#136 of 176 Tranny Problem? by sjmartin86

Sep 30, 2011 (7:05 pm)

First time poster here so hope someone can help. I have a 2005 Jeep Liberty Limited 4WD and my wife was driving down the highway doing 65 and it jerked hard and when she pushed on the accelerator it just reved up like it was in neutral. She pulled to the median and called me i told her to try pulling it into first and it would pull a little but was bogging the engine down so then i told her to put it in 4wheel hi and the front tires started spinning like they were trying to pull the jeep by themselves. So long story short i got off work checked it out and it will not do anything in reverse but in drive it tries to pull but boggs engine and hesitates. Please anyone give me some idea if its tranny or transfer case or something else

Gee I wonder if you busted a differential....

The diff is fine.
 
Around 79K miles, the TCM was throwing several codes and they replaced part # 4799758-ad sensor. Apparently this is the one and only, but I am not a tranny expert (obviously from my other posts). The replaced line pressure sensor resolved my problems for about 9K miles.
 
Now at 88K miles, I am getting P0700 (MIL request from TCM) and P0714 (transmission internal temp sensor intermittent).
 
I am looking at the service manual for the 545RFE. Can anyone verify/validate for me that the internal fluid temp sensor is integrated into the Transmission Range Sensor (TRS)? if this is true, it looks like I would have to pull the valve body.... but is the TRS integrated into the valve body (i.e. do I have to purchase the whole valve body new) or is the TRS a replaceable/separate component?
 
Does this make sense?
 
*update* crap, looks like a $380 part and few hours of wrench-time, correct?

I forgot one very important note to my last post.
 
I bought a ODB-II code reader, when my tranny started acting up around 88K miles. When I reset the codes, the transmission shifts like it just "rolled off the factory line."
 
It might be two minutes, two hours, or two days later; and it sets P0700 and P0714 agains and starts shifting roughly.
 
Rinse and repeat. Same random results.
 
Is there a way to splice a resistor into one for the wires from the 24-pin connector an send the TCM the expected voltage, all of the time? I know that's some serious stupid-engineering... but it drives very well WHEN the codes aren't set.

I have 2004 Liberty, simliaar thing happened. It ended up that the throttle sensor was gone and resulted in burning out the clutches in the tranny. Long story short 57k miles and a 2250.00 bill for a new transmission! I was not thrilled. This happen this week, Wish you luck.

Hi there. I come seeking your advice. My 2004 Liberty seems to have a bad clutch. It has 78K miles on it and I have never done any sort of service on the clutch. I am not sure if it could be the transmission which is why I came here hoping you might help me.
 
It was loping for a couple days in the lower gears after the clutch was disengaged. Then finally, it wouldn't pull the car at all in any gear.
 
The dealer wants $1200 to replace everything (his words) and $900 to just replace the clutch. My questions are these:
 
1) What does a clutch problem look like as opposed to a transmission problem?
 
-and-
 
2) Have you seen this sort of problem resolved and if so, how?
 
Best regards,
 
Damien Riley

Well if you mean you could put the car in 1st gear easily, lift on the clutch, and the car didn't move, then yeah, you need a clutch and maybe a flywheel resurface.
 
If you mean you can't GET it into any gear anymore, then you may only need a clutch hydraulics overhaul, which is a lot cheaper.

Thanks a lot. It does go into gear and not slip out. BUT, it does not disengage and move the car. Does this sound at all like a transmission thing? What would the differences be in symptoms? My instinct tells me it is a clutch replacement thing.

Hard to say not being there myself. Maybe the transmission shift linkage has fallen apart but I doubt it's an internal transmission problem.
