Transmission issues or computer?

Asked by Sep 14, 2017 at 10:01 PM about the 2006 Dodge Dakota SLT Quad Cab 4WD

Question type: Maintenance & Repair

Every few weeks i get into my truck and shift it into reverse,
it slams into reverse and goes, then i pit it into drive and
ince again it shifts hard, then i step on the gas and my
RPM'S go up to about 2.5k and i slowly accelerate, then my
check engine comes on and when I get on the highway the
RPM'S shoot up to 3k and wont go down, almost as if its
still in 2nd or 3rd gear at 60MPH, I discovered that if I
remove a 20 amp fuse for the PCM the problem goes away
almost entirely (still clicks a little bit not a major problem) I
had to have my computer replaced twice so I need to know
what this is asap in case I need a 3rd computer. Because
it's a whole issue with ordering a new one and i really dont
want another one

I forgot to mention that when I remove the 20 amp fuse for the pcm I put it right back in and its not blown or anything its perfectly normal

Hey, did you ever get this resolved...? I'm having the EXACT same problem with my 2006 Dakota.

Add me to the exact same symptom list. 2006 with 73k miles. Anyone get it sorted?

I got a new computer again and it solved the problem until just recently where it happened all over again. Even with the new computer it still was shifting weird but i let it be. Just ordered yet another computer. still have no clue what is going on

Thanks so much for that! Looking around online with these symptoms and my heart just sank at what I am finding. Had no clue these trannies evidently notorious....sure cant afford a new one, and countless trips to a shop for trial and error has little appeal as well. Think I’ve read that the computer has to be programmed specifically to each vehicle? Or am I mistaken and it is plug and play? Thank you! J

The computer needs to be programmed to the vin of your truck. So yes it needs to be programmed specifically for each vehicle. The computer makes it seem as if the transmission is going because on these dakotas the ecm and pcm are one. Meaning that the computer controls the engine and transmission so when the computer fails it sends error codes out thinking the transmission is failing when its actually not. In my case about 13 codes pop up on my obd scanner.

Thanks again for the great help! It’s off to Dodge in the morning.
