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.
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 .
#94 of 181 Transmission Harsh 4-3 Downshift
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?

#96 of 181 Transmission Problems
Jan 04, 2010 (1:24 pm)
My 2006 CRD now has 90k miles on it and I have never had any transmission problems that I know of. I don't recall having any warranty work or recall work done at the dealer either. Last week I experienced two (2) similar events that have me concerned. The first time I was in Full Time 4WD and slowing at an ice and snow covered intersection. The tranny failed to disengage, I heard and felt some noise/vibration and it started to drag us into the intersection until I really jammed on the brakes hard and it finally disengaged. The second time I was on drive pavement in 2WD and approaching an intersection. Again the tranny was pulling in idle against the brakes as I approached the intersection. This time I jammed on the brakes hard enough to stall the engine. Once I restarted, the tranny seemed to work OK. About a month ago I had the transmission pan dropped, both filters replaced, and new fluid at my local AAMCO Shop. Since my warranty is expired I try to avoid trips to my Jeep Dealer for service. Any advice or suggestions would be appreciated.

This could be a problem with the throttle control module. The CRD has enough torc it can easy lee over power the brakes if the system is not falling back to ideal.

What happened with this? I having the same problem with my 2003 Liberty Sport 4x4 - took it in for 75K service and got it back with the slip. Jeep won't pay for another dealer to look at it. I feel like this is a service scam and I'm being ripped off and totally inconvenienced. Dealer says they can't do anything about it and want me to plead with Jeep to cover the work as I am past the 70K limit. A minor version of this happened when I previously had the fluid changed (lived in another state), took it back the next day and it was corrected.
Anyone else having this problem and found a solution?
#99 of 181 early shifting
Jan 22, 2010 (10:05 am)
I have a 2005 liberty with 68000 miles.the problem I am having is the jeep shifts in to overdrive too early.when I accelerate it shifts normal but goes into high at about 40-45 mph,but I have to give it more "gas" ,then it down shifts until it gets to around 60 mph.the only way to eliminate the problem is to really get on it from the start,then relax the acceleration when my speed is aquired,then it goes to overdrive.thank -you for any advice. tranny has been recently flushed,but original filter I assume.
#100 of 181 2003 Jeep Liberty Jerks
Feb 19, 2010 (12:16 am)
I started having problems with my Jeep Liberty tonight. When I was on the freeway I heard this "bang" and then the truck jerked, after that I had loss of power, After I pulled to the side I turned the motor off, waited 30 seconds and started the truck, it was find and lasted that way for the rest of the evening. Does anybody know what happen. I am taking it in tomorrow.
