Hey all, I really really hope someone has some direction on here, as I'm about ready to throttle this so-called "dealer" I have my Jeep at right now.

The description may be a little long, so please bare with me.

Jeep Commander - 2007 - approx. 58,000 miles

About a year ago, my Commander started having this really strange issue where it would drive completely fine some days, but other days when I went to start it, it wouldn't make any sort of crank or catching sound, it just wouldn't start at all. All of the lights on my dash would flash, and then the "malfunction indicator light" would light up, and the little output screen where my mileage would usually read would light up with the "Transmission over Temp" message. After reading this and other similar forums, I read somewhere about leaving it to sit for 30 minutes because someone figured out with their own Commander that it was an issue with the key being locked out by the security system. Letting it sit worked for me, so I began using the spare key that I had, and the issue stopped.

Now, two weeks ago, out of nowhere, the issue is back but slightly different. We were out of town, and the Jeep had been driving like a champ. It had even just before we left had its inspection, oil change, and total fluid change. Friday, we were fine, and Saturday, we were okay. Sunday, it did the same thing a year ago with the no start/malfunction light/trans over temp message. We let it sit for 30 minutes as we had done before, and it started up, so we drove where we were going for the day. About 4 hours after we got to our destination, it was doing the SAME thing again. We let it sit for 30 minutes again, and this time it still wouldn't start. So we went to dinner, came back approximately 1.5 hours later, and it was STILL doing the same thing. So by then, we knew we were stranded for the night, so we stayed at a hotel. The following day ( approximately 11 hours after we had last tried it), it was STILL doing the same thing! So I did some more googling and came across another solution. I unhooked the negative terminal, put the key in the ignition, and turned it to the "on" position for 5 minutes. I then took the key out, rehooked the negative terminal, and tried to start the car. This time, it did start. Luckily we were able to get home without needing a tow.

Not even an hour after we got home, it wasn't starting again. And this time, the negative terminal trick did not work. It started and didn't start intermittently for the next week. The following week I just worked from home and didn't even drive it for fear of being stranded somewhere again.

This week, the dealer local to us was FINALLY able to get my Jeep in. It luckily started the day I was to take it out to them (Monday) and drop it off and give my explanation of the issue. Yesterday and today both, they're calling me saying it's starting ideally every time they try it, and of course, they can find no codes on their systems!

I'm really at my wit's end. I can't drive this car around, knowing that at any moment, I could be stuck somewhere again. Does anyone have any suggestions? Does anyone (hopefully) have the same issue that got resolved for you? A mechanic that I am not, I'm a little pissed that the dealer mechanic has not tried anything other than trying to get it not to start. I mean, really, how did they fix cars before there were so many damned computer codes? It seems to me that he should be testing things like the starter, transmission, security chips, etc., for points of failure even if he can't replicate the issue.

Well, if you've stuck with me this long, thank you! I look forward to everyone's suggestions!

Sorry to drag this back up but I'm having some 'trans over temp" issues that don't necessarily match any of the other issues people have been describing here with it, and are really getting irritating. And yes I'm new so I hope this is an appropriate location.

About a month ago my wife's 2006 5.7 Limited (64,000 miles) popped the "trans over temp" message while driving at work. When the message appeared she said the jeep automatically revved up almost to redline, clunked really loud and seemed to lock her into gear so it wouldn't decline at all or downshift when braking. All the while smelling of horrible burning trans fluid. She called me to come look and I drove into town, saw the message and though if I turned it off maybe it will reset. So I turned it off and unlike a lot of the problems associated with this message that I've seen described on the forum it starts right back up minus the message and drives fine. The Jeep drove fine the rest of the day. The following day on her way to drop off the kids it popped the message again with the same symptoms. When she got to her location she turned it off like before and restarted and it was gone. I told her to take it to the dealership to have it looked at. On the way it popped up again with the same symptoms. Luckily it's under warranty so we figured just get it fixed.

So it's at the dealership for a week and they finally say the tranny is toast and needs replaced. The dealership orders the tranny which takes another week to get in and get replaced. On the tech's test drive it throws the message and grenades the new tranny. So... another new one ordered, takes a few more days and get it replaced really quickly as it's approaching 3 weeks at this point. Everything appears to be normal so we come pick it up. On our way home message pops up, rpm's start to scream and the jeep smells like it's going to explode. So... back it goes. This time they apparently had done some research and found where people were having problem with starters so the dealership hastily replaces the starter and associated wiring and declares it "good to go" and hands it back over.

Well, you guessed it, after picking it up AGAIN this morning, it did the exact same thing. Same message, symptoms, and smell. So... another return we've made. I told the service manager this morning that this vehicle is absolutely unsafe and I won't be taking it back unless he can prove it is fixed. Problem is, I know that's unrealistic, though, how am I suppose to let my wife drive this with our kids in it? I mean, wouldn't let ANYONE I know drive it at this point.

I don't really know where to truly go from here so I figured I'd see if any one here had any really detrimental things such as this occur in association with this message. Any advice, direction, or ideas I can get them to look at from here would be really appreciated. I'm not sure what to do with it as they obviously are too incompetent to find the real problem and fix it, and I just can't trust the vehicle. If you've made it this far, thanks for reading and any advice.

No Start condition (Transmission Over Temp error)

Just thought I'd post about my recent experience with this weird error.
I just went through this back on Monday 07/23 and it was very frustrating , to say the least.

First, some background, it had been another extremely hot day here in the northern suburbs of Chicagoland. Temps were approaching 100F for what it felt like the umpteenth time. I had just parked the Jeep in the stifling garage, it felt like a blast furnace in there. I left it in there for about 2 hours. I was going to go out and hopped into the Jeep and noticed the EVIC displaying Transmission Over Temp. I tried to start it up but no chance, it was completely dead. Shortly after that it, everytime I would turn the key all I heard was relays clicking and saw the instrument panel indicators and interior lighting flashing on and off. I didn't what to think of this. I figured I'd take the error message for what it was worth and proceeded to push the vehicle out of the garage and left it out on the driveway to cool down. After another couple of hours, I went back to try to start it up but no luck. I popped the hood and measured the battery voltage, it was 12.5V. I checked the engine oil dipstick and tranny dispstick, all seemed OK there. I then proceeded to google this error, some sites had mentioned the cause as being any one or combination of the following: (A) bad starter (B) bad starter wiring harness (C) ASD relay

I have the FSM in hand but was reluctant to start messing with this at this time so I let it sit outside overnight in hopes that it would start up the next morning. The next morning came and went and it still wouldn't start up. I even tried jumping the battery with my wife's vehicle and nothing. I went so far as to try connecting a starter/charger in hopes of getting it to at least crank and all I heard was the clicking of the starter.

Was losing hope and also going to lose a day of work, so I had it towed to a local repair shop. By the time they got around to look it at the day was almost over. I finally get a call in the evening and they told the Jeep was ready to be picked up. I went to pick it up and asked the mechanic what was the major malfunction, he said it was the battery. I was dumbfounded, I couldn't believe it was the stupid battery. The Jeep is an '07 with 72K on it. Perhaps it the battery's time to go, I would've never guessed a battery failure would cause these weird errors. Ended up with an Interstate battery with a bit more umph (1000 CA & 800 CCA), at least it wasn't something more serious.

As an update, I stopped by the dealership after not hearing anything from them since dropping the Jeep off AGAIN last Saturday. Including numerous calls that were never returned. They informed me that they had been working with the "tech line" to figure out what was wrong being that they had never had this problem come up and couldn't figure it out. The "tech line" apparently instructed them to run a series of tests on our Jeep which apparently were an epic fail. Based on these results the "tech line" guy (whoever that is) informed them to replace the PCM. So, since the friggin PCM is a special order, they're telling me it's gonna be a week to get it, then programming time. So... we're looking at it being 7 weeks total it's been at the dealership until we get the Jeep back after this epiphany of a diagnosis (minus the 36 minutes I had it back prior to it screwing up again), and hoping it actually works. If it doesn't, who knows how long it'll be til they come up with they're next miracle fix. It would be nice to actually get my Jeep back fixed and feel like it's safe enough to let my wife drive it, but I'm not holding my breath. I'm not sure these techs could find a noodle in chicken noodle soup, and frankly I think they're all a bunch of criminals. I'm about to write Jeep off all together. I surely won't ever buy another one after this, and if it ever gets fixed I think I'll just trade the POS off. It's too bad, I really liked my Commander when we bought it. I guess I'm reduced to letting them blow money on warranty work indefinitely until they either fix it or put it down for good.

I have an 07 Commander with about 62,000 on it. Last week I got the "transmission over temp" and read to just let it sit so I did. That didn't work. I then read it could be the starter so I had my wife turn the key while I knocked the starter. Sure enough it started up so I figured it was the first time and I would ride it out. It happened to my wife last night so we did the same thing and it started up. This morning I went and got a new starter, installed it and it worked great. I went to the store 6 hours later with a new starter and it happened again. I still haven't found a clear answer, maybe it's the contacts but its dark and I guess I'll check them tomorrow but this isn't good.
I have a 08 XK and I had the same problem. It was the Starter Wiring Harness. I think everytime u hit the starter it moves the harness Little enough for your XK to start. The Harness collects a lot of corrosion and is known for it. Climb under the XK and move the harness alittle and see if it starts up again. Just a suggestion. Good luck and keep us informed. Steve.
Fellas i am having the "transmisson over temp" issues as well. If you are having the same issue please take the time to read my long post.

Got my 07 3.7 with 63k miles and never had an issue until about 8-9months after owning it and it happened in the driveway on a hot summer day. Did some research here and read that it is possible that one of the wires could be lose so the next day I jacked it up, got under and found the wire, i pushed it in and sure enough it started right away.

To test this I got under again and pulled the wire/spade connector out a little (it wont pull out totally as I tired) and as I thought it didnt start, back again about another 5 time pushed in it started, pulled out a little it didnt start ect. So I assumed this was the issue without any other issue.

Come 4 months later it happens again with my wife an 1.5hrs from the house with my girls and mother in law, I load my car with jacks and tools ect and its been 2.5hrs by the time i get out there and I get in and it starts up right away without messing with it and I follow her home. Its working so I am assuming that its prolly the same issue with the lose connector so I get under the jeep and pull it out a little like I did in the summer and I am thinking its not going to start, well WRONG it starts up right away, I could not get it to not start at all after trying 4-5 times.

One month later my wife asks me to go grab a gallon of milk at cvs so it cold out and I remote start it (mind you it seemed weird because it took about 6-7 seconds after the horn beeped which I thought was weird right away). Get to cvs grab the milk wallk out and get in the jeep and guess what its not starting with the trans over temp message. I wait 10min try and nothing, i way 40mins try and nothing, i wait another 20mins and it starts up right away like nothing is wrong. Come home and try to mess with the connector again trying to get it to not start as the previous time and again I cant get it to not start.

Now this brings me to tonight, we planned on going to get my daughter a hair cut after dinner and my wife jokes watch it not start and we will be stuck but I laugh and say I'm not worried and sure enough it doesnt even start in the garage. WTF is going on, try it 3-4 times and nothing. We leave the jeep go get her haircut and come back so prolly 40mins later and I try to start it and nothing.

I have done some research and was unable to really find any specific pictures that my assist, I am limited with my research time on the forums with work, family ect. My goal it to try to get to the bottom of this and document it every step of the way so I can post it for other members that my be having this frustrating issue with their jeep commander that I still love, as least for the time being haha.

I will keep you updated fellas

hello, every one I have desame problem right now with my Jeep commander 207 67k miles(transmission over Temp) I took it to transmission garage no response yet more advice.
Transmission overheat message

My problem was the rear differential was leaking setting of the error code. Have not had it happen in over 2yrs since replacing seals and fluid.
I'm having this problem now, I'm losing my mind over it. I recently had my a/c lines replaced and it was fine for about 5 days after. Last night I was leaving for work and it wouldn't start, I came to the forum for help and after letting it sit for a few hours it started right up and then again this morning. I took it out today to see how it was running and had no problems, that was around 830am. Then at 1030ish it wouldn't start again. So I let it sit a few hours and it still won't start. I tried disconnecting the battery, didn't work. Can anyone help me out with the location of the starter and harness? I appreciate the help

Yeah, from my experiance 5 years on a battery is all you get, I got 7 years twice, you get what you pay for. Good move on the 1000 CA & 800 CCA, I always go that routewhen available, they seen to last longer.

No issues after you replace the battery?
I have an 07 Commander with about 62,000 on it. Last week I got the "transmission over temp" and read to just let it sit so I did. That didn't work.

Slaughter; Did you ever get this fixed? Any updates? So it wasn't the starter? Could have just been a corroded connector to the Starter Solenoid?
I had the Transmission over temp message come up on me today while I was driving up a mountain and back down, after coasting down the mountain in neutral and riding the brakes for awhile it went away. Would having put the bigger tires on cause this problem by making the tranny work harder to turn the wheels?
Hemi; did this Transmission over temp message ever raise it's ugly head again?
I found that TSB and, though it is listed as a tsb for 2007 XKs, when you read it, it's actually for the 2006. (It is numbered 08-060-05, fyi.)
We are having the no-start, flashing dashlight issues with our 2007 with 83K, same as geekehnikeh. We just bought it used from a large and well known dealer network in our area only 6 weeks ago. I am taking it in to a non-dealer mechanic tomorrow along with some of the above posts to see what he thinks. He was upfront with me about not being able to help if he can't get it to present the problem. It has been intermittent. Though so far we can get it to start by disconnecting the battery and reconnecting in after a few minutes. We tried this based on a hunch that it might be a sensor/computer miscommunication problem. It might be a fluke that it worked though, from what I am reading above.

I'll repost tomorrow evening with whatever the mech finds.
csmmom; Did you get this fixed? Any updates?
bought my 2007 with 25000 miles on it and drove it about 200 miles then it would not start after my wife stopped to get kids from daycare. it has been at jeep dealer for 5 weeks as of today, just sick, they canot get it to start, it will start and run with remote engin start b ut dies once key is put in ignition. the morning after i towed it in dealer said they could not replicate and that it was starting. i went out started it turned off and it wouyld not start so there it sits. will let u know what was wrong if they ever figure it out.
goodfella; Did you get this fixed? Any updates?
soo has anyone discovered what is the cause for this no start trans overtemp error??
is it the key, ignition switch, trans temp sensor, starter wiring, starter, or bad connections on the wiring?? i need help with this cause my wifes jeep has done this 3 or 4 times now and i need to fix the actual problem i just dont wanna throw parts at it and not fix anything.. thanks for the help

Eric
slickjeep; Did you get this fixed? Any updates?
I am having the same issue with a 2007 Commander 3.7. Only difference being it will flash the Transmission Over Temp and then crank over with out firing. It only does this after being warmed up, so far has never done it cold.

What is this Front Controller Module that was mentioned above?
ncs; Did you get this fixed? Any updates?

fnkychkn;"The Front Control Module (FCM) is a micro controller based module located in the right front corner of the engine compartment. The front control module mates to the power distribution center to form the Integrated Power Module (IPM). The IPM connects directly to the battery and provides the primary means of circuit protection and power distribution for all vehicle electrical systems. The FCM controls power to some of these vehicle systems electrical and electromechanical loads based on inputs received from hard wired switch inputs and data received on the CAN bus circuit.

OPERATION

As messages are sent over the CAN bus circuit, the Front Control Module (FCM) reads these messages and controls power to some of the vehicles electrical systems by completing the circuit to ground (low side driver) or completing the circuit to 12 volt power (high side driver). The following functions are controlled by the FCM:
Air conditioning condenser cooling fan
Daytime running lamps - if equipped
Fog Lamps
Front and rear hazard warning lamps
Front turn signals
Headlamps
Horn
Radiator fans
Rear window defroster power and timing
Stop, turn signal and tail lamps
Windshield and liftgate wiper and washer systems
The FCM provides the following features for the above function:
Acts as a link between the CAN bus network for critical powertrain, anti-lock brake systems, electronic stability program systems and the network for body and interior modules.
Controls the wipers based on messages on the CAN B bus from the rain sensor module (if equipped).
Controls the adjustable pedal motor on non-memory equipped vehicles.
Controls back-up lamps.
Flashes lamps in response to turn signal, Remote Keyless Entry (RKE) and Vehicle Theft Security System (VTSS) inputs.
Illuminated approach feature that turns the headlamps on when the vehicle is unlocked with the Remote Keyless Entry (RKE) transmitter.
Minimizes voltage variations to the headlamps to extend bulb life and to equalize the light output from the lamps, which might otherwise differ due to variations in wiring resistance.
Monitors battery voltage and turns off non-essential functions such as the fog lamps, rear window defogger, and heated seats if necessary to conserve battery power.
Operates the high-beam headlamps at reduced intensity by pulse-width modulation of the power supply to provide the daytime running lamps.
Protects the battery from discharge if the headlamps are left on, by automatically turning them off after eight minutes.
Provides ambient temperature sensor information.
Provides A/C pressure transducer information.
Provides brake fluid level information.
Provides washer fluid level information.
Provides the variable delay intermittent windshield and liftgate wiper time delay features, and the vehicle speed sensitive windshield wiper delay variation.
Sounds the horn in response to RKE and VTSS inputs.
Turns off the horn in the event of excessively long operation that could otherwise damage the horn.
Turns off the windshield washer motor after 10 seconds of continuous operation to protect the motor.
Controls headlamp washers (if equipped).
Provides wheel speed information on non-ABS equipped vehicles.
Stores vehicle configuration data.
