Transmission Over Temp on 2006 Commander

Hi,

Can anyone give me some ideas on what could be the problem with my 2006 Jeep Commander when it displays the "Transmission Over Temp" readout on the dash? This vehicle has the 4.7 engine with the automatic trans. Currently 130,000 miles on the odometer. I have owned this Jeep since new.

This is an intermittent problem that has been going on for a few months. There doesn't seem to be anything unusual in the way the tranny shifts. The service garage that does the work on this Jeep said to take it to a tranny shop, as the garage tech said all he can see it that it may be a faulty sender.

I took it to a local shop, and the owner there said the codes don't show much information, and he cannot find anything wrong with the tranny. He unplugged and cleaned all of the connectors that plug into the tranny, and pinched some of them closer together so as to make a better connection, as he has seen that send faulty readings on trannys in the past, but not on this model.

After leaving the shop, I drove the commander for about 1000 miles with no problem, at one point the highs for the day were 111 degrees, and I drove it through the hills, with no problems. Then a week later, in 70 degree weather, driving on a 10 mile trip, the light came on again, I drove straight to the tranny shop and the light was out by the time I got there, about 10 minutes. He checked the codes, and found no new information.

He said he is reluctant to open the tranny at this point, saying he could change the solenoid pack, a cost of anywhere from 700 to 1000k, a price which he would quote when he actually looked up the part if this is what I choose to do, or he could change out the computer. He cautions me to do either, saying he just can't pin point the problem, and doesn't want to mislead me.

I read some of the threads I found in the forum about this and it seems to be a not so uncommon problem, however I haven't found a thread with this problem in a Commander.

Can anyone suggest some way to determine if this is a serious problem before I start repairing things that may not be broken? In one thread a forum member said he purchased an infra-red heat sensor and shot it at the tranny when the light came on, only to find that the temp on the tranny pan was 180 degrees. If the tranny was overheating, would it show on the tranny pan temp with a infra-red sensor, or would this temp be cooler than the inside of the tranny?

The tranny shop owner says the code is coming on at 240 degrees, and I take it he gets this from what the specs say that warning would come on if in fact the tranny was over heating. Perhaps that would help my diagnose of the problem.

Any and all help is greatly appreciated,

Thank you,

Kmackk

Re: Transmission Over Temp on 2006 Commander

Does the commander use the 5-45RFE tranny?
Measuring the tranny temp on the pan should give a very close indication of the fluid temperature, since the hot fluid is on the inside of the pan. 170-180 F is a normal fluid temperature. If it has the 5-45RFE, then the temperature sensor is indeed part of the TRS /solenoid pack. This module cost around $290 (+ new filters/fluid/RTV) and can be done by yourself when you have some basic tools and some mechanics experience.

But the problem could also be related to the wiring itself. If the respected wire shaved through or has an internal breakage, it could fool the PCM and give a false high temp indication.

Re: Transmission Over Temp on 2006 Commander

Milous and Frango100 thank you for the replies,

Unfortunately I did not write down the codes, and since I stopped at the end of day/closing, I know they did not keep them either. I do have an appointment to take the Jeep back in, tomorrow morning.

Where would I find the part number of the tranny? If this helps, it does have the overdrive, and a tow/haul button on the dash under the gps. It also has the 4WD low toggle on the console, and by tapping the shifter to the left it will drop down a gear at a time, and the same going back up.

Thank you

Re: Transmission Over Temp on 2006 Commander

An other member found the PCM at fault. On 2005 and on JGC the TCM (transmission control module) is integral to the PCM. The temperature sensor signal goes to the PCM and this one will trigger the overtemp light.

Re: Transmission Over Temp on 2006 Commander

Powertrain Control Module. Could be that they call it ECM on your module (Engine Control Module).
In my last post the " Transmission Over Temp" text is a link to the thread from the other guy with the same problem.

Hi Milous,

I did retrieve the codes that showed at the tranny shop.

P0218 "high temperature operation" and
P0714 "transmission temperature sensor intermittent".

The Jeep is back from the tranny shop, and the mechanic said he can't justify doing anything at this point, as the codes don't tell him anything specific that is wrong with the tranny, and the filters, and fluid, which he did change, looked good. Also said there is nothing he can find wrong with the torque converter.

So at this point, it is an intermittent problem, with nothing to be found to correct.

Re: Transmission Over Temp on 2006 Commander

The P0714 code tells that there is something wrong with or the temperature sensor, or with the wiring towards it or the PCM.
The wiring should be not too difficult to check, but most probably will not be the fault in this case.
Experiences from others with this same fault point towards the PCM.
Maybe the resistance of the temperature sensor could be measured at the time the problem is there, just to see if the sensor is at fault.
