- A used PCM from Ares Technologies fixed the issue. They had the best price and warranty. They are in California.
They shipped the PCM to Acapulco, Mexico and it was received in 5 days

Here's the story with the Jeep if you care to read
👇🏽
I bought a 2006 Jeep Grand Cherokee V8 4.7l in Mexico for my vacation family wagon. The Jeep had 53k and was in amazing condition.
One thing I noticed when I was inspecting the Jeep was that the dash warning lights came on when I had the ignition on. I cycled the key and the fault went away.
Here are the warnings that appeared ⚠️
Check gauges
Check engine
Transmission Over Temperature
ABS
Everything was good when the car started and drove perfectly.
I was not to concerned because I thought maybe a bad battery so I bought the Jeep
The battery did die on me so I replaced it fault was still pressent
I didn't have any tools to diagnose the car in Acapulco properly so I took it to a mechanic. They replaced the ABS module and butchered the Jeep so picked up the car with more issues. I fixed everything but the failure was still there.
Here's what I did as routine maintenance since I bought it
Oil Change
Transmission oil change
Spark Plugs
Throttle Body cleaning
Air Filter

My car, a 2006 Grand Cherokee, faced the same problem. I changed the transmission oil to no avail. The same problem remained when the car was running the transmission in position 3. The speedometer screen gave rise to heat in the transmission. I changed the car’s PCM computer. So far, no problem has occurred in my Grand Cherokee. 2006 in the transmission and there is no increase in the temperature of the transmission
I had the same issues with my 2006 Jeep Commander 5.7 Litre Hemi. Plus, my car would randomly shut off after cold starts. I replaced my module with a refurbished one from ebay. And its been running smooth ever since.
I know your comment is super old, I have a 4.7L and I’m wondering where you got the refurbished computer from?
All the lights on dash and transmission over temperature on my 2006 jeep grand Cherokee 5.7. I changed the TCM computer from eBay and no problems ever since
Got a new pcm seemed fine for the first day. Next day it had same issues. Was told to change the tcm. 2006 jeep grand Cherokee 4.7 l hemi 4wd
Thanks for this, my '06 just started doing the same thing the other day.
This is the first vid that seems helpful… only difference is my sentry key light is also on, and it won’t start or crank, idk y
You can open the module carefully and inspect it for damage. These Jeeps are known for ignition switch issues.
Thanks dad!
Hey, the dielectric grease is not for helping with electric current. I used to think the same thing but it does the opposite. It's great for putting on spark plug rubber though, not the metal parts. Great video!
Back in the day when I was a Jaguar Master Tech the engineers recommended putting dielectric greace on the connectors to prevent corrosion, which leads to high resistance in the circuit. I followed that added measure since I was living in Acapulco. There's a high chance of corrosion build up from the ocean.
@@christianlopezyourhelpfuld7079 I use it on the plastic connectors for easy removal. It's a non conductive grease. Basically like a silicone grease.
My daughter's 2006 Jeep Grand Cherokee 5.7L has had the same error code for quite some time. It only happens when it sits idling for an extended period, or on really hot summer days at stop lights. It switches into a sluggish mode when the "transmission over temp" light comes on and if you pull over and switch it off and back on, the light goes off and it drives normally. Several shops I took it to could never get the code to trigger or figure out what was causing it. Very frustrating! I'll look into replacing the PCM, thanks for the video Christian!
Did you change it and where did you buy it and how much? I'm having the same issue. 06' 5.7 trans over temp😢.
@@trinity21MA Unfortunately no I haven’t replaced it yet. They run about $500 to $600 bucks and I’m about to sell it because it’s an extra vehicle right now that I don’t need. It looks easy enough to replace myself but I don’t think it would be worth it on resale unless I’m keeping the Jeep. If I was going to keep it I’d be ordering it today because that issue is really annoying in the summertime. I’m too honest and will tell a prospective buyer about it and take something off the price for it if they want to fix it later. If not I’ll sell it to someone else that wants to deal with it. I really like the 5.7L motor, it’s got great power for that size SUV and I’ve never had any problems out of it except for that annoying PCN error. Best of luck, I hope you get it fixed!
Your module does not have the big aluminium heat exchanger on the back... That would explain the overheating... Look for more photos on internet.
I was getting that error message about the trans over temp when I replaced the ABS module. It wasn't communicating or it was doing it wrong. I think it was because I bent 2 pins inside the new mod. I got another new mod and it cleared up the code. Check for good connections before replacing the PCM next time. Now on to the limp mode that comes and goes and or seems to stay on.
The first mechanic I took it to replace the ABS module and had my Jeep apart. I told him that I'll look into repairing it myself. Replaced the PCM, and all my problems went away.
Im having the same problem my runs and thn i get thr transmission over temp i waiting for my pcm and tcm to arrived
Hola, tengo el problema en mi jeep comander 2006, al abruel el switch enciende una luz Roja en el tablero y cada vez que esa luz enciende al encender el carro a los pocos segundos se apaga, pero cuando abro el switch y esa luz roja no aparece, enciendo el carro y funcioba sin problemas, ya se cambio el ECM, y sigue el musmo problema.
Sera ECM defectuoso u algun corto eléctrico???
Puede ser un ECM defectuoso. Checa todos los grounds y las conexiones al starter.
Did you have to program the ECM or did they already have that done?
It is preprogrammed to your VIN. Make sure you contact them before you place the order.
@@christianlopezyourhelpfuld7079what about the key programming will you be able to use the same keys
@LiilTyweezy I was able to use the keys without additional programming.
Estimado. Adquirí una grand cherokee laredo 2005 3.7 gasolina, con check engine encendido, luz break, abs y parking encendida, luz de presión de neumáticos y además testigo antideslizante. Velocímetro no marca, cuenta kilometros tampoco y aquí viene lo grave, caja tip tronic no muestra ningun número en pantalla, como si estuviera desconectada, en direct es como si estuviera en una marcha y acelera sin parar, como si estuviera en limp mode o desprogramado. Hice scanner y sólo arroja como si fuera problema de transmisión, qué el abs esta defectuoso. Será módulo PCM?. Puedo conectar otra PCM y probar o requiero programar?. Muchas gracias!
Definitivamente verifique que el PCM no esté dañado y verifique todas las conexiones en busca de corrosión o alta resistencia.
Hola, tengo un jeep 2006 4.7 y ya le cambiaron la transmisión y sigue arrojando transmisión overheating.
Crees que se el mismo problema? Saludos y gracias.
Hector yo tengo un jeep 2006 5.7 y ya le cambie la transmission 2 veces igual me arroja transmission overtemp lo apago lo prendo y se le quita y el carro esta normal, otro caso es que en ocaciones despues de manejar unos 10 min apago el carro y lo enciendo de nuevo si prende pero alos 5 segundos se apaga solo esto ya no se me hizo normal lo lleve con un mecanico y me dijo que la computadora tiene bajo voltaje entonces mi conclusion es la computadora para mi jeep ,saludos
Si puede ser. la transmisión sobre la temperatura se encendía y luego se apagaba cuando apagaba el Jeep. El fluido no olía a quemado por lo que era una indicación de que mi transmisión estaba bien y yo tenía un problema eléctrico. Si su fluido de transmisión es bueno y la luz se enciende pero cambia bien. Compruebe el módulo PCM.
08 Jeep Laredo 3.7L 95k no crank, no start. Flashing trans over temp really quick when going to start engine but goes away. checked battery starter connection. all lights turn on and radio ac. Radio will turn off when turning the engine on. Everything else stays on. codes reader giving me u0100. witch is lost communication with ecm pcm changed ecm with eBay one. “programmed to vin” still flashing trans over temp. all lights turn on radio ac the radio will shut off when you try to start engine as before. only ground Is missing I can tell is the one that connects exhaust to trans case i think. was running without out before tho. Any tips would be highly appreciate and recommended!
I know this is old Christian but did u happen to get the Tcm programmed to your VIN? My guy is saying that even if I get a new TCM it still has to be reprogrammed to my VIN so it can recognize
The company I bought it from programmed it to my vin
Hello thanks for the video. Want to know if you had the limp mode as well where it was only in 3 . Not D on the PRNDL. Thanks so much
No limp mode. Sometimes, I was able to turn off the Jeep and on again to turn off that warning message.
Hello I have a question is what about your odometer do they recorrect with the new PCM or the current odomete stored in the electronic guage.
The odometer is stored in the cluster for this year.
hola amigo,,,, tengo una 2007 grand cherokee 4.7 yo tenia un misfire cilindro 8 le cambie bujias coils y no se le kitaba le cambie los cover gaskets de las tapas ke van arriba los dos lados los puse nuevos y se le kito el la luz check engine y el misfire desaparecio pero cuando solo abro la llave swich ) sin prender se keda la luz prendida y parpadeando pero no tiene ningun codigo y lo ke pasa es ke no acelera bien es problema de potencia cree ke sea la pcm....
gracias....
Es fácil a una inspection de el modulo antes de remplazar lo
Hello I have a question? Do you know how much is the computer?
It ran about $270 for my year and make
@@christianlopezyourhelpfuld7079ok thank you
Solve the problem, change the pcm
How do you know if you should change the pcm or the tcm
@@jaybrick8973 If you have a problem with the transmission in position 3, when you start the car or the car’s computer gives a warning signal about the high temperature of the transmission. When you change the transmission into position D, it does not work. The transmission is in position 3. The problem is with the car’s computer (PCM).
@@jaybrick8973 You must check the transmission fluid if the transmission fluid is good. The car computer gives a false warning signal regarding the transmission temperature rising when the car is running. Switching the transmission in position D does not work. It gives position 3. The problem is in the PCM.
Was your engine running rough before you replaced your module?
No. It's was running normal.
Hi! I replaced the PCM in my 06 jeep because it was turning off randomly. It no longer turns off but now I’m getting the same messages you had in the beginning of the video. Transmission over temp, abs, and so on. I’m getting a failure to communicate with tcm code. Do you suspect the tcm is bad or it’s not able to communicate with the new pcm? I also had the engine replaced a few years ago. The same mechanic is telling me to go the dealership and have the car reprogrammed but I don’t think that’s the issue…. Any thoughts? I’m feeling defeated lol
Yes, the new PCM could be faulty. If it has warranty I would request a new one. If not, check out where I bought mine. It's in the description. If you do get it warranty, take down the serial number so you don't get the same unit back
Jeeps are a piece of crap
Did you have to reprogram module
No. It’s preprogrammed
Is the trans actually overheating when this happens?
Hi, sorry the late reply, I don't know why I'm not notified of this message. No, the transmission was not overheating, and if I cycled the key on and off, the message would turn off. Know that, I suspected the module.
What’s the name of the module?
PCM or ECM both are used
What company did you buy the pcm from?
arestechnologies.com/
Did this ever get fixed? I’m having this problem
Yes, 100% fixed when I replaced the module.
@@christianlopezyourhelpfuld7079 what module? The pcm? I got that replaced but without a cover. I notice everyone has a cover over their pcm. This is the dealership repair too.
@karadanvers6136 Yes, the PCM. It should always have a cover since it's an electrical component. It should also have some type of warranty. I personally replaced several parts chasing this issue, but if the dealer replaced several parts for you in trying to find the issue, that is not your fault. You should only pay for the part that actually fixed the issue.
