Ok so for the past few weeks my temp/overheat light comes on randomly. Sometimes it comes on and goes off within a minute but twice now it has stayed on until I turn off the truck. The temo gauge never shows that I'm running hot, it is always sitting right where it should be, just a hair under halfway.
I have checked coolant levels and electrical connections and everything seems ok. This is for an 06 4.7 non-ho

 

There is an overheating light?

 

Maybe explain what the light looks like, many people get the engine temp light mixed up with the transmission temp light.

If its the engine temp light, it might just be a faulted sensor, the warning light and cluster gauge are two separate sensors.


If its the transmission light, (red circle with a flag in the center) then its probably just a random error that these trucks get. I still think its a factory built in timer for the scheduled transmission service, but have no way to prove it. (Mine only freaks out like that for a week about every 20,000 miles) Always turns on randomly, then goes away like a min latter, usually like after a short trip to work, or the grocery store.

 

You are correct sir....Upon further inspection it is the trans temp light. It is a circle with a kinda flag/capitol F inside it right next to the 100mph mark. Mine also usually only does it on short trips.
Is there a sensor that controls this?

 

I too am having this problem. I noticed that you and Eimir123 both have the superchips controller. What setting are you using, because I started having this problem after using the tow setting. I changed the trans fluid and filters and had the light come on while sitting at take-out line. It may be the programer settings???

 

I've been doing a little research on the site and came a cross this thread, https://dodgeforum.com/forum/3rd-gen...ion-issue.html, I'm going to check this out this weekend, I kinda see a correlation with a/c use and warning light coming on.

 

I disconnected the battery and it hasn't come back on.

 

would this happen to look like what you are seeing?

 

My truck too, just joined the random tranny temp light club at 62,000 miles. I was reading another thread about a sensor going bad in the trans oil pan, but ill have a look at that computer by the condenser and will see if that will solve the problem. Although, my tranny is due for a fluid and filter service but the fluid levels are fine but ill have a look at the sensor too when i drain the tranny.

 

ok so update from my end (ill edit this when i get the full list of what they replaced back)

I hauled my truck in on the tuesday, 21st and they said that i was 2.5 quarts low on transmission oil. the following weekend i saw the pic i posted above. Printed it out, then on this last tuesday, 28th, and they said i have a bad torque convertor (or an oil pump of some sorts), bad solenoid packs, and i needed new transmission oil lines. WTF Over??? Parts wont be in till after labor day weekend. FML

We will see if the new lines will actually do any good.
