Transmission Service?

I recently had my car serviced at the dealership and they noticed that my transmission sleeve was showing signs of wear. Note, this is not the transmission itself. Anyhow, I took it to a BMW specialist to get a second opinion and they agreed that the sleeve needed to be replaced. While at the specialist, they suggested that I should have them perform a transmission service (I'm assuming flushing the fluid and replacing the filter) while they were replacing the sleeve to save some money on labor costs. I'm currently sitting at 46K miles and they suggested the transmission service should be performed around 60K miles. Yes, it would be nice to save some money on labor since they could perform the service while replacing the transmission sleeve, however my question is whether or not you think this is necessary. I know that BMW's have "Lifetime" transmission fluid, so I'm skeptical as to whether this is needed or just recommended. Thoughts?

No such thing as "life time" fluid. Fluid will break down over time and usage so personally I would dump the old and put in the new since they are already servicing it anyway. Won't hurt unless it's a big difference in cost for the new fluid, then you have to ask yourself if it's necessary. At 46k, I would say not necessary but if the cost to do it is small, then I would recommend doing it.

I hate that term "lifetime" as well, as Pablo mentioned above ALL fluids break down. If they are already going to be in the area have them swap the fluid, since they are already in the area, it should be a very minimal charge($20-50 for fluid/labor). I recommend swapping tranny fluid about every 75k-100k miles. Just my 2 cents

Just so you know, the filter is built into the tranny oil pan on the ZF HP26 transmission;, so it would just be a fluid change.

Dealership will probably charge an hour of labor and an arm and a leg for fluid; so about $150-250 or $80-120 and 2 limbs

Although, a dealership will say it is difficult and they need to hook it up to some machine and keep the car between certain temps. In all seriousness, it's not rocket science; I say take it to a trusted tranny shop it's not rocket science to change the tranny fluid.

If there doing work on the trans,they will have to replace it with new trans oil because the old oil would be drained out. I had my trans fluid change in my S550 @ 40k miles for free because the dealer had to fix something in my trans. The cost would have been $600.00 for the trans change/flushed if they didn't have to fix something in my trans.hope that help

In order to get to the harness sleeve, you need to drain the fluid and remove the pan. The filter is built into the pan and is only $125-$150, so I would definitely have that changed out. Regarding the fluid, I would not reuse the fluid. Spend the extra $80-$100. I had a leaky sleeve and dealerships and independent shops wanted anywhere from $800-$1,300. I bought the parts myself and did the labor in a few hours. It was a pain since I didn't have a lift, but it only cost me a little over $300 for a new sleeve, new pan, and new fluid. I followed the service bulletin procedure on the torque sequence and fluid fill process.

Doesn't the bulletin require you to hook the car up to the computer once you've finished filling the new fluid? I read the fluid change procedure and most of it seemed straight forward. The only thing that discouraged me was the last step... Which was the computer hookup.

I didn't do any kind of 'computer hook-up'. The fluid fill procedure required turning the vehicle on, running through the gears, waiting for the fluid temp. to reach a certain degree, and then top off. I believe programming is only needed when you are doing a mechatronics replacement.

Mein Auto: 2004 645 Ci Convertible
Hello, I purchased a 2004 645 Ci Convertible last Aug, and I love driving this car, escpecially thru the turns.
I have approx 45K miles on the car, and I have noticed that the trans pan is leaking, possibly cracked. I like to do all of my own work and I need to know where to get the service bulletin procedure for the transmission pan/filter assembly and the installation of the new trans fluid. I did not even see a trans fluid check or fill tube?

Also, does anyone know where I can buy a service manual, or a CD of the service manual.

Thanks in advance. Louis

Transmission oil

I went to my local BMW dealer and asked for the cost of replacing the transmission oil, could not believe the price 400 + or $600. There is 9.5 litres in the transmission, two bolts to undo and re-tighten. They are basically charging 40 per litre which is crazy. You cannot buy it separately as it only comes in the big barrels. They told me they keep 1 litre bottles so they can do top-ups or sell to the independents.
I could understand 20 per litre but not this. However the M series 3-5-6 all have the fluid changed as part of a major service as standard at a pre determined mileage.

This might be a dumb question, so sorry in advance, but how does one refill the transmission when there is nowhere to fill it at?

I got my transmission fluid replaced jus a month ago, and the whole transmission got mess up, and I need to replace the whole transmission, and cost me $5200.00.
You will be risk yourself if you exchange the transmission fluid, I heard it is 20% of failure rate which did happen to me.
Some internet information suggests that if you never replace the transmission fluid every 30000 miles~50000 miles, then you better leave as it is?
My be you can find more valuable information?

You can purchase a manual on ebay for $10-20 bucks.

My Transmission fluid has been flushed by BMW twice 35K miles and 75K miles. When I brought it in for the brakes to be replaced, the service writer said it needed to be changed also after he read my key. The second service was covered under BMW extended maint program that I paid for. Hope this helps!!

Unlike engine oil, BMW does not have a recommended trans fluid changing interval but I got mine changed at 56,000km (35k miles). Cost me about $600 but what a difference it made. Car drives so much smoooother. Def recommended.

A pal's 645 developed a trans fault at 75k miles. It will cost about $9000 to replace. You can work out the math...

Oh, Happy New Year to All.
