Tranny shifts seem a good bit smoother, you hear them thru the change in engine rpm rather than feel them in the seat of your pants now. A side note, they've discovered that the tranny dipstick can be tricky to read unless you closely follow the instructions, mine turned out to be 2 quarts low even after being checked at normal service 4 weeks ago.
Engine is noticeably quieter, especially at cold startup idle. Acceleration from a stop is quicker with the same amount of throttle. Throtle seems more responsive and engine spools up to power quicker.
Drove it 70 miles yesterday, and so far no noticeable effect on fuel economy, at least I didn't notice any decrease.

Cool pictures!
I have talked with two diffrent sales people at the local jeep dealer and two diffrent pieces of information about the engine. One told me the engine is the same engine Volkswagen uses; the other told me it was a Mercedes Benz. I called the dealer to complain about his web site and gave him heck about the poor and incorrect info the sales staff was giving.
May have fallen on deaf ears, I don't know, but if Im told BS again I'll write Chrysler and complain.
I think the 2.5L CRD came out in 2001. I met a few people who had Jeeps with this engine, and they never said it was more powerful than others. I strongly believe the automatic transmission makes the difference.
I have BFG A/T 225*75*16 on now. They lost their agressivity on ice+snow due to wear (their 2nd winter season) but in soggy soil they dive about 5 inches and pull like in a cog-way. I just prayed my Spanset could support the effort and it did. When the work was finished we all laughed because the trees were enormous compared to the Jeep. I'd be curious to see how this type of work could be done with a 3.7L gasser

Best of luck with it...LK :confuse:
I haven't had any service done other than an oil change. The tranny shudder usually occurs after a down shift acceleration and then shifts back to 5th. It's tough to tell if it's really the tranny or the engine.
I had been getting 23-26 mpg on the highway doing 75-80 and only recently had two consecutive in-town tanks that produced 20.5 and 21 mpg. The in-town didn't surprise me as each tank consisted of very short trips to the kids school and back. This recent trip to Colorado resulted in lower mileage than I expected. I did have four people and our ski gear plus the ski rack on top. Best mileage for the trip was 25 mpg, worst was 21.5 (this included about 175 miles of in-town driving.
I've used Powerservce but have seen no improvement in mileage but rather a decrease if anything.
I'm setting up a service this week. I'll post back with results.

Sale Price $20556
Difference $7764
Willing to take over $7700 off the top makes me wonder what might be wrong with this car. I like the price, but keep looking for the strings that might be attached.
CarMax is very aggressive on their pricing of new vehicles.
Have fun!! LK
Oh I see why.
Isn't there a decent mechanic at a corner gas station/service center ,nearby that could do the job ?
Just trying to save you some $$'s .
Speak Soon

This way you have access to the service Tech's that are trained on her,if there is a serious problem.
Thats sounds like an awesome deal to me.
Speak Soon.

I experienced something similar before I removed the egr out of the way. When from idle speed (in neutral of course) I accelerated briefly several times, the engine studdered and finally stopped. Something choked it. This should have never occured on a diesel. The diagnostic was simple and has proven to be reliable for several weeks. Later this spring I will repair the egr valve because it worked well when it was new.
Another detail concerns the specific metallic sound of the engine when the mixture is lean. The egr valve is normally open when there is no load on the warm engine, and the sound changes. What I called the "happy woodpecker sound" in a previous post I only had since the valve was disconnected. When the egr works well, we are never in a condition of lean mixture because the valve reduces the oxygen going into the engine.
Call in a musician, she/he will tell the difference
CarMax also sells new Nissan, Toyota, Scion, and Chevrolet in a few areas around the US.
CarMax is an excellent online price reference when buying a brand that they sell new. I've saved significant $ over the years by using the CarMax pricing to negotiate with local dealers.
A friend of mine (and no it's not me because I'm the furthest thing from a mechanic) worked for a tire and service center. It is a well known tire center in the NJ area. I had the privlidge of hanging in the shop on many occasions while they performed oil changes, tire rotations, etc. As someone mentioned, this junior mechanic as he was just out of ASE school hated to do the oil change because they made no money on them. They would burn their hands, get dirty and get little reward for a quick change. On many occasions, the customers who were complainers or thought they knew something about cars were rewarded with metal shavings from the brake lathe in their freshly changed oil. Just some thought for the next time you give your keys to someone at one of these establishments. This is why I have always changed my own oil no matter how good a certain "special" may be.

I think buy in Orlando or Atlanta, one way ticket east and a road trip home. :shades: Might be fun as I have never been to the right side, or is it the Other side. :P
Keep trying.
We're having to foot the bill at this point for flushing out the intake system (not covered under warranty) and for the throttle body (a $650 part!!!). Double ouch
This I copied from another forum...It really scares me.
NOT COVERED UNDER WARRANTY ????
:confuse: LK
I read over 20 different diesel blogs and technical papers while searching for the words “black smoke” and reading just those sections. It turns out there is one common thread:
Excess Fuel=Not Enough Air=Black Smoke.
When you punch the “throttle” on the CRD, the injectors dump fuel creating an over-rich mixture creating lots of black smoke. The turbo spools up quickly providing plenty of air and the black smoke goes away.
Some vehicles do this less than others. The Jetta TDI dumps fuel with a 0.25 second cutback by the computer. The fuel is already cutting back in anticipation of the sudden turbo boost emitting a small puff of black smoke.
I get the impression that the CRD engine gives us all it can. When you punch the CRD you get an almost immediate 23 pounds of boost from the turbo at 1800 rpm – after fuel is dumped and a slight lag, of course.
If someone wants to make the argument accumulated oil is blown out of the intercooler hoses into the intake contributing to the black smoke that could be true. I found nothing on that.

I purchased a 2005 Jeep Liberty Diesel in Michigan. My overall experience has been nothing but TROUBLE! And, these troubles have been compounded by a rather apethetic dealer and DCX customer support team. I have had an ongoing RATTLE with the exhaust they cannot fix. I have had 2 airleaks, replaced EGR, two power losses (unexplained to me by dealership as typical NPFs), muffler replaced, exhaust removed and re-installed, RATTLES Again in Exhaust, and continual POOR Alignment.
I have sacrificed 7 work days
12 days out of service
Received rude comments from both DCX and Dealership
AND I STILL HAVE MY PROBLEMS WITH ZERO, ZILCH, NADA RESOLVE. I AM GOING TO EITHER BUYOUT THE LEASE OR POST ON LEASESWAP. THEN I AM GOING RIGHT TO THE TOYOTA DEALERSHIP AND BUYING A CAR FROM SOMEONE WHO CARES. MY OWNERSHIP EXPERIENCE HAS BEEN NOTHING BUT A DISASTER!!!! :mad: :lemon:
I'm experiencing similar problems with my new '06. Took delivery of it last month and on the drive home from the dealer, the stuttering started with only 150 miles on it. It's been doing it ever since between 17-2100 rpm's with OD off which is 40-50 mph. And now also about 55 mph with OD on (around 17-1800 rpm's). We live at 9000', and commute to town at 5350'. Only happens when we're holding speed or slightly accelerating, hot or cold.
We've tried: checked that all hoses were tight, different fuels, cetane booster. We always warm up for at least a good five minutes before moving, and usually have the engine block heater plugged in for the night. Nothing has helped.
So finally took it to the service dept. last week. They said there was a TSB fix for it. After they programmed for it they said it works fine, but once I left for home and hit 50mph it started again. [TSB# = 18-038-05]. It's now back at the dealer waiting for a torque converter, that STAR says will fix it. We'll see. :confuse: A shame I can't drive in the sweet spot for best MPG without the stutter/shudder/hesitation/jerking!

Sales of the Jeep Liberty CRD diesel are about to surpass the 10,000 mark, double the number expected when Chrysler Group launched the Jeep Liberty CRD diesel in early 2005.
Sorry about not getting back to everyone. Computers and I don't spend much time together.
Drove to the big city a few weeks ago and spontaneously launched off the highway at 65. Haven't left the road in 29 years. After 70 miles of dry roads in 2wd I noticed myself steering into a skid and thought, "That's funny... I'm dreaming about driving; I should wake up soon.". Then it hooked up and launched me off the road sideways at 65. The snow was perfect. I didn't wake up cause I wasn't sleeping. Watched the merge sign travel across the windshield from right to left and forgot to signal. Travelled up a steepish embankment to the entrance ramp; still sideways and launched completely over the entrance ramp road (steering wheel does nothing when airborn) and landed sideways in the ditch on the other side stopping 3 feet from a huge concrete retaining wall; still sideways. Put it in 4wd and got out to see if I'd hit the wall. Looked across the ramp for skid marks and saw two plumes of snow across the road where my wheels (plows) had thrown it. Looked pretty stuck... up to the hubs on the left and above the tires on the right. Stomped the snow behind it and backed up a bit; stomped the snow in front a bit and drove right out. Didn't want to stay long because I figured someone else was going to want my parking spot. Not a scrach on the jeep or me.
The cause was a shadowed area under a diagonal overpass on an uphill right-hand curve that had kept its' ice. Torque, hill, and diagonal ice combined to aim me and the trac-loc worked well to launch me. Just luck it didn't flip or hit someone on the ramp. It's a known trap that got written up in the paper years ago. That's twice I've gotten out of this thing thinking it's wrecked. Odd feeling... usually they are wrecked and that's a very rare event in my life.
All a powerfull argument for traction control and slamming on the abs whenever in the slightest dreamlike state. I still like my trac-loc. For grunt work it's a better machine. It would be nice to have traction control and limited slip but I can see the engineering conflicts there.
I can't blame the car, road, or anyone else. Cheap lesson for me. I have to say this happened sober and sane before I watched any of the Olympics or read about the right hand rule. Gotta go... I've posted too long.

Even though higher cetane gives smoother combustion, I found that LSD and ULSD never gave me good mileage compared to 350 ppm sulfur diesel fuel.
