Re: Transmission Over Temp Message 4.7 WK

Since you say that the engine noise is louder at 100 Km/h, i would check for any exhaust leak. The leak could be pointing towards the transmission cooler lines and heat up the fluid, instead that it be cooled down by the cooler.

Re: Transmission Over Temp Message 4.7 WK

Its worth to check, maybe they routed the new lines too close or even against the exhaust pipe.

redwolf698 is on a distinguished road
The transmission over temp message is indicative of a tft over 270F. Any time you reach temperatures that high, you are breaking down the fluid, and causing issues internally. You need a good thorough diagnostics to determine the nature of your malfunction.

Get that fluid changed and get a good transmission diagnostic, not a code reader free job.

Re: Transmission Over Temp Message 4.7 WK

The guy ar the dealer said the transmission guy was busy when I went going to see him tomorrow.

If they tell me some bull like I need a new transmission im going to drive this jeep right into the manager's office and ask him if he still thinks im going to buy a new jeep..

Re: Transmission Over Temp Message 4.7 WK

Sounds like the torque converter isn't locking up and the slippage is generating extra heat and higher rpm at the same speed....especially with prolonged trips on the highway. If this is true, you will damage the transmission if not corrected.

I had this happen on a Chevy S10 Blazer with a 700R4 tranny. It severely overheated and blew a seal. The cause was a stuck brake switch. The brake switch unlocks the torque converter when engaged during breaking.

Re: Transmission Over Temp Message 4.7 WK

The dealer tells me they performed some cooler line flush, it may have fixed the issue, if I get it again it will need a tranny valve cleanup, which I don't feel like doing. I spoke to the transmission specialist over the phone a few times and mentioned to him all the possibilities that were discussed here and it helped.. The noise I mentioned is coming from the 2 front wheel bearings, not from a supposedly stuck 4th gear, they twice took it for a test drive.. No codes showed up or found either.

I will have to fix the wheel bearings now. I'm not sure how this happened at the same time, it feels like the right wheel bearing makes more noise, I remember going off a nasty pothole or some sh!t on the street a few nights ago...Can I can get the parts from rock auto, or are these guys going to pull a fit if I come with those? I wish I had a full warranty.

I drove home from the dealership and did not get a message, which is good news too.

Re: Transmission Over Temp Message 4.7 WK

These are the parts I would need to do a Valve Body job as next resort if the Transmission Over Temp comes back on:

RL166834-AK VALVE BODY, VALVE BODY ASSEMBLY. Transfer Plate and Valve. .
RL166834AD. Chrysler. VALVE BODY, VALVE BODY ASSEMBLY. Transfer Plate and Valve.

05013470AD FILTER, FILTER PACKAGE, SUMP FILTER KIT, SUMP FILTER PACKAGE. Transmission Oil. .
FILTER, FILTER PACKAGE, SUMP FILTER KIT, SUMP FILTER PACKAGE. Transmission Oil. DODGE RAM 2500 (1999 - 2013) # 05013470AD

Does this make sense to anyone? Why would this happen...

Re: Transmission Over Temp Message 4.7 WK

Damn sob message came back again yesterday, thought it was gone. I even my jeep towed due to a battery drain from that boost I gave the day before this message first appeared.

At this point I think it's an electrical bug. If the transmission oil stays at regular temperature would you bother looking to fix this bug?

Does a 4.7 Laredo 2006 WK have an ECM module? I read some guy fixed that module and it helped. The dealer wants me to do a transmission valve job-solenoid, etc..

Any ideas guys? Maybe I need to replace the battery, starter, what the heck.

Re: Transmission Over Temp Message 4.7 WK

Ok, I think I figured out what's going on. I got the transmission over temp message coming home and pulled over about 15 minutes later, left the jeep started, tried every gear while parked all seemed well, opened the hood and checked out the tranny fluid. All normal level around the 2 small circle mark. Perhaps heating up very slowly, perhaps not. I realized right after I put the dipstick back how friggin hot it's in the engine compartment. This is what the dealer could not duplicate or if they even popped the hood open, they did not get to drive it that long...

It's freaking hot in there, I need to ASAP install or replace certain things. The water pump I put in 2 months ago could be the culprit, but perhaps not. All the hear seems to be coming out from the radiator or where that big fan is blowing.

Does this say something to anyone? It's seriously hot in there, perhaps this also why people get this message in the summer only, (I think that's what I read somewhere).

I also think the belt may be going too, it seems to be kind of swerving about a millimeter or 2. What do you think?

Maybe I need to change the tensioner too? There is some serious heat guys..what would you install to let it as much cool air as possible without damaging anything or costing too much in labor.

Perhaps a 8 year old Jeep WK needs some fixing or part replacements at this age?

Should I keep it, I've changed every fluid that needs changing and drive it for 10,000 miles a year. Drives like a beast in the winter, but I never press the gas, great jeep!

Re: Transmission Over Temp Message 4.7 WK

I really think the extreme heat is causing a sensor to feel it and go off. If not that than low voltage in the battery...

Could it be the quick fix low cost Cardone water pump I installed? Can a water pump cause or aid in causing heat? Is it the overused belt? tensioner, radiator? wtf
