Help - Vehicle will not move - enter some deep water

[kashdaddy]

Discovery V8i, Auto

I went off-road this past weekend and went off the trail twice because of the rain. I ended up in a ditch the 2nd time where the water-line was about 3 feet high (had to get a trailer to pull me out). I happened to make my way out of the trail after about six hours of driving (thank god) and parked it last night. The vehicle will not move this morning when i tried to start it and put it in drive. The vehicle will start, but it fail to move when I place it into drive.

Could it be possible that some parts may be wet?
Could it be possible that the vehicle may have ingested some water?
Could it be possible that the axle or something in the hub may have slipped and caused the vehicle to not move?
Could it be a transmission problem?

Can someone please guide me so that i can have a mechanic check it out?

Check your transmition oil and look for a pink milk shake look of the oil, if this is the case, you got water in it. Your transmition is busted.

After a water crossing always check oil in the differentials, transfer case and transmition. If oil is in any of these parts its Ok as long as you don´t run them afterwards.

Is your handbrake stuck on? theyt seize in wet or shoes stick to drum

[kashdaddy]

I checked the tranny oil and it's normal.

The differential oil has been changed just before the trip and replaced with 90 Gear Oil. Could this be the problem as it may have been the wrong oil?

Someone stated that the axle or whatever is in the axle may have been tripped and need resetting.

Brakes are not stuck either!

Any other suggestions?

Strange one this, I take it no drive in any gear? when you move the gear selector does it feel right, does it feel like it's going into gear?
I would check the auto box oil level and make sure it's oil thats in there.

[kashdaddy]

Correct - the vehicle will not move in any gear including reverse.

The gear lever moves into the selected gear, but i am not sure if it's engaging in gear. Also, if i turn off the engine and try to remove the key then it seems like if the vehicle is still in gear since the keys will not come out of the ignition. But the vehicle will not roll if I push it unless it's in neutral.

There is fluid in the transmission.

Could the axle be slipped or some gear in the axle be slipped?

How is the geat lever conected to the box???

Ie cable to activate selected gaer, rods with a split pin through them?????

Is it work checking these if indeed it has either??


Cheers

I know this may sound silly but is the high/low range gear lever engaged ie in low or high box, just a thought, it's a strange one this.

It seems as if the high/low lever is having a problem engaging. I have two different mechanics checked it out and they both said that it's either a connection problem to the auto box or the auto box itself.

I will keep you guys posted on the problem, but the mechanic will not be able to get to it until tuesday.

Any other suggestions are welcome!

[graham]

Hope you get it sorted let me know what it was.

Does sound like something is not engaging.

If its a Discovery II then its possible that the XYZ switch on the side of the gearbox is full of water and corrupting the switch info to the autobox Ecu.If this is the case then the box will not engage gears - hence no drive.
The switch is on the side of the gearbox behind the selector arm.

VERY GOOD respond. You may be correct. I spoke with a Land Rover specialist and he said the same thing. He said that the ditch that I was in can cause this problem especially since the mud has dried onto it.
Do you have more information on this switch? Is it really called the XYZ switch. Where exactly is the switch located?

[Jon v8]

Yes it really is called the XYZ switch,its on the LH side of the box behind the lever on the side of the box that the shift cable ataches to.There is data in the Rave Cd that gives pinout and connection data.Bernie,perhaps you could post the pages ? I have to go to work now.(plus I dont know how to do it ! )
The switch is a riveted together assembly,but it is possible to drill them out and dismantle the switch.Then its up to you to decide how to bolt or rivet it back together.

I agree, a picture would be nice. Anyone care to share with us :)

[kashdaddy]

Also, if anyone has a part number then that would be very helpful.

These any good JON?

[Jon v8]

Thanks Chris,thats the ones - from them he should be able to work out if the XYZ switch is giving the correct outputs.I'm not too good with computers,I'm a bit more hands on with the spanners.(Finished off tonight Tig welding a cracked alloy clutch cover for a 2006 KX250 motocrosser,so he can race it on Saturday.) I've worked harder and got more jobs done in the last 2 weeks than I've done in several years,looking forward to a nice 4 day rest with my wife and the kids.

Found this on another site if it helps:

At the risk of jinxing my good fortune I can report that it was the
selector position switch that caused the problem. Once I got home to
my tools and was able to look it up in my shop manual I found that the
selector position switch (also called an XYZ switch) could be adjusted
on the transmission selector shaft a few degrees by loosening the two
bolts that hold it in position and rotating it on the shaft to a
position where the indicator lights and LCD work properly. I then
tightened the hold-down bolts and tried it out on the road. It's a lot
like how we used to adjust ignition timing by loosening the distributor
hold down bolt, rotating the distributor guided by a timing light, then
retightening. This took some trial and error because I didn't have the
Land Rover alignment tool made for the job, but following my second
attempt it has worked perfectly for 4 days now.

The hold-downs take a 10mm socket, and I found that a smaller, 1/4 inch
drive ratchet was easier to use in the tight, cramped space. To remove
the switch completely you also need a 13mm socket or wrench to remove
the selector lever before sliding the XYZ switch off of the shaft.
Once that is done I recommend unclipping the multiplug from its clip
where it's mounted to the side of the transmission before trying to
unplug it. I have pretty small hands but the space is just too tight
to work in otherwise. Lood for and press down on a little plastic
lever on the side of the plug and it will slip right off of the
mounting clip.

Thanks for the input. I think the person below was experiencing a problem where he was getting a gear, but the selector lever was selecting the incorrect gear. Example: When his lever was in Drive then he was getting Reverse or when his lever was in reverse he was getting Park, etc. However in my case, I am not getting ANY gear.

I think these diagrams refer to the Discovery II not the Type I as in my case.

Here is an update on the situation:

[kashdaddy]

Ok, the mechanic replaced the transmission park gear and put everything back together. The problem now is that the vehicle will not start. Battery is good and no other part was touched. Does anyone have any clue what might be causing this problem?

[grieuclarke]

Just a thought here, if the selector or Gearbox thinks that any gear other than Park or Neutral are selected the engine won't start.

[kashdaddy]

You are correct, i will have the mechanic double check for fitment centered in/around the selection of gears. Any other suggestions are welcome. Thanks!
