Hello, I have a discovery 2 2003 autobox. after having troubles with the M and S lights I finally found what Was causing it. It seemed to be a bad mv3 solenoid. So I ordered a good working second hand valve block with all the solenoids on. I thought it was smart to change the complete valve instead of just the solenoid so that’s what I did. I fitted everything back together and did all new tranny oil as the manual said (filter was done 3 weeks ago). I wanted to put it in reverse after all of that and reverse didn’t work. Drive seemed to work but in neutral, 3th gear manual and 2th gear manual the car drove forward like it was all in first gear. Now the interesting thing is that I could not get the lever in 1th manual gear. So today I decided to put my original valve block in it again but just swap the solenoid on it. So after everything fitting back together and putting again fresh oil in it the right way. The car doesn’t move anymore. It doesn’t move in drive, neutral, reverse, 3th,2th and 1th. The weird thing is that we can’t get the lever in Park (P) but we can get it in 1th gear now. Anyone have experience with this or maybe has an idea ? Thanks in advance!
 
I'm sorry to hear about your saga but i'm sure that you missed something there cos your initial problem was definitely the MV3 solenoid so something happenned on removal or refit of the valve block, i have no ideea what cos i'm no mechanic and i hope someone can help ...
though, as you did it twice how did you follow this step ?
.....
4. Align valve body to gearbox, ensure manual
valve is correctly located.

....
what do they mean by that ?
 
ensure selector lever quadrant engages with selector valve,tighten the valve block securing screws so that block can still slide then move in all directions against the screws and set it in the middle then tighten screws, there is a setting tool that gives the selector valve to selector cam the correct setting but setting block central is more than sufficient, then adjust the cable to selector lever on side of the box so all gears etc are selected fully

I have actually no idea... I don’t realy think there is a way to align them because the wholes for the bolts that keep the valve body to the tranny are already there, I don’t think you can even misplace it because all you can do is put the bolts thru the valve block and in to the wholes they belong in on the tranny... so I have no clue what they mean with aligning it unless they mean something else with the manual valve. I don’t even know what the manual valve is.

read my above post apart from ensuring selector valve fully locates on cam there is movement in the bolt holes

unless they mean the manual valve is the black thing next to the xyz switch but internal in the tranny but I don’t know how to align that if that should be the manual valve..

That was my point, unfortunately this is not a DIY job if you dont have some experience in that area, try to follow what @jamesmartin told you if you see what he means(i have no clue), i found this

Ensure the manual selector shaft is correctly orientated and sitting in the groove in the channel plate before you continue

Hi @jamesmartin thanks for helping out! So if I understand it correctly all I need to do different now is almost thighten all the bolts but still a little loose for movement of the block and kind of find the middle of the bolts and then tighten them? And then if I can’t get my selecter lever in a gear I need to adjust the cable so it can get in al of them ? Do i do all of this in park or in neutral ?

yes but ensure the selector valve is fully engaged in the selector cam first, the holes are slightly larger to enable fine tuning

Okey so I am not the best in the English language but the selector valve is the black thing right ? How do I fully engage it in the selector cam ? Or is it the picture sierrafery showed a couple posts ago ? Make sure it is correctly in its rail ? And is it possible to fine tune it while contact is on and someone in the car shifts to all gears to make sure the dash sees all of them ? Or am I wrong here ?

yes thats the valve in sf picture and the selector cam is in your pic
then fit the bolts adjust the valve block tighten bolts
then set the cable so it selects p fully ie p on stick in cab and p on box lever with which the box lever will be fully forward you can feel it click in to each gear then go through gears and ensure vbox is clicking into each
if you set the valve block centrally you shouldnt need to fine tune it and you cant really without the setting tool

Okey so just to be sure, I am sorry to repeat everything a thousand times but I am not completely sure what you mean. so first things first, we take off our valve block, then we see the black selector cam. How do I attach or allign or make sure the selector cam and the manual valve are in right position ? I have 2 pics one is the selector cam and the other (point 9) is the manual valve. Do I have to push the manual valve out of the valve block until it touches the selector cam or what do I do ?

you just locate them together as you fit the block,fit the screws the adjust the block so its central to the screws

Oooh okey so I think I finally get it now! My brother and I managed to figure out what you meant all the time! so in the pictures you will see orange circles those 2 things will fit together and that’s where our problem is now probably ?
