I just bought a 2001 SLT 2WD 5.9 Durango for cheap cheap because it is experiencing tranny issues and CTM electrical problems that the PO didnt want to deal with.
I know this issue Im having is very common on these 46re Durangos/Rams/Dakotas, so I could use some guidance in solving it, thank you in advance!
My particular problem is the tranny only goes into 3rd when put in D. I believe it's called limp mode. You can manually shift down to 2nd, but no matter what you do it will not go into 1st or 4th, period. If you put it into drive, it goes straight to 3rd and stays there, no downshift to 2nd when you floor it. You can manually put the lever down into 2nd, and it will go into 2nd, and 2nd is where it will stay no matter what. You can put it back into D and it goes to 3rd. That is all you can do for forward gears. Reverse works fine.
I have read numerous posts about the governor/transducer, OD solenoid, output speed sensor, corroded connections, bad grounds, and frayed/shorted wires etc etc. I just dont know where to begin.
This Durango is very nice, smooth running 360, good interior, and I bought it for next to nothing so I dont mind putting some $ into the trans to make it trouble-free and reliable. Is there a standard combination of new solenoids/connectors/relays/harnesses/wires that can be put in all at once to eliminate all the common problems at once?
Here are the codes I pulled today:
P0753 A/T 3-4 Solenoid/Transmission Relay Circuit Failure
P0743 A/T Torque Converter Clutch Solenoid Circuit Failure
P0720 A/T Output Speed Sensor - Low output Above 15 MPH
P1764 A/T Governor Pressure Sensor Signal Too Low
P1765 A/T Transmission Relay Circuit Malfunction
Where should I start?

A good close look at the wiring harness would be a start. I'd toss in a known good tcm relay too.
Do you have a scanner that can read data or just codes?

hi
1 erase codes and drive !
2 if codes reapear pull pan and look at fluid condition
adjust bands new filter see how much dirt is on magnet ?
may need solinoid kit replaced if trany is fairly clean
lots of dirt means most likely needs rebuilt ! Good advice. I'm buying a Ram Van (2001) today with same issue. Owner said scan showed solenoid problems. Trans fluid smells burnt and is black so I'm going to drop the pan, adjust bands and change fluid-filter, got my fingers crossed this works.

Circuit failures are just that - electrical faults. They may cause a trans failure but not the other way around. There is a main harness on the outside on RE and a harness inside that handles governor pressure, OD and lockup. On the RH there is almost the same internal harness for OD and lockup but the governor is like the old 727, no governor solenoid or transducer. Dropping the pan and seeing burnt fluid and expecting to resurrect the unit by adjusting the bands and changing the fluid and filter is expecting a lot. You may get lucky - for a short while.

*Edit* IGNORE THIS FOR THE TIME BEING^^^^^^^^^^^^^^We'll overhaul it when it's ready to be overhauled. Adam, find anything with a wire connected to the trans and unplug, blow out with a can of electrical cleaner and plug 'em all back in again. Unhook the battery for an hour and connect it back up and go for a drive. What's the speedo needle doing? Is it bouncing/taking awhile to register, or is it normal? Start with the easy stuff first, I wanna know what that output speed sensor code is doing on there.............

RWD RE units default to third gear. 41TE and 42LE default to second gear.

Or you can do like I did on my '00 Durango 5.9 and convert it to a 5 spd. Tim

One day, (it'll take a Brain Surgeon) I hope someone will figure a way to run a 545rfe behind a Magnum. By the way, what did you use for a flywheel on the 5.9 to do the swap?

You can run the NAG1 too, contact Sound German Automotive for the stand alone controller. This is news to me. Could the Sound German Automotive stand alone controller also be used on an earlier OBD-I 1995 vehicle like to replace a 46RH with a WA580 auto trans? https://www.allpar.com/mopar/transmissions/NAG1-WA580.htmlReplacing a 46RH with 3.21 ratio diff With a WA580 with 2.76 diff certainly seems to be an upgrade Since torque capacity is 420+ ft-lbs First gear crawl speed would also be superior.

360, Yes, you can use the NAG1 even behind a LA small block. Your old trans set up would not be used, Sound German would be able to tell you what you need better than I could. I just talked to them before about putting behind my 71 318. I went with a 42RH instead as it was a lot cheaper at the time. The controller is a little pricey (about 1200) but if you get the trans cheap enough it may be worth it compared to a complete rebuild of a 46RH. Plus the gearing is a huge improvement. You are exactly right about the gearing. Send them an email and they will get the info you need. There is a whole LOT more to it than just a controller. Basicly a total rehab of the car to fit, then the problem of the output flange, speed censers, converter options, the list goes on and on. There are better options out there.
