2006 Commander Transmission Over Temp

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

If it were me I'd install a trans temperature gauge for about $50 and get the real story. Maybe the trans guy would have a spare one you could borrow?

2006 Commander Transmission Over Temp

This same warning came up on my wife's Commander last weekend.

2006, 4.7L V8, 55000 miles.

I had the trans serviced and they found the fluid a little low both otherwise no issues. New filters and fluid and the same warning came up on the highway on Saturday.

The warning light stayed on for a bit but before I could get off the highway it went out.

No issues with shifting. No issues with starting.

I'm starting to think about maybe installing a temp sensor, but I just had the fluid changed so I don't want to do that right away.

I started a new post about this myself... Mine is displaying, but the transmission is also disengaging (kind of like knocking it into neutral while driving down the road) when it is happening as well... I am starting to not trust me Jeep and don't know what to do...

Perhaps something to do with the transmission range sensor...I'd start there.

Mine seems to be a different problem from yours. I get an intermittent warning message - 5 minutes after start up yesterday - that turns off after a bit. No issues shifting.

The issue started the day after I pulled a power line off the ignition for a handsfree phone. I can't imagine the two are related, other than a coincidence of timing.

I've read other threads where this is related to a faulty starter, but I've had no issues with starting. I replaced the battery just out of caution two weeks ago. No idea what else to do.

Just an update. I took the Jeep back in because the warning light kept coming on intermittently.

The shop checked and the trans was running hot. The radiator fan was shot and was not cooling like it should. Replaced the fan and hopefully we're done with this.

After the fan went in, the trans temp stayed where it should during their diagnostic drive.

Warning popped up again briefly today so I spent some time on the phone with the shop.

They said that when they were monitoring the temp they would sometimes see it pop from 160 to 300 and back down.

I've got a bad wire somewhere in between the sensor and the ECM. I have no hope of that ever being located...

All three of you that posted having this issue have 2006 Commanders. I have a 2007 Commander 4.7 with 138,000 miles and never had this issue. And my jeep has seen a lot off off road and beating on in its life
