Hi All,
Does anyone know what the wire colors are for the OD and the lock-up on a 46RH in a '95 Dakota? How about where they are located.
Thanks
JD

If it is the EMCC solenoid on the tranny you're speaking of, the wires are black, dark blue, and light green. That's from the 1993 FSM. Should be the same on yours.

Thanks for the response. Do you know which wire controls the electronic lock-up and where the wiring harness is on the tranny?
Thanks,
JD

The black wire runs from slot 54 on the computer to the EMCC solenoid in the tranny. The dark blue wire splices into the ignition start/run wire. The light green wire wire runs to slot 55 in computer, and handles the tranny OD lockout solenoid. The black wire is the wire that the computer uses to send power to allow overdrive, then converter lockup. This particular connector is attached to the valve body, and sticks up through the case. So, to locate it, find the tranny pan, towards the rear, on the driver side, on the upper side of the case, the connector will be sticking up with a 3-wire on it. The tranny part of the connector is a white plastic connector.....but you won't see that till you pop the wiring connector off.

Thanks for the info! Is there anyway to disable just the lockup solenoid? This tranny is shifting in and out of lockup while on the highway with or without OD engaged. I was hoping that I could just disconnect a wire to disable it. Laying under the truck with my head towards the front and my feet towards the back and looking up at the tranny, which solenoid is it that controls the lock up?
Thanks,
JD

Okay, well now. You know the 3-pronged connector (white, oval-shaped) sticking up on the driver side of the tranny? Well that connector has a pair of wires to connect to the solenoid on the inside (on passenger side). The wires run along the bottom of the valve body. If you pull the tranny pan, you can see this. Now, the solenoids are paired, with the black wire powering the overdrive solenoid, and the white wire powering the lockup solenoid. I'm not seeing anything saying operation will otherwise be affected, but if you're getting lockup in any gear other than 4th, you most likely have a faulty lockup solenoid, in that it is not venting (not venting causes lockup). So, cutting the power will not necessarily help (it probably will stop lockup, but no promises--I say this because it should only get power when in OD, but if you're locking up in other gears, it must be getting power to close the vent somehow, probably an electrical short), since it looks like it's already fried somehow. You really should get it checked before clipping wires.

That was exactly what I needed to know. I believe that I have an electrical short somewhere, but my first test will be to disconnect (not cut, never cut) the lock-up solenoid. If I don't want to pull the pan, which color external wire does this white wire connect to? Also, does lockup occur with a 12 volt signal, or the removal of the 12 volt signal (i.e. pulled to ground).
Thanks Bunches!!!

Super-Bee, are you referring to my entry regarding the RamCharger? The reason I'm asking, is because, for some reason, that entry isn't showing up in this thread. It was posted last night, along with some further answers to JD's question.

Okay, now that's showing, but not the RC one. In short, JD, no, you can't cut the lockup from outside the pan. The power for the OD and lockup solenoids is carried on the same wire, and is only split into the two wires on the inside.

Of Course it is....what was I thinking. Why would Dodge have made this easy for me....
I have been thinking about what is happening and like you said, cutting the power to the solenoid may not do anything. It is probably good to take a look at it anyway. Maybe I will see what is wrong with it....
Do I have to pull the valve body off to remove the solenoid? What would happen if I just removed the solenoid and let it always vent?
Thanks Bunches!

Well, it'd be pretty tight to remove the solenoid without pulling the valve body, but again, the OD and lockup solenoid are mounted on a single frame which bolts to the valve body. Either solenoid cannot be removed individually. They are, in fact, sold and replaced as a pair. Think "Siamese Twins". So, you're limited to cutting the power supply to the lockup solenoid. This should allow it to remain in "vent" mode and not allow lockup.

OK, I went in and removed the connection (white wire) to the Lockup Solenoid. It looks like both solenoids have a common power (red wire) and that the white and black wires just pull them to ground? Anyway, I put it all back together and went for a drive. So far, it hasn't done the RPM jumps. It goes into OD fine and that is it, it doesn' try and make lock-up....so I have done what I wanted, now lets see if the problem is gone.
Yeah, it doesn't look like removing the solenoid was possible....
Thanks for all of your help!

Thanks all who replied (gen1dak) I have not had any problems with it since disconnecting the solenoid wire (knocking on wood). I think that that wire must have an intermittant to ground.
Thanks,
JD
