Hello,

Today morning was cold and kinda wet so box couldn't find gears and swapped to neutral in drive... hope it's the switch. What do you think?

Going to start with the gear selector switch as the oils and filter has been changed 30 000km ago.

I've read this topic http://www.omegaowners.com/forum/index.php?topic=90673.0 couple tens of times and I'm still not sure what the alignment really does?

I have looked those pictures of it and others too from the google and came to a conclusion that the switch cannot be put wrong in there?? No need for alignments?

Just don't touch the gear selector in the car while the switch is off and after putting the switch back together see that the hole is somehow on right position and when inserting it won't go on wrong position, am I right?

Do the indicator lights beside the selector lever agree with the gear you have selected?

Do all the lights come on together?

If  the lights behave normally then it probably isn't the switch. If they all come on together then you may have got water in the switch and it might get better if you take it apart and clean the contacts.

If you take a switch off then you will need to align it properly when you refit it.

Lights work properly all times.

What do you reckon then?

[Muroman]

Cleaning done and more experienced... Seems to go on first gear but after that its hard times to find more and eventually goes to some mode that forces second or third gear... What is happening to this well worked box 

What next? And big question can the whole box be changed without taking the engine out?

Are you able to read the codes for the gearbox ECU?

Faulty solenoids can cause similar gear selection problems.

Have a look at these two threads for a bit of background. There most be loads more on the forum but I didn't find them with a quick search.

Thursday I will get more answers as I get it up and also better code reader as the one I tried didn't connect to my car. I'll be back with results.

I don't remember the code anymore that came up but it was related to engine speed and gearbox speed. Probably caused because it went redline with speed of 10kmh....

But anyways they couldn't say what is wrong with the gearbox so I guess I'm going to open the sumps and see what's in there.

If metal scrap then its done, if plastic bits then it is the "washer"? Aaaand if there isn't anything I don't know what to do

Typical symptoms of a faulty solenoid if I recall correctly.....

[Muroman]

Okay so that might be the cause then if there isn't anything on sumps.

If gearbox off, Opel Tis says engine off??!? Is it possible to take it from under?

More pictures of the soleinds available?

Sump(s) and filter off and should be readily accessible

Sump(s) and filter off and should be readily accessible 

For the solenoids?

What if problem further up? Will it come down?

[Doctor Gollum]

Sump(s) and filter off and should be readily accessible 

For the solenoids? Yes, simply held in with screws/bolts... should be obvious once the sump's off

What if problem further up? Will it come down?

Can't be any more help though

search for guides to the 4L30E and you should find some helpful information.

I would post some links but it is difficult on a small screen.

[Muroman]

Done s***load of research and starting to really believe you andy...
This I don't know is good or bad but at least this project is going forward with somekind of knowledge.

Where is best to get solenoids from? E b ay is offering parts from USA and then there is my local money robber... know as original parts dealer

And thanks for you mates at this point, keep up helping me with my questions 

[Muroman]

Hello,

Found at least one broken solenoid, now just need someplace to order new ones....

Pictures you think too much metal on the magnet???


Dirty switch


The one with blue connector was broken or didn't "knock". Also if I would mix them how would i know which is which??


Working enviroment


Also band adjustment good to do as everything is open?? 4,5NM and 5 rounds back?
