It's green diesel engineering, I believe it was $450 to re-program the computer. They have 2 (or 3) programs for it. One, the ECO tune is for Liberties that have the stock Torque Converters. Then later IF you want to create a real Beast, they have the HOT Tune (a $50 upgrade), for those who have rebuilt their transmission and gone with a Heavy Duty Torque converter.
It seems that most stock transmissions in Diesels just cannot handle the power of engine upgrades. I am currently rebuilding the transmission in my 92 Dodge Ram 250 with a Cummins 5.9L, they seem to last about 150k to 180k from normal use before the transmissions start slipping, and if (as most have done) you have made engine up-grades, the stock transmission cannot handle the power. I bought my 92 Dodge new and intend to keep it for life, so I am putting close to $4k into the transmission to make it Bullet proof and able to pull 40 foot trailers with no porblems.
Within a year I will most likely do the same to my Liberty CRD, since I plan to keep it for many years and will useit to tow my boat and quad trailer.
On the CRD, I feel the most important up-grade is a Provent system ($200, or many have made their own for under $20). this removes most of the oily sludge that the smog control system forces back into your Turbo and causes expensive repairs.
The CRD is not a car for a person who just wants a turn key vehicle out the gate. But IF you are willing to do some research and make the recommended changes to bring it back to how it was designed to be in the first place it is a mini beast, and can easily go 300,000 miles. It is a German designed Itallian diesel that was butchered to cut production costs and meet USA smog requirements. There is nothing in it's weight class that can match it's towing abilities. In Europe it is rated at 7,000#'s towing capacity.
It gets better MPG than any similiar vehicle. It turns so well it can almost run into it's own rear end! It is rare and will hold it's value better than gasoline Liberties. Those that are not loved will be disappearing and those that remain will increase in value due to supply and demand.

Winter2 is occasionally posting over in the Outback discussions. Maybe he'll see this thread.
Or maybe part of a settlement with Chrysler was not to say anything.

Me too. Curious about winter2 and wonder if farout is still checking in. My guess based on silence, even though he was fighting mad and burned by dealership(s), that he may finally have taken the hit. Caribou keeps chiming in with how great his 2.5 Euro spec diesel is but his dealership service payments, if memory serves me well, were substantial. True cost of ownership is horrific. Desmog the engine out of federal law, buy a suncoast torque converter, buy the Green tuner, buy good ball joints, hope the motor does go south for the heck of it like Darby and Winter. The list is endless. Penske GM Daimler/Chrysler who else owned or owns VM and who cares. For some the diesel is dead but some writers keep insisting the diesel hybrid is the next solution for the auto world. Some say the last gasp like the horse and buggy in 1890.
One of my mags mentioned that the 3.0 VM Panther engine better be a success for the jeep grand cherokee or kiss Fiat Jeep diesels good bye.

Thanks. Knew about the Mercury but the Subaru is news to me. Guess we know now. Guessing he got the H6 and turbo. Need to go find winter2.
Mercury is gone and he had a Liberty. Now he has a Subaru Outback Premium 2.5. Good Luck winter2.

Good point, never thought of that. Except that if they did the right thing in the end I would think they would want him to tell the rest of the saga in some futile attempt for them to redeem themselves. Poor guy, no matter what they ended up doing, even if he got a new engine (one that they emissioned to last) he still has a pile of patience. Tons more than I could have mustered.

The (central) stator coupled to the 45RFE was incriminated on the higher Torque / HP engines.
My engine is a de-rated 2.8L producing only 150HP , but flawlessly during the past 10 years.
I live in the Alps (in France) where temperatures vary between -20°C and +35°C at 450mt altitude. When we ski we have -25°C at night; I only check my antifreeze (-37°C) and sufficient tire pressure.
My shortest drive with the Jeep is 20 miles, I prefer to use my vintage Corolla 2.0D for short trips and city driving.

Hi tired old dave,
My engine came from the very first batch to equip the Jeep 2.8L CRD; it had been successfully tested on the Alfa Romeo Giulia.
My dealership had a wonderful head technician in 2003, but promotion moved him to Mercedes Benz vehicles. They've not seen me since the ball joint recall that wasn't needed for my truck because it already had the PTFE lining.
Radio silence since then ...

Thanks for the 2.8 correction. I would've lost any bet but I seem to remember the 2.5 was the forerunner for the 2.8 and your model. Americans got an inferior torque converter (weaker springs) for years before they got the Euro spec. I believe winter2 was in communication with VM about that and oil specified by Daimler/Chrysler. Obviously with a new Euro spec KJ (Good initial quality control) and your ambient temperatures, you have been served well.
I still think you should've made Post #10,000.
Good day and no need for me to check in here anymore.

I don't have a heated garage. Everything on this jeep is difficult to do. It was not built to be worked on. I've had it for almost 8 years now. What do you folks recommend as a rugged higher mileage vehicle? My brother has a front wheel drive Ford Escape and loves it. the traction is better than this stupid rear wheel drive Jeep. As soon as times get better for me, the Jeep is going to be history. The dealer tells me that there are only two of these in town. If I have them do any work, they have almost as steep a learning curve as me.

try it in 4 wheel drive, if you still have trouble your tires are wrong for the snow.
It's not any harder to work on than any of todays vehicles with smog crap engulfing the motor.
If you have had it for 8 years, your garage cannot be cold 12 months out of each year?
What are your other specific complaints, we may be able to point you in the right direction.
