2006 Liberty CRD no power in any gear

I posted in another forum and have not gotten a response, but below is a post from 2012 that is the exact same symptoms I am having. There was no follow up or documentation of a solution. If anyone has experienced the same issue please let me know what you found.

"Greetings,
It seem that my transmission completely disengaged ( for lack of any other way to describe the phenomena) while I was driving on my way to work yesterday morning on the freeway. It didn't come out of gear, per say, it just all of a sudden ceased transferring power from the engine to the wheels (BTW- I drive full time with the transfer case in full time 4 wheel drive). I coasted to the offramp of the freeway and pulled off to the shoulder. I put the transmission into 'PARK' and that worked. I checked the transfer case by first positioning it into 'NEUTRAL' which caused the jeep to roll forward predictably. Then I positioned the transfer case into each position from '2WD' all the way to '4WD Lo'. Each time in each position, the transfer case engaged as it should have normally. Now when I tried all of the transmission positions ('R' 'D' '2' and '1'), the vehicle wouldn't move forward and acted as if it were in 'N'-Neutral and the engine would just rev up as I applied the throttle. I think I hear a high pitched but subtle whirring whining sound as I rev the engine. The engine seem to run normally. I checked the transmission fluid and it is at the correct level and didn't have any abnormal smell, look or consistency. I can't think of anything else and from the looks of it, it sound like I have a major transmission problem. Correct me if I'm wrong, but I think that I've been told that in some newer transmissions, plastic bands are used instead of gears. Did I break a band? Ok, I'm ready for any and all input and advice from my fellow 'Jeep Forum' peeps."

Did anyone ever confirm that this was a torque converter failure? I have the exact same symptoms. Driving down the highway and it suddenly acted like it was in neutral. Coasted to the side of the road and park works. It feels like it is shifting through all of the gears and between 4w and 2w but no power applied to the wheels at all. Oil level fine. had a TCM code p0868 low oil pressure, cleared it and it would not come back. Still no power in any gear. I pulled the transmission. Oil and everything looks perfect. No leaks, the TC looks fine from what I can see on the outside, no issues with the transmission input or output shafts.

I am at a crossroads. the 2006 CRD has 179k on it. The TC was replaced at 120K. Do I tear apart the transmission and rebuild? Do I just replace the TC and put everything back in? Could this be how a oil pump fails even though the code did not return when I tried shifting through the gears with no power to the wheels? Could it be something else like a bad solenoid even though I don't get any codes? Any help would be appreciated if someone has had a similar situation. This old thread was about the only google result that was exactly the same symptoms of my driveline issue. It would be good to document the solution for this kind of failure.

Have you checked the spin on filter is tight & that the seal hasn't blown or split? It will cause low oil pressure & the transmission will put itself in neural so you wont get any drive in any gears

Unfortunately it looked like it was good.

Yesterday morning in SD, 0°F, I went out and started up 2005 Jeep Liberty CRD Sport, let it warm up. Went out to drive it and nothing but 'Park'. I tried all fwd options at all shift points. Nothing but revving, no noise. I did notice later when I tried again, the motor seemed to be idling totally effortlessly.

I suspect torque converter. It was working fine and is original, 193,000 miles.

About 8 years ago, I had the transmission services with pure synthetic, per.

Thank you in advance for any help or insight into this issue. L

Did you try placing the transfer case in 4 wheel drive to see if it made any difference? :idea:

Yes

Well, that kinda rules that out!

More possibilities:
Could be the front pump inside the transmission has failed (no fluid pressure). Would act the say way.
Have you checked the transmission fluid level or try adding some extra fluid to the transmission?

There has also been a few rare of cases of owners finding the inner screw on fluid filter (has plastic nipple) breaking off and causing total loss of fluid pressure.
I replaced my filter nipple with a metal one from Geno's Garage for this very reason.

Update. Jeep was in extreme cold. It is much warmer today. I hooked up a chain to position it to tow.

Transmission is working? Can I trust it? Could condensation have built up and froze something, now thawed?
What could be going on?
Thoughts?
Thank you, in advance.

I would service the transmission or have it serviced, replace both filters and new ATF+4 and overfill the transmission by 1/2 to 1 quart.
This should remove any moisture possibilities.

Thank you. Went out, stopped again. I did view a YouTube video and this fellow had the identical experience. He upgrade to that metal filter connector/upgraded filter and full service including second filter. With any luck this will be it. Thank you for all the help!
