Yes the pan needs to come down next. Thanks for the wiring diagrams also. My stepson ( my creeper man ) and I got pretty excited we thought the gunk and dirt etc was the problem but it was not. I have a Mag Hytec pan with drain so it makes it a bit easier. I have changed the fluid and filter many times over the years but knees and hip makes this impossible now. Might be time for a new truck and let Dodge do the servicing. I can’t really expect stepson to change oil etc etc He has a job and kids. But I still have to repair it to sell it. I know we can change out the transducer and the solenoid but the valve body and inside wiring this where I have to draw the line on my skill level. You have to know your limits. It’s scheduled to go to the shop in 10 days. First shop would not work on it said they didn’t do electrical second shop truck was to old so we shall see with three. Is there really any point in thinking this is a transducer or solenoid problem at this point. I got 33.3 ohms on pin 21 on the pcm which is good. Hard to figure out how the wiring shorted out on the inside in my mind. More later and thanks to all for the help.

Ok we unplugged the big plug on the driver side 8 wire square with round center. Very dirty but not broken. Cleaned it up as good as possible. Left it unplugged new 10 amp fuse key on. Fuse did not blow. Plug it back in key on fuse blew. Picture using round mirror So what’s next? Drop the pan and change the transducer and solenoid I would suppose. Is there anyway to access the part of the plug inside the tranny? IMG_9630.HEIC.heif IMG_9627.HEIC.heif So what’s next? Drop the pan and change the transducer and solenoid I would suppose.

I ordered a 12445bk repair kit harnes (solenoid) 47 Re. It’s the plug and wires to splice on the end. I’m hoping the connector is bad. Or maybe just very oily and dirty ?

Thanks gents. Wire test tomorrow and clean the connector etc and inspect. Will report back ASAP.

Thanks for the reply I just reviewed the wiring diagram. 71 yrs old and hip replacement and both knees makes my under truck creeper days over. Finding it very hard to find a transmission shop that will look at this problem. This week end I plan on having my step son unplug the wiring from the transmission give it a good cleaning and inspection the try the key on and see if the fuse blows . At this time we will try to ohm out the wires best we can. I guess through the relay terminal but I’m not sure about this . I can’t drain and drop the pan yet. I have a May 28 th schedule with another transmission shop This will be number 3 and they are all backed up on their work employee shortages etc who knows. The pandemic has effected much of this. If the shop won’t can’t work on it stepson will drain and drop the pan and and replace the gov pressure solenoid and transducer . New filter gasket and fluid and I might be good to go if the wirings not bad. I have changed all these parts years ago etc it’s not hard but messy a bit . Anyway back to the wiring .can I buy new wiring for this truck? Or is it a find the shorted burned up wiring cut it out type thing etc. Has anybody found a replacement wiring and just changed it out. And how hard was that? That’s where I’m at right now thanks for any help . Is this what I need to repair the transmission end? https://cobratransmission.com/repair-kit-harness-solenoid-a618-47rh-47re-48re-205069-1 Is this what I need to repair the transmission end? https://cobratransmission.com/repair-kit-harness-solenoid-a618-47rh-47re-48re-205069-1 I would think it would be the end that comes out of the firewall to the transmission that would be bad. Most likely the connector. Maybe just oily and dirty and shorting out ??

Okay. Help me please. My 10 amp fuse was blown when I checked out my truck. My question is does a governor pressure solenoid or transducer gone bad can it blow the fuse or is it the wiring. Will the fuse blow if they are bad. No truck. Lifes not good thanks

1999 dodge Cummins 2500 truck has 168k with a DDT tranny installed about 120k miles ago . It has a smart controller installed to keep the torque converter locked up for the BD exhaust brake to slow me down while hauling my slide in camper . Third / forth gear lockup at 50 mph kicks out at 30 mph. 275 hp Rv injectors and edge set on high about 300 hp. Tranny built for this much horsepower. This my set up. 10 amp fuse in PDF blows when key is turned on. Has code p0753. Relay is good horn test. And pin 21 on the PCM READS 33.3 OHMS. Pan has not been down yet. I need good advice on what to do next ?
