2007 525i automatic transmission leaking
The transmission sealing sleeve is leaking at less than 45,000 miles on the car. Apparently this is a common problem according to two different shops that I went to. Has anyone else had this problem? It seems like a manufacturing defect for a transmission with lifetime fluid to leak so soon.

Any information would be appreciated .

Thanks, Tom

What part are you referring to exactly?

It is a transmission sealing sleeve. A $400 fix.

DEATH2000 07-21-2012 11:06 AM

Do you know the part number or have a part diagram?

No, I do not have the part number for the 2007 525i automatic transmission leaking seal.

I am just surprised that no one in United Bimmer has not had this problem. Both BMW shops that I went to said that this is a common problem. I thionk that BMW should replace the seal since the car had less than 45,000 miles and it seams tobe a common failure.

I have a 525i 2007

The dealership:

"There are 2 oil leaks, one at the oil filter housing on the left side of the engine block & one at the transmission mechatronics sealing sleeve. The oil filter housing requires replacement of the seals & the transmission leak replacement of the mechatronics sleeve & pan. I don't recommend either repair be performed without a lift. The mechatronics sleeve a very specific repair measurement. If not placed correctly your car will not start. Of the 2 leaks your transmission leak should be repaired first."

Found an indi Certified BMW mechanic that is hooking up all this and then some for only $450. I already paid for all the parts down below. Repairs should be started this weekend or next weekend depending when all the stuff come in. I'm not paying $2300 to do all that stuff at a stealers + what it cost to do everything else. All parts are OEM. ZF and INA are original parts on the BMW

Using forums, you never know who might be using it. I am glad he was a BMW certified mechanic that works for a BMW stealership to do the work for me on the side.
