Code P0838 4wd mode sensor low by STEELERS_UNION
Dec 20, 2008 (8:29 pm)

So I have this error code, P0838 in the haynes book it say it means 4wd mode sensor low. I can not get my liberty to shift when then speed reaches 35. So basically i can not go faster than 35. I have had previous problems with my 4wd not disengaging in the past. I have no clue what to do besides dynamite. So if anyone out there can give me some suggestions, i would be grateful. Thanks...

Hello Yes, I should have been here when I bought my CRD but its better late then never. I have had this 2006 liberty CRD and it looks like the front pump when
after 26,000 miles. Its out of warranty by 1 month and has been great. If indeed I
can not get jeep to fix this under warranty who makes a good 5 or six speed after market transmission for replacement? I really enjoy the gas mileage and performance I get from the CRD and have realized they is not a reasonable replacement on the market for less the $40,000. So what can I do to fix it so
I don't continue to have problem.

2003 Jeep Liberty SERIOUS manual transmission problem by jeepinneed77

">Okay where to begin....
 
I have a 2003 5 speed manual transmission Jeep Liberty. My truck has been running good up until now. Wednesday driving was fine but thrusday not the same issue. Thursday I went on an errand and notice I have having problems shifting. I felt like I was working against the gears. I fought to get into gear. Sometimes the gears would grind or even pop out of gear or it would shift really hard. That day I took it to a friend that works at a dealership didn't know if he could help me. He wasn't sure what was wrong with it because it wasn't his expertise. I have an on going issue with the transmission mount. When I had my oil change the mechanic there explained that the one of the housings that the bolt mounts to is cracked and needed to be replaced. He told me is wasn't a must-fix-this-minute thing but SHOULD be fixed ASAP. They were suppose to call me about parts and $ but never did. Then I kind of forgot about it. Well my friend that took a look at my truck said that the crack mount could be a factor but doesn't know for sure. He did say the cracked part is a serious problem and needs to be fixed. Upon looking at the crack, I noticed it's the actual transmission mount/assembly and the whole thing would need to be replaced. Oh Boy! But would replacing that fix my problem. Then friday I went on an errand again and it was worse. I had to jam it into gear. I mean all my strength to get into gear. I decided it wasn't safe to drive and turned around to go home. At my last stop sign I put it in neutral and then I couldn't get back into gear. I tried 1st and 2nd and no luck. I ended up having to push my car down the street into my driveway. I really don't know how to diagnosis this problems. I have been told just in talking that it could be A. the cracked bolt mount B. sync rose C. transmission D. clutch E. throw out bearing. Can someone shed some light on this issue because I need my car!!! I am a college student that works full time and this is my only line. Needless to say I need to do something ASAP. Please help.

If you have a 2WD, to check the gearbox you can put the rear differential/axel on jacks, remove both wheels and gently select all gears without using the clutch and engine stopped. Now there is no effort coming from the transmission line, so you can evaluate the accuracy of the shifting mechanism. At this point if you can't shift easily you need to worry
 
Then start the engine without any gear engaged and check for unusual transmission noise. This will tell you the status of the clutch alignment with the gearbox. If the gearbox is severely misaligned you should hear a complaint from the bearings and the splined shaft that reaches into the clutch plate + mechanism.
 
Then you try shifting gears using the clutch with engine still running. If you hear cracking sounds while you shift then you can incriminate the synchromesh 'roses'.
 
All previous tests put no load on the transmission. When you are on the road you torque the transmission in both directions (+/-) and gears may want to 'let go' when they are severely damaged. This is different from synchromesh wear that has a function of putting two pieces at a same speed of rotation just before penetration of the annular splines/fingers/cogs machined on the gears that are engaged. The synchromesh is a 'consumable' compared to the gears.
 
Bonne chance
 
ps: the throw out bearing can only get noisier than usual but will not affect the transmission as such unless it explodes and permanently separates the clutch plates (not seen this yet!). If the clutch pressure plate is damaged, you will feel it with your foot when you press the pedal. A broken pressure plate mechanism will sound like a charm bracelet worn by a very old lady with Parkinson disease.
 
By putting the truck on jacks, you simulate the usual 'stress' on the transmission and suspension elements; if a fixation element is broken, it will not relax into it's original shape.

Same thing happened to my daughter's 2002 Liberty. Driving down the road last week, for no apparent reason, the transmission locks up. Dealer did $300 worth of tests (eat doughnut, drink coffee, read paper, plug in test equipment, come back, read test results, go to lunch, etc..), and said car needs a $2,000 - $6,000 tranny rebuild. $2000 to "open up, poke around, replace gears," or 3-4 more thousand to replace transmission. Too bad, I just put 5 new tires on the jeep. Time to by a Toyota I guess. Too bad.
 
Note: can't do a CARS clunkers trade in as jeep has to be in "running condition." Who was the stupid politician who though of that. This jeep is not just a clunker, it's a $10,000 flower pot .

Transmission Harsh 4-3 Downshift by jerrysf
Nov 28, 2009 (10:48 pm)

My 2003 Liberty Sport has been running just fine UNTIL I took it in for the 60K service. I took it to a dealer that USED to be a Jeep Dealership, but lost that recently when Chrysler lost some dealerships. This dealership told me that even though they no longer sell Jeeps, they still service them and encouraged me to have my 60K service done there.
 
So after I get the Jeep back I notice there's a harsh 4-3 downshift. I bought the vehicle NEW in 2003 and it NEVER did this before. I take the Liberty back to the shop and tell them to fix it. They say they take everything apart and re-check all of their work and that it's nothing that they did. They then tell me that there is a "TSB" about this problem but that they can't help me because they are no longer a Jeep dealership. They tell me I need to go to a Jeep dealership now.
 
#1. Is it possible they screwed something up when they were "servicing" the tranny? What are the odds that this problem just happened to start at the very same time they "service" the tranny but the 2 aren't related? Give me a break!
 
#2. Why should I have to pay for another shop to take care of a problem when this shop told me they could service the Jeep? Weren't they being dishonest?
 
#3. I paid this dealership over $800 when all was said and done for the 60K service! Is it possible they did the complete 60K service when they can't fix this "software" problem that a real Jeep dealership can supposedly easily?
