See this picture from earlier in the thread?

2000 model 4x4 wiring

Look at Gem module wiring

Pin 22, circuit 463, is Neutral input from DTRS.....Neutral SW IN........ Connector 223.....the 22 pin connector
you need to connect your digital transmission range sensor, pin 8 Red/wht (DTRS side of transmission Chevy guys call this the Neutral Safety Switch) to your Gem module and then you will have low range shift

C115 is the large 42 pin connector on your firewall all 96+ RBV have this

C282 is one of the connectors at the Gem module
Should be the same on all Rangers with gem module 98+?

Do you still have your V6 wiring harness?
What we are to do it unpin the neutral safety from your Rangers transmission to C115, and pin it in place in the 5.0 harness from trans to plug C115
Also check on the Ranger that this wire does indeed connect to the Gem module (continuity)

I can look up some wiring diagrams and trace this out I have a 2000 model wiring book downstairs.....
If you could that would be a huge help to me ( you've been a huge help already, thank you for that)

OK Mine don't look like that. Mine look more like C110, I have the same plug on a 98 ranger, 3 X 2000 rangers, 99 expo and a 97 mountaineer. All square and identical to this:

I guess I don't really understand how that connector plays into this. Basically I just ran the wire from the range sensor straight to the GEM

Yes mine is C110 and yours is also. 3 X 2000's like that, one born with 2.5 one born with 3.0 one born with 4.0 yours has to be the same.

okay try putting that wire to ground right from the gem module to ground just for testing
(you also have to be stopped and foot on the brake)

Something is fishy it should work!

The way the 42 pin connector (or C115 as I know it just like the pic Jamman posted) ties into this is, all the wires from the drivetrain/transmission go through there and to the truck, on the 5.0 side the wire is missing because they never had 4wd so why add a NSS wire

Look at C115 connector, pin 33 is the 463 circuit red/white , on v6 4wd models its there, on 5.0 explorers it is not
This 463 red/wh wire can go to more places then just the Gem so I would not cut it, but splice into it
Basically what was done is a wire was run from the transmission range sensor to the GEM.

Is the wire supposed to be integrated into that 42 pin connector somehow? Or is it just supposed to go straight from the GEM to the range sensor?

This is the neutral safety feed, it can go to a few different places on the truck side of things like the 4x4 shift control module, the clutch switch bypass and the cruise control

I think you did good by going straight from the DTRS to the Gem, not sure why you are still not getting a low range shift...maybe your motor is fubar now? Maybe we blew a fuse?

For testing you can try running it straight to a good ground near the gem...it looks like all the DTRS does is ground the wire when in N

Here is what I would do:
Run wire from DTRS to the 42 pin connector on the 5.0 side
You should find pin 33 blank on the 5.0 side
Make sure the 463 red wh wire is there on the truck side (pin 33)
Check continuity between the 42 pin connector (pin 33) to the GEM and make sure its the connected
Hook it up
That SHOULD allow the low range shift, at least it is for Brett.

Maybe his works because it's an explorer? And mines a Ranger?

That is a good question
My first answer is no it should not matter, also Brett is VERY good at these things and I told him your truck is ranger

lets check ..........Okay but the 42 pin connector does not change on these trucks, meaning they are pretty much universal the circuits stay on the same pins
Your truck was 2000 3.0L 4x4 automatic, it should have this wire

Do you have a red/white wire on pin 33 of your 42 pin connector under the hood?

tie into it there AND make sure you have continuity from that wire to your Gem
I am not sure why but Brett said to make sure your Ranger has continuity between the C115 pin 33 and GEM at pin 22 red/wh circuit 463
I am SURE he has his reasons
By adding this wire on the 5.0 side you are completing the circuit to the DTRS and the truck should again think it is a V6, automatic 4x4
It should fix the low shift

Hang in there I battled the ESOF in my 97 F350 for about two weeks almost daily before I finally fixed it, was a broken wire........

Otherwise its either getting a cobbled together manual case or it's getting sold..

I'm gonna try what you suggested instead of running the wire straight to the GEM. We will see what happens

Just checked, I do have a red/white wire on the ranger side of the 42-pin harness, pin 33. The explorer side does not have a wire in pin 33

add the wire from trans to pin 33, then make sure its connected to your Gem. Check your fuses and lets see if the Low shift is fixed!
Might not hurt to see the signal from the DTRS, meaning check that the new wire gets grounded when you switch the trans into N
fingers crossed

It should already be connected to the GEM, should it not?

I guess i'm just confused as to how running this wire to that connector will fix it if running it straight to the GEM didn't. Does that red/white wire go somewhere else?
