1.9 TDI 09B auto gearbox no reverse
« on: November 21, 2019, 03:17:50 AM »
Hello friends,

i read many threads about 09A gearboxs faults... maiority about the solenoids...

but i have some questions, if someone could help please..

the 09A solenoids are compatible or same with 09B ?

what is the diferences between 09A and 09B?

I had my 3 engine mounts changed at dealer, and after some days, i started to feel like slippage on 3rd or 4rd gear engagement (not sure which one)... but didnt take too serious, because it did only few times.... not all time....

and now, it started to fail reverse engagement at cold... is like we are at Neutral.
after few minutes, and few tries, it engages and runs nicely, like nothing happened...until next stop for some long minutes...

Dont have any fault registered on vagcom...

could be something have been damaged on the engine mounts intervention at dealer? or is just coincidence?

im ready to change all solenoids... but im looking for some more informations... because i just want to open the gearbox if im sure about what problem is...

Thanks!!

I'd start by assessing the state of the oil if you haven't already done so, both level of it, and what condition its in.

Most reliable way to tell on the solenoids is look at the parts list, if they have the same number, they are the same thing, if its different there will be some difference (could be as simple as the connector, may be something more critical).

Firstly I would say it is coincidence itís started after mount change.

Secondly the 09a and 09b share the same solenoids.

It sounds like you have a sticky solenoid to me so be wise to renew them. Personally I would replace solenoids and do a fluid change,as you canít get all fluid out I would run it for a few hundred miles and do another fluid change.

Yes, I'm looking to order new solenoids set (i think is better to change all 9...dont know if im doing right or not) and im going to do a oil change also.

(Only did once... And have around 160k miles... Is mine from new).

I have other question... What about the gasket? Silicone? Or can use the cork ones that is selling with the solenoid kits?

Do anyone knows tightening torques?

Never done one myself but from factory cover is silicone on so I would go the same route. Some megablack or megagrey would do the job nicely.

Torque Wise looks like M6 thread so would say about 10nm

thanks friend...

im going to try to do it myself...

so, im going to order the solenoid kit and the silicone...

The selonoid kit comes with cork gasket... but.... never seen it before... so, im going to use silicone.  :-[ :-[

there cant be some spring pin, or some leveler damaged?
if it was, it wouldnt work even when warm right?

I donít know if it is cable or electronically operated on that gearbox but the fact it engages drive and works apart from you get slip in 3rd and 4th suggests itís more internal to me.
If it was a cable/pin damaged or dislodged when they did mounts you would be noticing selection issues I would think.

Same with reverse if there was mechanical damage then it would fail to select all the time.

Makes sense...

Im going to order the solenoid set and try to change them :)

Hello friends,

I changed all the 9 solenoids, and let me tell that is a big project change them with transmission installed in the car...  [bash]

I had to remove coolant line from radiator, intake hose from intercooler, to have some room, and also got much difficult removing one screw from solenoid, that was going in IC direction... Was not easy, but done... and solved the reverse problem... i find 3 solenoids stuck in my box... the N93, N91 and N283...

My atf was a bit burned and dark...

All finished fine, is now reversing at cold... but now i have 2 new problems  :'(

1 - Cant read ATF temperature on VAG COM... i get error on that block... :(
I put ATF aproximately same quantity from what comes out... so, dont know if is 100% on level.

Can my ATF temp sensor be damaged?
Can be my VAGCOM version?
(dont have any fault on error memory)

2 - I feel that the car is no holding on uphill like in past... i only drive around 5miles yet...
Can be the neutral sensor position?

Thanks!!

Given the problems have started since solenoid change and you are not too sure the level is 100% correct I would start by getting level correct and testing again.  Of fault persists then I would suspect you have missed or damaged some wiring on the rebuild

The usual advice also when the ATF gets bad, is to change as much as you can of it, run it for a bit, then change as much as you can of the fluid again. This allows the new fluid to break up the old gunky stuff, You will never get all of it out without using a pump made for the job in one go. But checking the level would also be sensible at this point, you should find info on doing this on the knowledge base on this website.

Did it work before you did this? Your looking for it to be around 40 degrees. I'd try giving it a drive about (15-20 minutes should be ample) and then try checking it at that point.

You might be able to use a thermometer on the fluid if you can let some get in contact with it safely (if your thinking to put it into the box itself, only do that with the engine NOT running). Something like this is what I'm thinking

https://www.amazon.co.uk/TOPELEK-Kitchen-Thermometer-Multi-functional-Included/dp/B01GCEY2IS/

https://www.fordmpv.com/smf2/ford-galaxy-common-faults-and-problems/ford-galaxy-automatic-transmission-fluid-replacement-level-check-(ag5-09b)/msg7601/#msg7601

Alternatively drop some out of it into a container, which will allow you to inspect what state its now in once you've warmed it up as above, and check the temperature of it in the container. You can always put it back in the box afterwards before checking the level.

What version of VCDS are you using? I don't have an auto box on mine, so can't compare. Would suspect on a vehicle of this age, that its a faulty sensor rather than a VCDS issue though unless your using an ancient version of vagcom maybe. (your screenshots show VAG COM so maybe it could be the issue, what lead do you have is it compatible with newer versions?)

Hello friends,

Thanks for your suggestions and help.

The problem is my vagcom version or installation... Don't know.

Asked a friend to try with his vcds and other tool, and readed atf temperature without any problem.

Already ordered a new lead, compatible with vcds.

Drive today around 50miles, and all good for now.

Thanks for all.

Must be your VAGCOM version then, at least you know now. You might get the lead you have to work with VCDS lite. if its a legit lead (there are a number of clones on ebay of various leads which will only work with the software supplied with them) then it should work with the latest version of the software. VCDS lite should work with the basic leads, and for most functions will work ok. Some of the more in depth functions will not work, not sure the ATF temperature is one of those or not.
