01 Durango with 5 pin nss coming from harness the transmission has the 3 pin nss. Sonnex has adapter for the opposite scenario. School starts in less than a week and need to get truck going. Please any help will be appreciated.

 

NSS?

Go to the parts store, and by the 5 pin?

 

Neutral Safety Switch ....tried to buy a five pin and just screw it into the transmission wouldnt work didnt fit.

 

I just thought of something the transmission that is installed in the Durango I believe was from a Dakota would it make a difference in the 5 pin nss my husband ordered. He went off the Durango and not the vehicle the transmission was from when he ordered the connecter that didnt work. It couldn't be that easy?

 

Likely the same trans. The pin count changed over the years...... I don't have wiring diagrams to see what the additional wiring is for....

 

Sonnax doesn't have an adapter for the other way around because the PCM doesn't support going that direction. As you found out, the transmission case was changed for the new NSS after the communication buss change in 01. The 3 pin was with the CCD buss, 2000 and older.

6 pin Transmission Range Selector:

1. Brown/Light Green: Ignition Switched Power
2. White/Light Green: Transmission Range Output Mux Signal
3. Empty/Key
4. Violet/Black: Back Up Lamp Power Out
5. Dark Green/Gray: Transmission Range Sensor 5V Supply
6. Black/White: Park/Neutral Position Switch Sense

Basically, you have 12V going in (1), switched to the brake lights in reverse (4) or to the starter relay (6). Meanwhile there is a variable voltage source in the sensor which takes the 5V in (5), and emits various voltages which the PCM and cluster then decode to determine which gear position to display on the dash (2).

On the 3 pin, you have power in, power out to reverse lights (reverse position), and power to the starter relay (park/neutral). There is a mechanical gear indicator on the dash, so the PCM does not care to know what gear the shift lever is in at the transmission.

If you can live with never know what gear the transmission is in, you can make this work. I can tell you how, but the result will be that you'll be able to start the truck in gear. You might be able to get reverse lights out of the predicament but no guarantees. The connector you need access to is easy to get to.

More reliable option:
You might be able to splice the connectors across, 12V to 12V, starter relay to starter relay, and backup lts to backup lts. You'll probably get a christmas tree dash if it works at all, but it will get you running.

 

I can live without knowing what gear im in ....right now i can drive it but it doesn't seem to shift any higher than 2nd gear.
If you could please tell me how to do this ....im fine with it starting in gear need to make it work...thank u in advance

 

So how are you driving it if the NSS is unplugged, to know it won't go past second gear? The PCM shouldn't go into limp mode (I dont think) just for a missing mux signal, though there will certainly be a code or 3 for it missing.

There is a yellow wire behind the parking brake pedal, connected to a green electrical connector. Tap and ground that wire to defeat the neutral safety.

To properly splice the 5 to 3 and leave out the mux, i'm not exactly sure. I don't have an 00 and older FSM to compare pinout to.

 

I have 03 Dodge ram and can't get 5 pin NSS back in either, is there a trick to this... help, help

 

I think trans goes in low gear, you compress the plunger, stab it in there, then run the screw in.
