How about a ZF 5HP24 Transmission Fluid Change and Failures Poll?

OOPS My Bad, I lost my head That's what I have 3.0.

Let me say something......I think the majority of you are a little misinformed about transmission fluid changes. The ONLY proper way to change the fluid is to have it power flushed and filled by a shop/dealer with the equipment to do so. I'm all for DIY projects but this is one you should not do in your garage. It is impossible to remove all of the old fluid out of the torque converter even if you drain/refill several times over a short period.

Now this is what I call misinformed.

If you just want to check the temperature for filling, Inpa is easier and faster.
From memory, after selecting the transmission module, there are Analog1 and Analog2 buttons. Under one of those, you will see the temperature of the transmission.

If you prefer to work with GT1/DIS, there are procedures to check the level or fill the transmission.

Here is a 'copy'n paste' of the notes I took while exploring DIS in preparation to my future transmission oil change:
HTH

Oil level adjustement with DIS:
- Main
- Select Diagnostic
- Select E53
- all modules will appear, just click the Right arrow at the bottom right
- Select 'Function Selection' at the bottom
- On next screen, select 'Service Functions', then 'Drive'
- The pop up window will show: 'EGS Transmission control' ; select YES
- Select 'Transmission Control GS1904'; then 'Calibration'; then 'Oil Level'
- Click Right arrow at the bottom right
- on the next screen, select 'Test Plan' at the bottom and answer NO the the question about
the Short Test.
- on next screen, make sure 'Oil-level adjustment is highlighted, then press the Right green arrow
- on next screen, select '1' for 'Oil Level Check' or '2' for 'New filling after removing pan'
- Follow the instructions

That's fine for some changes. When I called my indi mechanic to get a price on the ATF power flush change he asked the mileage and when I told him it had 90+K miles he said he would not do a power flush. He would do the drain and refill 3 times. He said the power flush runs the risk of loosening crude that has built up over a long time and could clog up the works.

Sure you'll leave 10% in the trans over 3 drain and fills. Its a matter of opinion weather this is enough of a change to to be benificial. I say it is. Then change it every 50K to 60K miles, imo.

I don't understand the question and I don't understand the answer. The OP asked for oil temperature and the answer addresses oil level.

Get analog or digital thermometer , they r like $30 bucks on the inter net. Unless you're have a problem it should be between 180F to 210F. Towing a heavy load maybe 215-220F+ or -

Yes, he was asking for a way of checking the oil temperature which is mandatory during filling or checking the level of the transmission fluid.

I pointed him to Inpa that can do it with a direct readout, but since he has GT1, I pointed him to the menu where GT1 deals with 'oil level check'.
GT1 is not just a 'reading' tool, it guides you through a procedure to check something or repair something, and in the procedure to check the oil level for the transmission, the temperature is taken into account.

Interesting. The DYI on this forum just mentions filling until it runs out the hole.

I would assume it's safer to fill it when it's a warmer temp. How much do you think it matters? The pan holds 3.5 qts, in the GM cold. It may expand to 3.7 or 3.8.

here's a discussion on Bob is The Oil Guy about ATF expansion.

Of course this is not BMW related, how sensitive is the X5 tranny to slight overfill from expanding fluid?

I have also seen some DYI that don't take into consideration the transmission fluid temperature, but BMW (ZF?) is strict on this. BMW mentions it in the TIS, and also, there is a label on the transmission pan (on mine at least) that specifies the part # for the fluid and that the level needs to be checked at 30-50 °C.
Knowing how sensitive those trannies are, I wouldn't do it without monitoring the temperature.

I changed mine at 177k miles, and it had never been done. I dropped the pan, changed the filter and topped it off. Be sure the transmission is warm and as level as possible. Today, I'm at 179,030 miles with no issues. whatsoever. I have since drained it and refilled it one time since the initial service, and I've got 10 quarts just waiting to go in. I could not believe how dirty it was, but a drain an refill on removes 45% of the original fluid. So, it's like adding water to mud. The second time I could tell a difference in the color of the fluid, but I suspect it will take at least 2 more times to get the majority of it replaced.

I've been wanting to drain and refill the transfer case as well, but I've read you can damage it if you don't reset the adaptive values. I'm sure the $tealership would be requesting $300 to do the service, so I may just drain and and refill it and take my chances, it can't be worse than leaving 11 year old fluid in it.
