WInter2 - Thanks for your support.
I got the text from LOST. I probably had this done too:
Here is the text:
CUSTOMER SATISFACTION NOTIFICATION F37
REPLACE TORQUE CONVERTER AND REPROGRAM THE ECM AND TCM
Customer satisfaction is very important to DaimlerChrysler. Accordingly, we are recommending the following service on some 2005 and 2006 model year Jeep® Liberty vehicles equipped with a 2.8l diesel engine and an automatic transmission.
The problem is...
The transmission torque converter on your vehicle (VIN: xxxxxxxxxxxxxxxxx) may fail. This can cause a rattling sound in the neutral or park positions and/or illuminate the Malfunction Indicator Lamp. Continued operation can result in transmission damage.
What your dealer will do...
DaimlerChrysler will repair your vehicle free of charge (parts and labor). To do this, your dealer will replace the torque converter and reprogram the engine and transmission control modules. The repair involves a small reduction in engine torque to enhance torque converter and transmission durability. The work will take about 5˝ hours to complete. If testing indicates the transmission has been damaged, another hour will be required. However, additional time may be necessary depending on how dealer appointments are scheduled and processed.
What you must do...
Simply contact your dealer right away to schedule a service appointment. Ask the dealer to hold the part for your vehicle or to order it before your appointment. Remember to bring this letter with you to your dealer.
If you need help...
If you have questions or concerns which your dealer is unable to resolve, please contact DaimlerChrysler at 1-800-853-1403.
Please help us update our records, by filling out the attached prepaid postcard, if any of the conditions listed on the card apply to you or your vehicle.
If you have already experienced this problem and have paid to have it repaired, you may send your original receipts and/or other adequate proof of payment to the following address for reimbursement: DaimlerChrysler P.O. Box 4639 Oak Ridge, TN 37831, Attention: Reimbursement.
We're sorry for any inconvenience, but we believe that this service will help to ensure your continuing satisfaction with your vehicle. Thank you for your attention to this important matter.

It kinda agrees with Winter's statement that they didn't get the bugs out of this vehicle before putting it on the market.
I'm going to see about getting a replacement solenoid valve today. I'll have to bring it in to the dealer to show them the part, or I'll get the deer in the headlights look from them. It will take me 15 minutes to replace and should fix P0299 and P1250. Note: I have the manual for the KJ. I found no mention of this solenoid valve in there. I think it was an afterthought by the engineers.

I went to the dealer to get a new solenoid valve. I unplugged it to bring it in with me to assure I had the right part. Oddly enough, it was warm. Hmmmm, that told me. It must have had current through it. I plugged her back in and plugged in my MAF. I started up the Jeep and the yellow light was out. It's been on every time I've started it for months with P0401, P0299 and P1250. Well, it may be intermittent. I still have the tubing bypassing it. The car sounds different and is more zippy. My turbocharger is back.
I've had a run of really bad luck lately. Maybe, this is a sign that things will be better.
Spring is here and times are good.

I have a 2005 Liberty CRD and would like to get more info on service and repair. I defintely need to do what these post are talking about but would like some drawings and etc.

A good investment is the factory
Keep up with regular maintenance
As it is critical
IE: fuel filter, oil and filter etc
Mine is running strong at 140,000
Miles it's my wife's car
I have a 2002 Dodge Cummins which
Is highly modified

Last year around this time, my 06 Diesel tranny completely trashed, plenum and all, my dealership made several consessions and replaced it all for $2,700, more that half the realistic cost. But, this was right at 101,000miles. This F37 code never came on, had trans serviced regular but D/C would not cover, said Im on my own. Maybe now should send in dealer repair order for total reimbursment?

The F37 is not a code but a recall. Chrysler should have sent you a recall notice.

See post #145 for details of F37. (I don't think it has anything to do with an EGR valve.)

The F37 recall dealt with detuning (mostly torque reduction) the engine and replacing the torque converter and the front pump in the transmission. The EGR valve is a separate issue.
Mar 31, 2013 (9:44 am)
I blew my transmission up out of warranty
Engines are detuned as trans can't handle
ATS makes a multi disk converter and better
Clutches etc so you can put engine where
It belongs. The shop that built my truck
Trans charged me $1500.00 for my wife's
CRD including a better torque converter

This EGR thing is to reduce Nitrous Oxide. This is from Wikepedia:
"By feeding the lower oxygen exhaust gas into the intake, diesel EGR systems lower combustion temperature, reducing emissions of NOx. This makes combustion less efficient, compromising economy and power. The normally "dry" intake system of a diesel engine is now subject to fouling from soot, unburned fuel and oil in the EGR bleed, which has little effect on airflow but can cause problems with components such as swirl flaps, where fitted. Diesel EGR also increases soot production, though this was masked in the US by the simultaneous introduction of diesel particulate filters. EGR systems can also add abrasive contaminants and increase engine oil acidity, which in turn can reduce engine longevity.
Though engine manufacturers have refused to release details of the effect of EGR on fuel economy, the EPA regulations of 2002 that led to the introduction of cooled EGR were associated with a 3% drop in engine efficiency, bucking a trend of a .5% a year increase."
The new Chevy Cruze diesel has a urea tank. This is from the dieselhub site.
"Urea or DEF (diesel exhaust fluid) injection is a key component of the SCR (selective catalyst reduction) emissions system for the 6.7L Power Stroke & 6.6L Duramax. SCR is one way that manufacturers are combating diesel emissions in order to meet/exceed current regulations. SCR is a system that reduces NOx (nitrous oxide) emissions by injecting diesel exhaust fluid into the exhaust stream. DEF, also referred to as "reductant", is a solution of 32.5% urea and 67.5% water. Its moderate urea content is where it gets the slang term "urea injection". DEF is injected via a dosing module (injector) into the SCR portion of the exhaust. It is atomized with the exhaust stream by means of a mixer, which resembles an auger welded inside a small section of exhaust pipe. The heat of the exhaust causes urea to split into carbon dioxide and ammonia. Exhaust then travels through a ceramic catalyst where the reduction reaction occurs, converting ammonia and NOx into nitrogen gas (N2) and water" (H2O).
Is the urea thing a better way to go than the EGR? It seems like it would be better for your engine. It also seems like it would be a pain to have to fill a urea tank as well as a fuel tank. There would be extra cost for this consumable item. If this is required in future diesels, this could be a big drawback.
