Hello seems like there is many different style of tightening the band.

From gearbox expert: 5Nm 5 rounds back.

Guess I'm going with that if none tells otherwise.

Then oredered the solenoid(2-3)90eur, some taps to the solenoids 2eur, new filter and gaskets 50eur. Still need new fluid and wait for parts to come.

Hope it works with these things....

Brake Band is a part of this automatic transmission that is controlled by one solenoid and can be adjusted from the larger oilsump. If I have understood right Brake Bands job is to work like clutch works in manual.
 
Also just went to show this picture of the magnet to one expert of automatic transmissions. He said that if the magnet looks like hedgehod it might be bad... But he encourages me to change this one solenoid and see what happens

Parts coming maybe for next weekend...

I must admit, I have never seen that much swarf on an Omega sump magnet, even my latest with a failed thrust washer.

Well that isn't something nice to hear 

But I think this will be something that I need to test and try as this solenoid change is so much easier than taking the whole gearbox out...

And also I have planned to only use old gaskets and filter to save money if the box doesn't work with the new solenoid, new gaskets and filter can be fitted when box is confirmed as working.

[Muroman]

Hi,

New solenoid in, new filter, new oils. Did proper testing and it just wont change from 2 to 3...

With 1 and 2 gear it has grip and goes good but when trying to change to 3 it wont find it and when it finds it goes to safe mode or what it is called.... Never going to fourth.

This doesn't sound mechanical failure to me but Im out of options here....

Can anyone tell anything else or next thing to change box?

[iansoutham]

If I am not mistaken, Winter mode is 3rd gear?

What happens when you try doing this? Pure curiosity

Well didn't know so went to test and the car wouldn't move an inch....

What happens when it tries to change into 3rd gear?

Does it stay in 2nd then go into limp home or does it start slipping?

Starts slipping and when I lift off the gas pedal it hits the gear in. After that, depends cars speed and pressure on gaspedal it either goes to safe mode or starts slipping again.

Heads up...just in case you need parts for your transmission,rather than replacing the complete unit,then JPat will have what you need as they carry a comprehensive stock of parts for most transmissions.

Sounds to me like the clutch or band that selects that gear is worn. The solenoid's job is to initiate the gear change and that's clearly happening but once that gear is selected there's insufficient friction to transfer the drive.

I think a 2nd hand known good gearbox would be your best option, although it might be worth talking to an automatic transmission specialist to see what an overhaul would cost.

Yes....that makes sense. I will continue getting more information about the work on the box, there is many ways this could be done. I could even open the box myself, internet really has every info about the box but there is no simple way to tell whats wrong with it.

For now I bought a temporary car bmw e36   

[Muroman]

Hello,

Got another box now and doing some maintenance for it.... It worked well in donor car but still as it is in my carage I can easily access to different kind of spots there....

It clearly has been open for some reason, because in between turbine housing and the middle part of the box is some kind of goo.
Maybe thurstwasher has been changed? I'm not sure if I'm brave enough to find out

Well today started of by cleaning all the electric connections and also the switch.

Questions:

Tomorrow I'm going to open the oilsumps. Just wanted to make sure that there isn't any reason why I couldn't turn it upside down???
I also want to adjust the brake band so is safe to do as the box is upside down without anything bad happening??

And if I'm going on the thrust washer, facts about the end float of the inner shaft? 0.1-0.8mm? Where does it make difference? Safest go is 0.4mm?

-Mika

[Muroman]

Well done tightening the band as installed on car because none answered  It was 5,5 rounds open.

End float measured 0.8mm so I'm not going to open it up.

Only things need to be changed: oil pump seal (the one with three bolts) and o-ring on the shaft. Anyone has measurements of the o-ring??
