If you don't get an auto you won't get OD. Many 4.0L wranglers I've checked out have an oil leak at the rear main seal, mine included. Again, cheap and easy fix if you do your own wrenching. Unlike the OPDA the slow RMS leak doesn't cause any problems besides a black patch where you park.

The TJ 4.0 has much less power than the new JK 3.6, if you're used to the JK you will notice the difference. It was immediately apparent to me after driving both. So, if you get larger tires you'll need to gear down your axles or the TJ will feel like a sloth.

I you could always spend that extra money on axles, tires, steering, and suspension. Maybe you'll come out even

Good luck in your search

The OPDA is a known issue on the 05-06 models and easy to fix as long as the cam gear isn't chewed up. The RMS leak is a problem with all Jeep TJs. I have a leak but it is slow and doesn't even drip so I haven't went about fixing it.

Absolutely stay away from the 2005 - 2006 no matter what kind of deal you get.. Most are a deal for a reason. The auto tranmisson cannot be fixed. If it is a manual figure a transmisson replacement.

The good years of the TJ is the 2003 and 2004. Also the late 90 models are good but getting very old.

My wife likes my 04 and dislikes the newer models because they do not look like a real jeep.....

Well you're going from a RV to Primitive camp as far as comfort is concerned.

04-06 I'd lean toward 04 for the motor. 05-06 might have OPDA issues, but I wouldn't turn one down.

03 & up went with a 4 speed auto, 05 & up went with a 6 speed manual. Pick your poison. I'd buy either pending on condition & maintenance.

I gave the JK to my wife and nabbed a clean TJ out of Barstow, CA and shipped it to KS. It's like driving a JEEP. I cut my teeth on my CJ2a, and drove a CJ5 daily for years. Always wanted a CJ7 DD but never really had the opportunity. I miss a few things about the JK. But am adding it to the TJ. Such as compass, thermometer, nicer seats, ipod connectivity. But I am enjoying updating the TJ. A little bit of a handful to drive down the highway at 75, but I just slow down a little.

Thanks for all the info. Appreciate it. Did not realize that 03-04s were better than 05-06 models. Good to know.

If you find a great 05 or 06 in manual I wouldn't turn it down. I am not sure how the market is by you but if it is good enough that you can hold out for an 03-04 then I would recommend it.

I was in your exact boat earlier this year!

I had my 2008 JK that had 80k on it with great equity. I needed a truck so I bought my Sierra for my DD and then we traded our Maxima in on a TJ. Couldn't be happier. As said 03-04 are the best for automatics. from '00-'04, the manual was the NV3550. The manufacturer, New Venture Gears, is no longer in business and rebuild kits are very scarce if you can find them at all. Most likely you would have to swap transmissions to an ax-15 or to a beefed up ax-15"terminator" if your transmission went out. Clutches are fine, full rebuilds are not.

The OPDA is a problem, but I personally prefer the NSG370 6speed that was used from '05-'17. It is stronger. Its a give and take if you want a manual. If you want an auto 03-04 is the best for sure.

If I hadn't convinced myself I needed a truck I probably would have purchased a newer JK. The JK is much quieter with the hard top in the winter and a more comfortable highway cruiser/DD. Just my $.02 but if its your DD, stick with the JK

With regards to the '05 and '06 OPDA issue, it is something you will need to get fixed if you have it, but 10 years out odds are the PO already dealt with it. Like any older vehicle, it pays to have it looked at by a mechanic preferably before you buy it, and that is just one of the things to look out for. The '03 and '04 Wranglers are considered the sweet spot because Jeep had worked out all the old kinks before '03 and hadn't yet introduced any new ones, but you can't go wrong with any TJ provided it was well cared for and the frame isn't rusted.

I have a 98 4.0L TJ and a 16 2dr HR. Both black. The JK is an amazing vehicle and is a joy to drive, but I love my TJ much more. It's very heavily modified but nevertheless it's a proper Jeep. IMHO

Any TJ is ok as long as it is not a 05 or 06 automatic. Believe me, I know what I am talking about

I have been driving a 2005 TJ everyday since I bought it brand new. Never had any problems with the OPDA or the transmission.

Not ALL 2005-2006 TJ's have problems.

I have a 99 now that I built years ago . I sold it to a friend and have since bought it back. I also have an 05 Rubicon automatic .It has 4.88s with 33's and have never had a regret. I have no clue what trans problems they have other than to tall of an OD but 4.88s make it a very quick little Jeep. I also had a 2012 Sahara w/AEV lift kit along with many synergy and Currie suspension parts, 35"KO2's. It was more powerful than the TJs but much less fun to own. I prefer to own the TJs . TJ's are much more fun to work on and a wider variety of parts available.TJ section of the forums seem to have more experienced members and more in depth threads. The JK forums seems more like an advertisement for the last manufacture who stroked a few of the members. TJs are more like what a jeep has always been.

Congratulations on you finally getting a Jeep. Don't assume the TJ will be much cheaper than the JK you sell.

BSA, where are you getting your information ? I know many who have had virtually no problem with with the manual transmission in the 05 and 06's. Thousands of them were sold. Yes OPDA was a spill that you need to watch out for (low probability) with a known fix. If they are so bad, why do the 05 and 06's go for so much money ????

I second this. Bought mine brand new in 2005 and still daily it. Besides regular maintenance and my fan clutch going out I haven't had any issues with anything else on it.

My first 97 TJ had over 200,000 miles with the I-6 and it drove without any issues until it got totaled. My 2000 TJ has 136,000 miles with the I-6. I definitely think you would enjoy a TJ, but as others have mentioned, stay away from later TJs if possible.

Its the 2005 and 2006 automatics that are the problem ones. You're right that not all 2005 and 2006 automatics have had issues, but there are plenty around that do have the issue and there is really no way to fix it without a ton of money. That is why it is recommended to steer clear of the 2005 and 2006 automatics. The manuals for those years are a bit better, but many people don't like them either because the parts to rebuild the transmission are either really expensive or impossible to get. I have a manual 2005 and I love it though. When the time comes to rebuild I will probably swap in a 5-speed due to cost though.

BSA, where are you getting your information ?

The problems with the 05 and 06 automatics. Just google, this is a well documented problem. I would not have a problem with those years in the manual. Just keep in mind, if there is a problem with the manual, it will be replaced..

I know many who have had virtually no problem with with the manual transmission in the 05 and 06's. Thousands of them were sold. Yes OPDA was a spill that you need to watch out for (low probability) with a known fix.

IMO the opda is a non issue. It can be replaced for $100.

If they are so bad, why do the 05 and 06's go for so much money ????

Many people never research what they are buying and only find the problem before it is too late....

My issue was lumping the manual in with the automatic. I would never recommend the automatic but that's a topic for another day. Yes the 6 speed is expensive to replace, but I am unaware of many who have had to do so and properly maintained it should outlast the frame. Those, by the way are even more expensive to replace.

Issues with manual typically can be traced back to improper body lifts where no correction was done to the shift lever interference. Incomplete gear engagement ends up wrecking the dog clutches inside the transmission.

We have to remember that most never comment on this forum when their vehicles operate properly, so we should not assume the level of comments on this forum regarding issues are representative of average reliability.
