Not sure if this is helpful. I own a 2005 libery limited crd 78k miles. Recently had the same problem and the ECM threw two codes: first code was transmission control module and the second was related to rapid changes in transmission fluid temp. The dealer replaced a line pressure switch and everything is back to normal. Shifts are normal.
Now however I am having trouble with the transfer case. 2wd is fine. 4wd full time cause the vehicle to grind to a halt. I can only describe the feeling as though the brakes are applied. I can push the accelerator and move the vehicle but it resists forward motion and quickly comes to a complete stop upon releasing the accelerator pedal. Anyone have thoughts on this one? I know that the NV242 transfer case has a planetary gear to allow the front and rear shafts to spin at different speeds while in full-time 4wd. Could this planetary gear be buggerred up?

Check your transmission cooling lines for leaks.

If you want not to put the money into a SunCoast T/C and Transgo shift kit be prepared to be dealing with problems. The 545 transmission was designed for a 6 or 8 cyclinder engine and definitely not one with the torque of a Hemi, but a Hemi is 8 cylinders=4 power strokes and a 6 cylinder = 3 power strokes of torque/power to the TC and onto the transmission as a whole. The CRD Mighty Mite is 4 cylinders =2 slam dunk of pure torque/power to the TC = to a 4 stroke Hemi in the power range. Not hard to understand why the TC's fail, even the recall replacement better but won't last. Now, I'm sorry I forgot to mention this and try this out, put a car ramp under the front wheel and back wheel have someone watch for you when your centered up on both and stop, emergency brake. I've seen this on alot of cars not just our beloved CRDs (most of the time) reach around near the top from the driver's side you will find the transmission breather laying "FLAT". Cut the hose directly behind it and go to the auto parts purchase 6 feet of same size hose and a junction connector/splice connector. Now run the hose first down from the engine compartment route the hose to stay away from sharp and hot items, zip tie here and there, put the union connector and hose you purchased into the transmission breather line ( Dawn soap works great for this task) then I tied ours off onto the brake line box just infront on the firewall on the drivers side as it should be "VERTICAL". Now unplug the battery clean the MAP sensor check Eurekaboy.com for this. Good luck I have alot more to say for mods I've performed and researched 33.5 mpg in town, it'll take 2 years to break even but the little pains and some larger are all gone 1 year and not even a hickup.

I just worked on a friends CRD and it had nothing to do with the transfer case, I found the Turbo Charger failed. I inquired with them both were they performing cool down of 3min from 1800 rpm and greater and pre- warming when 45 degrees colder outside temp for over a min, they weren't. I had to clean the inter-cooler, intake manifold, and EGR. The new Turbo also comes with a flex cooling line. Here is a old military trick for deactivating a turbo that is starting to fail and you can get yourself home and no damage. Take some heavy aluminum cooking foil fold into four sheets thick. Loosen the turbo tube on the passenger side inter-cooler then wrap the inter-cooler like a bowl nice and tight now put the hose back on the turbo is now inop.

Hi,i just bought my first Jeep Liberty (2007).I had the same problem as yours,the truck won't back up while turning the wheels when i'm in Part Time.It grinds and makes all kinds of awful sounds,i have to press heavily on the gas pedal and then it starts to move 10 inches at the time...When i try to go forward while turning to park the Jeep into a parking space...the same crap happens.
Have you ever found out what the problem is?Should i be worry?

Is there more than one line pressure switch? if so which one did they replace? My son is having the same problem with his Liberty.

The t-case wasn't the challenge. My lever wasn't putting the t-case into full-time 4wd and I was feeling bind. All is well now. Issue resolved.
Tranny is a different story, I got to 87K miles and the transmission is now (once again) shifting hard from 2-3rd gear (at approximately 20MPH under light-to-moderate accelaration). It also "bangs" into drive when I move the shift selector to "D". I pulled the codes and one was tranny overheat and the other was the generic TCU code.
Has anyone had this issue? Am I looking at a bad wiring harness or a bad TCU or both?
Thanks for any guidance.
#133 of 176 Engine Modification Recommendations?
Sep 23, 2011 (5:37 pm)
Thanks again to all the regular contributers to this Great Forum. I have done most of the maintenance and repairs on my Jeep myself with some help from this forum and my Factor Service Manuals (Hard Copy Books & CD).
2006 Jeep Liberty CRD - 129k miles, stock everything, original EGR, second engine block/head/turbo/water pump at 40k miles. I plan to change my timing belt before winter and would appreciate some suggestions about what else I shoud do to maximize the life and performance of my gutsy little diesel.
It seems like a good idea to disable the EGR before it creates the big problems some people have reported. There are a few other upgrades that sound worthwhile like the Pro-Vent system. I can't do everything of course, but I am willing to spend about $1,000.00 this time to buy a little peace of mind. I will do all the labor myself with the help of my diesel mechanic brother-in-law.
My transmission has so many miles on it, I am reluctant to invest in a shift kit or other upgrade. No doubt it will need a total rebuild in the not so distant future, but it is working great now. Should I consider replacing fuel injectors or glow plugs or just wait for them to fail?
#135 of 176 2006 Jeep Liberty LTD. Auto transmission shifter problem.
Sep 25, 2011 (4:08 pm)
The shifter goes all the way from park to 1st and back to park without pushing in the button. Also when I put it in park it will not allow me to remove the ignition key. If I remember correctly you are supposed to push the little button on the front of the shifter to get out of park and past drive and back into park again. This just happened out of the blue when moving the vehicle in my driveway.
Any ideas on how to fix this would be great. Especially if I can do this myself.
