There are a several pictures how I did it without a mess.
As far as the tools, I used an infrared thermometer ($25-$40) and read from the cooling lines not the pan.
Oil pan should be open only at 50 C degrees ! It is stated on the pan.
When you reach like 60 C degrees and you are still filling, you need to stop. Then is the time when it will overflow regarding the fluid level in it. Let it cool and start again. Even after you get the right level at 50 C degrees , drive the car several miles and recheck again. You will need to add again if you check the level at 50 C degrees.
Sorry but this is wrong. If you reached a temp of 60, it would be overflowing anyway, there would be no question of getting any more in.

If the temp reaches 50 you have to stop and let the box cool down, which takes a long time. The point here is that if the fluid has been topped off at 50C, then it will reduce in volume as it cools, such that at start up in low temps there will be insufficent fluid, hence the whirring that is reported.

The correct way is to start from cold, and fill box until it overflows, then start the engine and quickly resume filling, until it is just overflowing again, and keep this process going until the temp reaches 30C. Then replace the drain plug. This way there will always be sufficient fluid. During the fill process, the gear lever should be in manual and moved through the gears, pausing a few seconds in each, to purge any air.

Its no good checking the level when the box is cold either, as oil should most certainly run out. Instead it should be run up to 30C, then checked with the engine running, when it should be just trickling out as above.

Whirring has also been found to be caused by some non OEM filters which lack some internal bracing allowing collapse and consequent noise.

@ na2998. What you are saying is not entirely true. The "shudder" he is experiencing could be caused by his torque converter failing to lock up and the tranny shifting between gears. Here's the test. When your tranny starts shuddering, move the transmission mode selector from D to 4 or move the mode switch from A to M. This puts the tranny in manual or sport mode. The transmission should not shudder cause it now has different shift points in Sport mode and no shift points in Manual mode. Anyway, the TCC relies on signals from the module. The modules sensors work off of fluid pressure, so, cloggs and thick/hunt fluid can jack the shifting quality. I say change the fluid. Do a simple drain, filter fluid change. Should be about 4 qts. Runs tranny, shift through gears and top off fluid until it over flows. You have to work quick as the tranny must be kept within 30-50 degrees celcius. - Big Biz IL.

The official filling procedure is located on page 4 of the following diagram:
http://akpp-city.ru/pdf/5HP24.pdf

If you have INPA on a laptop with the appropriate cable, you can read the temperature of the tranny.

If not, you can read it with a multimeter that has a temperature function.

I have done mine at 60 k and recently at 80k miles in my garage. Filter and gaskets were changed both times. It gives me peace of mind.
All e38 should have had this done by now even tough the factory calls for life-time oil. life-time oil is not a lifetime oil. ZF says the fluid should be replaced at 10 years if the fluid is in use.

A fellow e38 owner went to ZF germany and had his transmission serviced there. He was told to change the oil every 50k miles and fluid + filter each 100k.
His post can be seen at http://forums.bimmerforums.com/forum....php?t=1163744
Personally, I will do my best to keep the transmission in good shape especially since I am always driving in sport/manual mode. I never drive it automatic.

Hope it helps.

I've replaced 2 or 3 times trans fluid -admittedly not on 7 series. Each time tranny quit short time after. If it says "lifetime" -trust it is
Seals in the original tranny become quite acidic due to fluid wear. By putting low ph (new) fluid into tranny, we cause more trouble by allowing those old seals to suddenly get exposed to new fluid with radically opposite ph factor. This is what screw them seals up. If I had to change I'd change half fluid only, so that chock of new fluid wouldn't ruin the tranny too soon

Depends what you meant by 'replaced 2 or 3 times trans fluid'. If this was done by draining the fluid via the gearbox drain plug only, then you certainly didn't change even half the fluid, since this action doesn't drain the torque converter. For example a 5HP30 box fills from dry with about 13 litres, yet only some 5.5 litres can be drained as above..

Smile ESSO vs. Valvoline vs. Mobil One tranny fluids

BMW2QNJ2LE - 1) I am new. My bimmer is 2001 740i with 93000 mi. The manual indicates that the tranny fluid is life time. What is the definition of lifetime? 80K, 150K or 200K or 300K. Nothing is forever. Mine is a nice 2nd owner car. I thought of changing the tranny fluid for long lasting transmission. (on the side note: My 2000 Camry lasts 250K without tranny problem with fluid change every 50k mi. I recently change the oil & tranny seals).
2) First reverse in the morning, my Bimmer jerks noticeably. Forward shifts are smooth. Reverse when hot does not jerk. Is there anything that needs to do to fix this jerking? Low tranny fluid? or something else. Few days ago, in the morning, my bimmer displays "TRANS. FAILSAVE PROG." on the display cluster. It lost acceleration in the ist gear. in the afternoon, it is back to normal. Any concerns at this point?
3) For history records, I would like to ask M. Wong (change @ 75K and ...), h711k (change @ 128K ...), balance (@140K...), xxbimmerboyxx and others: since your postings were dated back in 2008/2009 time and today is Dec 2012. You all must at least put 30,000 to 80,000 mi on your transmission fluid. If you would like to share your real life experiences that would help me and other bimmer lovers out there to understand more the pros and cons of changing our bimmer tranny fluid! ESSO vs. Valvoline vs. Mobil One tranny fluids. Your experience sharing is greatly appreciated and it will be a document for future reference in the Bimmerfest. Thanks. BMW2QNJ2LE.

I changed mine @ 150K. It was the original fluid & filter. Tips: http://www.bimmerfest.com/forums/sho...818&highlight=
Almost 19 months, 15K miles later, still runs good. In the mean time I had to refill a little bit since I have a tiny leak at the oil pump seal.

1) Consenus of opinion is to change the fluid after 60k miles. It is essential to understand the fill process, and to change the filter with an OEM one. It is not a simple drain and refill. The original spec Esso fluid is still available, now branded as Mobil.
2) Your battery is probably failing-this message is typical of low voltage. The top of the battery post should should be date stamped with the week and year of manufacture eg 51/01. 5 years old is about this limit for these cars.
3) http://www.kneb.net/bmw/E46/Auto%20t...id%20chart.pdf.
Measure the drained oil and compare with the value in 'Without torque converter' column. Then you'll know if the box was short of oil.

1. Hi abry42000, Below is FYI (See link: http://www.kneb.net/bmw/E46/Auto%20t...id%20chart.pdf. to confirm the data) :

FILL CAPACITY:
TRANSMISSION MODEL 50HP30 (A5S 560Z)
WITH TORQUE CONVERTER 13.1 LITERS
WITHOUT TORQUE CONVERTER 5.5 LITERS

2. I thank Chrisn7 for your advice and info & links.
3. 2001 BMW 740i - At 95,000 mi, I just changed my tranny fluid using Mobil One transmission fluid and Febi filter. The old fluid was greyish-black with sluggish paste of metal? particles. It took more than 2.5 hrs for the job.
I researched and found that the technical specs of viscosity @ 40 degree C and @ 100 degree C between Mobil 1 and BMW ZF LT fluids were within the testing errors. They are every close with each other.
It has been ~1,000 mi with the new Mobil 1 transmission fluid. The jerking on reverse is gone. Transmission performs smooth as before.
4. My 2000 BMW 740i sometimes does not shift into 3rd/4th/5th gear when it gets hot. It speeds up at 40-60 MPH @ 4000+ RPM and does not shift into lower gears. It only does that when the transmission is hot (~ above 210 degree F which is measured/monitored with a digital thermometer) I changed the transmission fluid with Mobil One as did I on my 2001 740i and it does not help. This car is approx. 140,000 mi. I am thinking about installing an extra transmission cooler for this car to extend the life of the transmission b/c I live in Houston, TX. It will be hot and I need the A/C @ full time. Any advice or help is greatly appreciated. Many thanks in advance.

Changed the fluid and filter on my 1995 740i at 112K when I got it. Used Redline D4ATF
and got the filter and gaskets from autohausaz.com. Fluid does not last forever. BMW knows most Original owners will trade the vehicle before any heartache soooo...!
When I first got it, the tranny was a little slow and could feel it. Very quickly after the change it reall smoothed out and "I swear" improved gas mileage by about 1.5 mpg.
I now have 131K on it and have had NO problems or regrets. The change is a fairly simple straight forward process. Do not buy into "lifetime fluids"...ask the manufacturers, or a chemical engineer.

I have 117K I changed it the first time at 60K then again at 80K and I just changed it again, the Lifetime trans fluid from what I have read is just a scam to get out of warranty work by BMW, I believe it because fluids in general just do not last forever ( I think about 30K would be more of a reality ). When I changed mine I went went to a tranny shop and changed the whole 11 ( approx ) liters with the a complete flush. I purchased ZF on Ebay for $220.00 bought the filter Kit from OEMBimmer parts for like $65.00 then paid the guy $100.00 to flush it out we also cleaned the valve body at the same time.

Insanity. The particles will block filter, reduce flow, increase heat and potential to fail. If there are in fact that much particulate, you would definitely want to change. Think if someone told you don't change your engine oil, because the particulates in it are good for you engine????

98 e38 tranny fluid and filter change

Changed my fluid and filter at 105k - it's well documented on several websites and was pretty easy. Ordered filter kit from Bavarian Auto - came with everything needed including gaskets, new plug, and correct amount of recommended fluid. Recommend the BAVauto blog with Otto for instructions and tips. Transmission shifts well. This is routine maintenance! Not sure how anyone could be convinced that particulates "help" performance - the magnets and filters are there for a reason!

One trick I'd offer; a 1 gal fluid pump would work so much better than using the transfer pumps (pint-at-time siphon pump) that are messy, too time consuming, and cause you to probably burn your hand at least once on the exhaust if you're filling with the car up at correct temp.

TRANS FLUID CHANGE 1998 E38 740 iL

I own a 1998 740 iL E38 BMW with 175,000 miles. It shifts smooth and quiet. There are no leaks and under carriage is dry. I do not believe it has ever been changed, I have put 20,000 on this car and still is same, did tune-up, all filters NGK Spark Plugs, cleaned MAF and now getting a great MPG. In this dilemma what to do I asked a German Master Mechanic in my area, He only works on BMW's I described my car (Model, Milage) and he told me if the car shifts properly and smooth, no leaks and no whining noises, DO NOT TOUCH it. He advised me if there is any strange shifting patterns or noises, then at this point it needs to be checked. He also quoted me that to properly do this with the OEM (Only Fluid recommended) it would cost $800 plus filter....

Going to listen to the German BMW Mechanic at this time and I am NOT CHANGING THE TRANS FLUID.

At $800 I will fly to where you are at and change the fluid for you. You are talking about $50 in parts and max $120 fluid all OEM spec's, and about 1-1/2 hour labor.

Trans fluid

Yes, I am in California, it is expensive here, I would not pay the $$$ I will shop around, however I want this done PERFECT, I am keeping this car as long as possible, so I have been reading about this a lot, the Fluid that is recommended by BMW is not cheap, and I will only put the BEST in this car.

So should I change it at this time, even though the TRANSMISSION is shifting perfect?

Thank You for the advice

If the tranny is fine then now is the time.

If you wait until a problem occurs then what happens is that the fresh detergent in the tranny fluid cleans away the fibrous gunk and fluid pressure decreases. It's this gunk that is making the tranny shift right in a worn tranny.

By the time you wait for a problem it's too late.
