I have a 2006 Dodge Ram 2500 5.9 (AT) Diesel. At this time I am having an issue with the Transmission not shifting. Also the Dash indicator, Govenor Solenoid and OD/Tow-Haul indicator do not have power. I have sent my ECM/PCM out for testing to ensure it works and it came back fine. I can shift on the column like a three speed.

If anyone knows where I should start please let me know? Any help will be appreciated!

 

Have you checked all of your fuses?

You sent the computer out that is bolted to the firewall on the passenger side, right? Not the one bolted to the side of the motor.

I suppose it could be a TIPM problem too.

How did you determine the gov pressure solenoid doesn't have power?

 

Checked all fuses. Had the truck at the tranny shop and at dodge. Guy at dodge thought the computer was bad. The trans shop looked at it said he thinks the trans is fine but there was no power goin back. He thinks I have a broken wire or some type of electrical problem. Just don't no where to start

 

What computer on the passenger side are you talking about. I only have the one on the block

 

You don't have a computer on the passenger's side of the firewall? White looking box in this picture next to the receiver dryer, top left?

Granted that's a 12-valve, but my 08 6.7 had a TCM up in that same spot too. Maybe 06/07 are different.

 

No just the dryer and coolant reservoir

 

Too funny. Older ones and newer ones have computers up on the firewall for the transmission.
