2006 Dodge Dakota 4.7L TCM Issues

[@ryana9783]

How is there not a class action lawsuit regarding this issue? I have a 2006 Dakota 4.7 HO and spent a good deal of money chasing this issue with no luck. Don’t feel like I can sell it knowing the troubles it will give anyone else once summer rolls around.

[@david-tj4yq]

WOW! Best video for this issue I have ever seen. My 2005 Dodge Dakota is doing pretty much the same thing. Thank you so very much for the video!

[@IceBergGeo]

I've had almost the whole gamut of codes you've had, but it is currently very intermittent. Only in the summer though. It happened last summer, too. At least I know where I've got to go with it. I've done most of the tests you've done, but I don't have a nice scanner in order to deal with the programming and stuff. Thank you. Been looking for this video for a year or more.

[@mexicanic4976]

Have the same issue, mine is a lot more intermittent than yours. This one will run fine for the longest time, check engine light will come on and go on limp mode. Car is restarted, check engine light stays on but car runs fine. Been fighting it for 3 weeks now. Haven’t been able to catch it when it’s acting up to condemn the pcm. I will try the heat method to see if I can get it to fail. Very informative video.

[@rsaldivar4218]

Same Trans Temp Over error here. I’ve replaced the PCM, no change at all. I’ve heard that it’s a ground or power issue… and that a stronger Alternator and bigger ground wires can solve it?

[@7700jessie]

My wife's truck has this similar issue,.... 2006 Dodge Dakota 4.7. If you turn on the ignition then start it the transmission goes into "Limp" mode BUT if you go straight into starting it runs fine without any problems.

[@King_Of_The_Asylum]

[@7700jessie]

@@jake2772 kinda....... TIPM issues are still evident. As long as I just start the truck straight on instead from "Key on" position I have no issues.

[@braq331]

[@CatterlinRanch]

Great troubleshooting. My son’s truck has the same issue. The problem looks fairly common with these. Rather than swap in a salvaged PCM I’m trying to figure out if the PCM board can be repaired.

[@dennismusch1623]

had a problem with shifting, wont go into 3rd or 4th gear, at first thought the solenoid pack is bad. I checked the resistances on all the solenoids they seemed ok, I had a code 934 .. I suspected a bad wiring because of low voltage at pressure sender . ran another wire and proceeded to tear apart the harness tracing all wires and checking splices for corrosion. also disconnected the connector going to the solenoid pack, put everything back together and did a test run. everything worked fine after that , however the voltage reading at the pressure sender was only .15 volts, I suspected the temperature circuit may be bad as it runs in series with the oil pressure sender. Checked the resistance on the temp sender it was good 6.5k ohms then decided to replace the oil pressure sending unit with an OEM part.. this fixed the problem, no more 934 code and shifting is smooth in all gears.. sometimes things just don't add up.. shifting was a problem and fixed itself by cleaning all connectors and just pulling the harness bundle apart may have been a loose wire somewhere, but all wires were good, nothing broken ? ??

[@RobertVick-zp6wf]

What would have happened if you had done nothing and kept driving the truck? I am considering that.

[@jamesxfrost3520]

Fantastic video! The depth you go into is perfect. I wish I had a mechanic around here that has that much attention to detail.

[@alpinehs]

Wow!!! Great video. Helpful too. Thanks for sharing.

[@Ricky_1_Bobby]

I have a loss of power to my t case. What would be my solution? Can't afford a good mechanic. Been 3 years

[@siggyretburns7523]

So in short, the PCM modual is like a quack dr. It misdiagnoses everything else when in fact, its the problem? I kinda figured something was odd when it said left rear ashtray sensor has low pressure radio station. J/K, but it comes up with something different everytime

[@jaystrobel5258]

Great video and input. I have the same limp mode issues on my 06 dakota. Where were you able to get all the schematics from? I tried looking online and came across some different schematic configurations. It doesn't seem that I can just search for the right one on google. Is there a specific site? I also tried all parts with little help. Thanks again!

[@cactusstudiossouth]

HELLO! I've watched quite a few of your videos in trying to find an answer for the problem I have in my 2001 Dodge Dakota SLT crew cab four-door 3.9L engine! The truck always shifted a little funny, (after all it is a Dodge)! But last couple of months once it's warmed up and I start driving it trips a code, the P07020 Output Circut Code, Speedometer goes CrAzY and and stays in first gear! Prior to this I have, changed the Transmission Filter and Fluid. I changed the Governor Shift Solenoids. Changed the Vehicle Speed Sensor, (twice)! I reset the computer by disconnecting the battery cables, putting the two cables together overnight then connect the cables and drive it. As soon as it warms up it trips the code P07020, Speedo goes CrAzY and stays in first gear! I suspect I have a bad TCM however I wanted to know in my vehicle does the ECM power the transmission as well or there is indeed and dedicated Transmission Control Module and where is it on a Dodge Dakota? Best, JimiCactus   .

[@blautomotive7230]

@@cactusstudiossouth How many connectors does the ECM have 3 or 4?

[@loganbaize5134]

Could u just jump a wire from the batt to the 87 pin on the relay to make transmission work ?

[@mandy3480]

tried that and it did not work on mine.

Salvage yard PCM or new from Dodge?

@@CatterlinRanch I got one from salvage yard. Didnt work. Bought a new one, still does it. If it wasnt for the price of gas, Id be able to sell it.

[@siggyretburns7523]

It pisses me off. I have to stop, turn off the engine, turn it back on and go. Its not that big of a deal, but it always happens at the most inopportune time. The trans overheating thing pops up whenever it pleases too, even though its cool as a cucumber. I bought mine in an emergency. I'm wondering if I should have stayed with the emergency.

[@romerojohnson8135]

[@siggyretburns7523]

@@romerojohnson8135 I ended up buying a '77 Chevy Suburban so I could evade all the smog regulatory BS, but had no where to keep the Dakota while trying to sell it. It ended up getting towed from a supermarket parking lot. The lein sales place that towed it gave me an itemized list of all the towing fees and storage, etc. nearing $1000. Merry Christmas to the lein sales place. I hope they have as much pleasure as I did with it. 😁

We have po700 and po770 Feels like ours takes off from 2/3 gear Seems ok after get up and running but take off is bad

[@dagnabitification]

I pulled the relay in my 2006 today and pretty much had the same results as you did, it would work for a while when pulling it out then back in then there would be no power until you cycled the key. I took the truck for a drive and monitored the voltage and it would drop from from 14.5 to 13.8 every now and then, it was really quick and it may have even went to 0 and kicked back on, I don't know as I can only tell you what my eyes were seeing. The Trans temp light comes on intermediately and goes out within a few seconds to a minute and it only does it when its warm outside, its only gone into limp mode once about a year ago. I live in South Dakota and it does not happen in the cold months. I would like to see the video of the fix with the new TCM. Do you have a reliable source for getting a remanufactured unit? Great Video.

[@imbrbing]

I also have a 2006 Dodge Dakota 4.7 with the EXACT same problem, getting a new pcm. Tranny gets weird, tranny temp light comes on, pcm looses connection, restart the truck it goes back to normal. However I cant clear the pcm code so the money light is always on.

Let truck Worm up for 2 minutes or till rpm drops after start. Used seafoam 2 times. Works all of the sudden.

[@frannyeno]

I have an issue with a 4x4 2006 Dakota ST with a 4.7l. I replaced the transmission on it since the old one died and I've been getting codes P1603 and P0700. I believe it's a dead PCM. I got a replacement from a junkyard from a 2006 Dakota SLT, with the same model number. But the truck won't turn on when I swapped the new unit into it. What ODB scanning tool can calibrate this?

[@edcastillo532]

Mine has codes but it drives totally fine,it all happened after I change filter and oil on my transmission

[@Electric1892-n1f]

The TCM is in the PCM…. whole units needs replacing from what has been diagnosed here.

[@davidmunoz8798]

Why not slice the power to the relay to the tcm with a low amp fuse that goes to ignition power to test bad pcm tell customer that needs ecm/tcm and he will get a running vehicle for a wile till pcm gives out. Its not way to do it but u get paid ur hrs for diagnosing n customer gets vehicle running.

[@RobertVick-zp6wf]

Have a 2006 with same problem. One dodge dealer, 2 independents, and Cottman threw up their hands. Hendricks Dodge in Cary said replacing some valve, I think it was, would fix it. Then they said it needed a new tcm. Cottman had replaced it early. Hendrick said they programmed incorrectly. Now they say it needs a wiring harness which isn't manufactured anymore. They've had it 1 year now supposedly looking for a replacement. I'm $3000 in the hole and still at the starting gate. Stay away from these folks. They do not keep you informed, haven't heard from them in that year. I thought I'd wait them out, but not sure I can. It'll be interesting to see if it will even start now. Now, the short answer appears to be No, there isn't a fix. I hope somebody out there can point us in a new direction.

You think about how complicated the new automobiles have become. I found a 78 f150 with no motor but a very very solid body. I'm putting a 302 with old style points with low miles on it that I've already found. That's the way I'm going from now on and never looking back. Vintage trucks are very in now anyway . These new fangled automobiles with their high technology are the purest form of BS. I've ever seen. And only designed to shake the extra dollars from your pockets.
