leaking transmission fluid
#1
Hey guys. My 2004 530i with 70,000 mls has a transmission fluid leak.I looked under the car today and the cover underneath the car was wet with fluid, so I dropped the cover and noticed transmission fluid all over the bottom of the transmission pan. I want to check the torque on the pan screws and just service the transmission to full. Can someone please tell me the torque valve for the transmission pan screws.I serched and could not find the correct valve. It is an automatic transmission. Thanks

Are you sure that it was leaking from the pan not other area of the tranny ?

I have the same problem a few months back I noticed a leak, thought it was some residue of an old oil change, got it cleaned and now I have noticed the same problem. In my old 1999 E39 when I had changed the tranny oil the pan was made of metal now in the 2004 E60 I noticed it is made of plastic and the since there is cover under the car which covers the engine and tranny they decided to put a plactic oil pan ( to also reduce overall weight of the car)which gets warped after sometime due to heat. The cost for the pan with built in filter is 260 + tax from BMW dealer. Oil will need to be changed too the cost would be around 800 $ if one does it through an indy shop. Just an FYI www.germanautoparts.com has the part for 156 $ plus tax/shipping, hope this helps

+1 I too just had the tranny oil pan and seals warranted on my 06 550 due to leaking. The tranny pan had warped and the seal needed to be replaced as well.

It was the pan leaking,even though the screws were all torque correctly. I changed the pan and reserviced the fluid and that fixed the leak. Car drives much better now, no leaks. I bought the pan an fluid from rmeuropean. I reused the screws, although I wished I should have changed them all. Some were a pain to get off ( i had to use valve grinding compound on the torx tip to get some off). If anyone is going to do this job, get new screws. Auto zone sells a hand pump for less than $5.00 that works great. I used an extra piece of hose to fit into the end of the pump hose, so that I can pump fluid sitting at the side of the car instead of being underneath the car pumping the fluid. I used a 10 mm deep 3/8 drive socket with a 12 inch 3/8 extension and an 8 mm "L" shaped allen (hex) wrench to remove the fill plug. Piece a cake to remove, worked great.

How much did it cost you to do everything?
