Getting the Wheeling Fever

Frank, I'm cycling the OD OFF light in the instrument cluster by hitting the button on the shifter. Am I wrong in assuming that means the OD switch is working?


That should mean the switch is good.

The relay has 5 wires connected to it:

Black is full-time ground.

Blue/White is temperature switched ground and should show continuity to ground when the temperature switch closes (test wiring in between temp switch and relay by shunting the switch to ground at the thermostat housing).

Black/White is power to the OD/OFF solenoid valve on the transmission (check wiring by shunting temperature switch, IGN in RUN, transmission in D, OD switch ON.... should be power to solenoid valve).

Those 3 are the main OD control connections. There's also a Red and a Blue/red wire that go to the flasher and A/T temp circuits.

Ok Frank, I see all those wires coming out of the box, after screwing around for an hour got the darn screws out, and the relay box out where i can clean contacts etc. PITA. (as usual)..
then I pulled the plates on the bottom of the trk, found what I "think", "hope", 'pray' is the solenoid...what i'm looking at is drivers side of the tranny, sitting vertical on side of the case on top of a ledge which I presume is where the valve body is located. Before pulling that, I went chasing the wires. This "solenoid' has a black rubber cap and a heavily wrapped wire going in from the front at 90 degrees to solenoid body up on the top. Can't tell if its one or two going in there, chased it forward a bit and it joins another wrapped wire, goes to a tie and starts heading up over the bellhousing, where it is chopped clean off LOL.Looks like its been cut with a nipper, there are two wires, one pink or light red, the other black. Having a drink before I try to go find out where the other end of the 'chop' is. Please tell me I'm on the right wires and that I have indeed found the solenoid. I can't find a picture of the thing anywhere.

Yes, indeed - you've found the culprit.

Hey seer, I've got some Arkansaw jokes for ya'. State trooper stops an Arky and asks him if he has any ID. " 'bout whut?" the arky replies...(yeah, I know, you can substitute AL for AR pretty much in any of 'em...) [/quote]

Ok, Eddy, now you know darned well that only someone who is totally insensitive and hasn't been to Arkansas would tell a joke like that. If someone HAD been here, they'd tell this one:

"What do you say to compliment a pretty Arkansan girl?"
"Nice tooth"

Oh, and found something interesting, reason I couldn't see where the other end of the chopped wire disappeared to up and over the bell housing was cause it didn't go there. Appears to run forward up the side of the tranny, go through a tie, then reverse itself, jump over to the body and run back to a connector. Found the other end of the wire laying on top of the front driveshaft...duh.

Anyway, checked the black wire of the pair from that connector and sure as tootin, in drive, key on run, etc, when I hit the shifter OD switch, it cycles from 12v to 0v so soldering and armoring that pair back up, got a tore up blue/white pair on the other side to solder up and armor, and a brown pair going back to the rear of the transfer case that got munched before hitting two units that look something like sensors right across from the 02 sensor on the exhaust.

When I get that all done, I'll pull it off the ramp and see what we got smile

Good on ye for finding it, but I thought the od solenoid wire and a/t temp sensor wire climbed the bellhousing to a connector at the firewall...

If a man and woman are married in Arkansas and divorced in Kentucky, are they still brother and sister?

Ok, back from road test, tranny was shifting a little hard at first, but after a few miles shift points came down and ...drumroll...we have OD smile Thanks to all.

Now, unfortunately, got some vibration at 55mph...and it feels *funny* i.e. not like a tire or a sticking brake...sooooo, back up on jack stands this time, then into neutral and i start shaking and pushing on the wheels, all good, EXCEPT..when i went to check the ujoints on the driveshaft...turn it a bit, pretty good and tight, just a little play HOWEVER,,,after I turned it 3 or 4 times, it occurred to me that the shaft looked a little funny down at the other end...so i scootch on down there, grab the shaft, and feels like I've grabbed an egg LOL, *APPARENTLY* someone kissed a rock or some other hard non biological substance, with this shaft. LOL, pretty damned big dent.

Fortunately, I have a couple of shafts around here somewhere so I'll swap one in and see if that solves my vibration problem. Otherwise, truck is running very strong, not a hint of smoke, and even all the 4x4 & wheel lock lights are now operational smile oh, and changing the tranny, transfer and pumpkin oils tonight (already did the engine oil, and flushed the hydraulics while doing the new calipers and pads up front. But first, a beer LOL
