#486 of 1101 2007 Jeep GCL Transmission Issues
Nov 19, 2009 (2:07 pm)
I have read of this problem in other posts but did not see any threads with the answer, I am hoping someone knows what the malfunction and fix maybe. I bought my wife a 2007 Jeep Grand Cherokee Laredo 4x4 in 11/08, the vehicle had 27,000 mile on it and was still under warranty, now prior to going out of warranty about 8 months later she was driving her vehicle to work when she said the "Check Engine" symbol lit up plus some other dash symbols the engine was still running but she was getting no power to the transmission she pulled the vehicle to the side of the road, shut the engine off waited a few seconds - started the engine and everything was back to normal. When she came home that night and told me of the incident I checked the vehicle out and also took it to the local Dodge Boys to have them run a diagnostic - according to the shop there were no problems. Now the vehicle is out of warranty and this same issue has happened to my wife several times and I could not get the vehicle to repeat this issue nor could the local Dodge Boys. I had read some posts that there could be programming issues with the TCM or PCM and to disconnect the battery for 5 minutes and let the system reboot - I did this and had no issues for about another 6 months - in the past month this has happened to my wife twice and the other day it finally happened to me - luckily I was less than 100 feet away from Auto Zone and was able to have them run a diagnostic which came up as U0404 and said something about bad data from the transmission. If anyone can be of assistance please let me know unfortunately like a lot of Americans I find myself economically in a bad situation and cannot afford to trade this vehicle in.

That could be a sensor on the tranny that's not giving the right signal, or like you said about the TCM it might not be reading the data right.
You should see if you can have a mechanic hook a snap-on scanner to it, like my brother's, because it does a troubleshooter on that code and give you some ideas on where to start. You could also check the sensors connections if they are corroded or damaged, but I would look into the troubleshooter first it helps alot.

I have serviced my own trans fluid several times. I concur with cecarter3. He's right. You need to do a flush if you want to completely swap out the fluid.
Ask if there's suppose to be a magnet in the bottom of the pan and if not, is it OK to add one. It collects any small metal particles that are created. I've seen magnets with a lot of grit on them.
If you have to prioritze your budget, get the trans filter swapped out first.
The dealer will be your most expensive choice, but they will actually do the work. Anybody else, ask for the old filter and when you go home, verify it came from your car.
If that doesn't fix your problem, I suspect that the transmission and engine are not interacting properly when the engine is cold.
#490 of 1101 2001 Grand Cherokee Trans Code 0740
Nov 21, 2009 (6:31 pm)
I have a 2001 Jeep Grand Cherokee 4.0L, 2x4. The transmission has been slipping. The code came up 0740 pointing to the torque converter. I replaced the Pressure transducer, Pressure solenoid in the governor, fluid, new filter and I drove it for a few days. The slipping seemed to be gone. Then the transmission icon on the dash came on. This was the first time it came on, with the prior slipping it did not. The same code 0740 came up again (AutoZone).
I drove the vehicle on the freeway for about 35 minutes. At my next stop, I had no reverse and there was smoke coming out of the transmission stick tube. Since that time I have continued to drive it to work about 10 minutes away. I never go over 35 mph. I hear this rubbing, whining sound about seven minutes into the drive.
Now here’s the kicker. Yesterday, reverse started working again. if the torque is damaged, should reverse gear be going in and out? and if it is NOT damaged, what sensors or valves or electrical parts need to be replaced? Or is it now time to drop the dreaded transmission? Sorry for so much detail. Thank you in advance.

A damaged torque converter shouldn't affect reverse but the whole tranny. I would think If the torque converter was damaged that it wouldn't move. On my jeep there is something I think is a sensor, i'll look, it's on the bellhousing. I'm not sure if a vavle engages reverse or a solenoid, my guess would be a solenoid to engage reverse, but i'm not sure i'll see what I find. Also is the tranny getting really hot maybe it's not getting fuild at the right spot, if that's the case something could be burning up. Have you had it to any transmission specilists yet, that would help. And what model is it that will tell you a lot.

I serviced my 97 jeep transmission last summer and I swear I had enough fluid in it, but my mechanic said it was low. Added fluid and problems went away.
It would be interesting to know how the transmission cooler is suppose to work and if it is OK. Is it under pressure like your cooling system and how can you measure it?
As a precaution you might want to verify that the filter is keyed by shape or bolt pattern. There's not enough space here for all my mistakes.

Does anyone know why code 26, Governor Pressure Sensor Offset Drift, for the tranny would be coming up?
#494 of 1101 2000 \jeep Grand Cherokee - transmission slip when turn left only
Nov 23, 2009 (11:23 pm)
2000 Jeep Grand Cherokee 4x4 6 cyl. When I make a left turn, the transmission seems to slip for a few seconds then catches and goes into gear. Only happens on left turns. Took to transmission place and they found nothing. Transmission levels are fine

I think that could be somthing to do with the rear differention slipping in the turn when all the weight is on the right, because that makes no sense why the tranny would only slip on left turns. It's a thougt!
