    It would help to know exactly what vehicle > > >

    you are talking about. BMW has used automatic transmissions from both GM and ZF which have different ATF requirements. The ZF transmissions come filled with a "Lifetime" ATF available as Esso LT71141. For years there was no "compatible" fluid for LT71141 but now there are several on the market from Valvoline, Castrol and others. The LT71171 is available from different sources at a cost of $20+ per liter. I just moved from LT71141 to Valvoline MaxLife which cost about $5 per quart. Others have made the move long before me. The GM transmissions use a standard Dexron fluid. Tell us which BMW you have along with the build date and someone can tell you both which transmission you have along with which ATF you can use.

    Alternatively, there is a sticker on the bottom of the transmission pan which lists the ATF requirements.

    In that case, any Dexron III ATF will do nicely. >

    What a lot of us have done as a matter of routine maintenance is to use a turkey baster or similar device to suck out as much fluid as possible from the Power Steering reservoir and replace it with a good synthetic Dexron ATF such as Mobil 1. Repeat this 4-5 times over a week or so of driving and you will have replaced most of the old fluid without having to make a real mess by draining a system which isn't designed to be drained - i.e. with a central drain point.

    In future posts, if you can provide a bit more specific information up front, it makes it a lot easier for members on the E39 board to offer assistance.

    Also, if you have a low fluid level in the Power Steering reservoir, you must have a leak. Look at the hoses coming off the bottom of the reservoir. If they are wet and oily, those hose clamps need to be replaced. It's a common problem and your car is right at the age where this little bit of maintenance needs to be performed.

    The only leak that I see is around the cap. I asked the BMW tech @ the dealer one time and they say its normal to have a leak at the cap of the reservoir. Almost 10yrs w/ the car, I never top the reservoir, but I always have to clean around the reservoir. Do you think I have a bad cap or it is normal?

    If it leaks where cap meets the reservoir, replace

    the o ring. It's hard to see it and it's probably hardened by heat and age. Also, the cap has a vent on top that will leak the fluid if you keep it topped off to high. You can also stick cotton of the q tip in the vent. It'll keep venting and still absorb any extra fluid.

    That BMW tech should work at a Dodge dealer > >

    It is not NORMAL for there to be ANY leaks on a BMW. The O-ring you need is Part # 3 on the Real OEM diagram. Should be about $2 at your dealer and it's a LOT smaller than depicted on the exploded diagram.
