Stuck in park after changing mechatronic sleeve and seals

When changing fluid and filter I attempted to change all the 5 seals between the mechatronics and trans. After adding fluid until it ran out I attempted to start vehicle and run it through the gears. Transmission now will not go into any gear. When attempting to put it in R,N or drive it automatically goes back into park. I did make sure the park lever which was wire tied into position was back in the park lever. Any idea what the issue could be?

One more thing. I attempted to start vehicle before plugging mechatronic back in. Don't know if that can cause the problem.

make sure sealing sleeve is properly fitted. from what i've read your supposed to use vaseline or some type of lube on the adapter.
did you reset adaptations?

did you do the fluid procedure correctly? there could be many things. Hopefully it's not big ! goodluck

Smile Fixed

Last filter change I did the trans took 4 liters initially and after topping off took almost 2 more. This time after dropping the valve body to change the mechatronic sealing kit it took 6 liters initially and I had to top it off after shifting through the gears for a total of 8 liters.

What happened: When I went to drain the fluid again to recheck mechatronic install no fluid came out. Went through the fill procedure and its a done deal. Car shifts like new. What I learned is there is some sort of sensor that senses trans fluid level. If the level is not at a certain point the trans will not shift into gear.

Thanks for the ideas

Was it easy? A Bmw tech wants 150 + parts for the job. The car is in my garage and I can put it on jacks.

Is it worth paying 150 or should I tackle this myself?

It depends. Is he changing the four sealing sleeves (http://www.thectsc.com/products/seal...32-214-50.html), bridge adapter (http://www.thectsc.com/products/mech...p32-42-52.html) and the sealing sleeve that plugs into the mechatronic. If so I would let the mechanic do it for that price.

Its not hard and I got lucky. Of course you have to drain and remove filter first. Disconnect battery/remove connector from the sleeve/unlock and remove sealing sleeve/remove 10 or 13 bolts (they will have bigger heads than the others) holding mechatronic and remove . Its not heavy but don not drop. You will need a inch pound torque wrench for reinstall. T40 torx for screws.

In the "Replacing mechatronics" attachment see page 6. The middle picture shows the sleeve kit and adapter (Circled numbers 1 and 2). Recommend changing all 5 while you have the valve body dropped.

Everything was pretty easy until... the PITA is getting the new sealing sleeve back in once you have reinstalled the mechatronic. Posters have written use Vaseline on the o-rings.

- Maybe when you have the mechatronic out put the sealing sleeve on the mechatronic to check if it will lock.

*** Make sure you remove sealing sleeve before trying to remove mechatronic. Got lucky here and didn't damage anything trying to remove mechatronic before removing sleeve.. ****

To answer your question if your mech is going to do this for 150 and you can afford it I'd let them do it. I would watch them though and make sure they follow the directions attached *TO THE T*.

Oh.. make sure you have 8 liters of ZF fluid for refill.

Have fun

I am still having issues trying to get the sleeve back in. It goes in but the lock does not pop back into position.

There must be a small gap think it's 3mm between the gearbox casing and the sleeve for the locking tab to engage .ie the sleeve must not be pushed uptight against the casing

Bmw tech told me to flush recommended 3 times before you start driving it... Flushing the fluid just once can possibly do more damage. I think my guibo is the problem instead of fluid and such

I'm thinkin if I drop exhaust might as well do an X pipe and delete my mufflers for a dual inlet muffler. Will get rid of my muffler flap sound too.
