Well, the leaking hose was replaced today. Took the mech nearly the quoted 7 hours to complete the job. To the best of my recollection, he had to remove the tranny (the top connection for the hose is above the trans), replace the hose, install the tranny, clean it all up, check for any other leaks, and test for any faults. I took the car out and ran it hard for about 15 minutes, working through the various shift programs and all seems good to go.

I was just told by my mechanics that my car had this problem and the car is out of warranty. I'm hoping that I don't have to replace the whole tranny. If that's the case I might just have to dump it.

If it is only the hoses that are leaking, they are relatively inexpensive to purchase, and not all that difficult to replace for a skilled mechanic.

The entire trans does not have to come out to replace the hoses. It's possible to change them without moving the trans at all (this is how our techs perform the work), but if you want to make the work a bit easier you can loosen the crossmember, put the trans on a screw jack, and lower it slightly to provide more space.

I had this problem last year, twice. First, I put the car into yearly maintenance and they told me the hoses were leaking and they replaced it. And second time, I took it in for a software update and they told me it was leaking again. So they replaced it and they told me if it keeps on leaking that they had to replace the tranny. Because, they figure that it wasn't just the hose it was the screw thread on the tranny its self.
Hope yours get settled soon.

I am bumping this thread because it was useful to me when I was investigating and fixing my DCT's leak. I had transmission oil on the hoses, bottom oil pan and hydraulics side seal. The dealer (Charlie@McKennaBMWService - thanks Charlie!) investigated and found the source of the leaks to be from the side seal and oil pan gasket.

Good to hear that the guys at McKenna got you back on the road!

While I'll defer to the mechs of this forum, I understand that the transmission oil pan gasket is weak and a common leak point. In fact mine was wet when up on a lift last week - not enough to leave oil on the floor, just enough to make the exterior of the gasket and edges of the pan wet.

Anyone have any experience with something similar?

Thanks,

I recently had my car inspected at the dealership, and these line were leaking(the tech let me go in the shop to look under the car with them). I would like to know if I can replace these lines and then make sure the fluid is at the correct level or will I have to have the dealer/mechanic hook the car up to the computer after replacing these lines? I want to try to avoid an $1100 job if the parts are only $260.

Any help would be appreciated.

Unfortunately I don't know the answer to your question. Maybe someone with a bit more direct experience can comment.

Either way, good luck!
