    Hello, I would like to advise someone who is familiar with the topic, or has been in contact with a similar situation.

    Namely, it is an oil (fluid) leak from the automatic transmission.

    One day I went on a 200km route, and that I recently bought a car (BMW, 2.5 gasoline, automat) I decided to go a little faster and so developed the speed of 190 and so I rode the moments. After this crazy ride ( ;) ), I saw that the car stops going and as if the gears start to slip, I tachometer gas goes up and the car does not react. (I would add that it was very cold)

    I managed to get home and in the morning I wanted to see what and how, I started the car I drove 50 meters, until suddenly as if all the oil lost from the automatic transmission and since then zero driving back and forth.

    The car at the local mechanic is, except that I'm not sure if he knows one, the gearbox has been replaced with one from 3.0 engine, the car fired went forward, a reverse error appeared and at the beginning he didn't go back but after some time it was already okay.

    After a day of driving, the car got a gearbox error and stopped driving and as if in emergency mode.

    Then the oil dumped again, my hands dropped at that moment ...

    Does anyone know what it may be, why oil throws away and which way?

    Is the box from 3.0 not suitable?

    Can the sealant at the clutch discard so much oil?

    I am asking for advice and suggestions.

    Best wishes.

    Convector like something: p In addition, you can have the leak in 3 places from what I remember Sealant, crate bowl and mounting on the shaft, not counting the plugs, If you have the opportunity to enter the channel, take a picture of the crate, you can also wash the entire crate, pour oil and fire up and check where it is leaking. Does your inbox have a cooling system? because it is possible that the system can dump you oil and go into emergency mode due to lack of oil. There may also be a problem with the electronics in the box, if you take off the cover bowls, you have the whole driver there, it can also break down. I suggest you find a good foreman from the machine, because in 1 better you won't do it, and it may be that you will be able to charge and load money
