Thank you LEZ,
You clear up a lot in my mind. I went to the dealer yesterday, and asked them the same question. All they said is that it is not required to do any service on the tranny. All I want is a clear answer. And you gave it to me. Thank you !!!. Anyway, this bring me to another worry. The reason is I have a friend who has a transmission rebuild shop. He said that the BMW 5 speed automatic transmission, a non technical car owner cannot fill the fluid. Which is true for my case. He also said that the transmission cost is about $6000.00 to replace not including labor. And it is likely to break down at around 130,000 miles. I don't know about everyone else and you, but it is very scary for me !!!. Like I said, I am not technical. But I also an ME and believe me anything mecahnical will wear out. I am going to have it service, soon.
No, I live in Southern Cal. and I bought my 95 840Ci from a private owner and it is black. So I'm sure it is not your car that I bought.
By the way, I went to the dealer and saw a real 850CSi. It is fantastic !!!. But guest what ? He is going to have to replace his headlight very soon. I guest we are all in the same boat. You are right, 17" wheels is a little bit small. I think 18" wheel is perfect. Lez, where did you buy your H&R, Bilstein shock ? Any good place on price ?
Did you get your M Mirrors done, yet? You should... It looks fantastic !!!. And then when you done, can you send me the pics and the part number. Thank you.

: : Oke here is a fact :
: You don't have to to replace the transmission fluid in your x40i BMW since 1995 ever - period. That means 540, 740, 840.
: Personly I don't trust this completely becuse the transmission has a conventional filter inside, that means it is replaceable. So I wanted to replace mine after 100k miles and yes you can. You have to use a special synthetic oil (from BMW 1 gallon approx 120USD) and a new filter kit (approx 50USD from BMW). On the side of the transmission there is a drain plug (i belive on the driver side) so you can drain what's in. Drain it to a clean pan becuse you might reuse all or most of it. Take the pan off (but be very careful becuse made out of aluminum) and pull the filter (I think there is one or 2 screw involved) install the new filter, oil pan gasket and put a pan back slowly. Follow the "center to the side" method when tightening the screws. Do not overtighten them becuse as I said aluminum so it can break easily. If everything has done you reached the hardest point refill a tranny. On the middle of the pan there is a deep hole and a screw inside. That is your refill hole. The oil you have just drained most likely to be reusable except if you see small particles, dirt in it, clean it with a good filter use a magnet to clean the metal powder and start refill. As I said you could buy a new oil 1gallon about 120USD, but it might worth it. You are going to need some of the drained oil anyway becuse the refill is about 6 quart and you can only buy per gallon. I don't think anybody wants to spend an another 120 on 2 quart. So refilling you probably need a fluid transfer pump and a long hose to refill and the correct oil level is basicly just below the hole. If you overfill the oil will come out of the hole. Pain in the a.. procedure but can be done and yes kind of an expensive, compare to regular transmission.
: A few people told me I could have used a Mobil1 syntetic trans. oil from Autozone (about 6-7USD/quart) or any kinf of synth. trans. oil. I tried to call several places for the recommended (by owner manual) Shell oil, even Shell-USA but they didn't have anything. Later I found out AutoZone selling Mobil1 synth. but was to late.
: So you might want to ask your stealer to do this becuse it is a lot of work under the car and in the middle which makes everything a bit harder.
: They probably ask for 2-3 hours of labor but the parts are going to be about the same. 120 for oil, and cca. 50USD for the new filter/gasket.
: note: I have a can of oil (1gallon) and complete gasket/filter set for sale but only if you are close to Florida. (the oil is really heavy so might not worth to ship) I bougth this kit for my 2nd 840 but then it turned out i have full warranty on the car so the delare would do this for me for free. (I paid wholesale prices for everything, as I always do)
: Good luck !
: BTW : Where are you ? You started posting questions right after I sold my '95 840Ci Silver baby in Florida to a delaer. Maybe you are the one who bought it from a dealer !?
