The 5HP-30 (A5S 560Z) and the 5HP-24 (A5S 440Z) were used in the E38's production run.
The 5HP-30 is used in the 740's until 12/96 and the 750 until the end of the production.
The 5HP-24, which is slightly smaller, is used in the 740's from 1/97 until the end of production.
A little information on 5HP-24 vs. 5HP-30:
http://www.digest.net/bmw/archive/v9/msg05876.html
Your E38 has the green plate. Do NOT use the black plate fluid.

Fill Plugs
The plugs are hex (allen) sockets. For the 5HP30, the fill plug is 17mm and the drain plug is 14mm.
More information can be found in the PDFs at the bottom.
The transmission fluid in these transmissions needs to be Esso LT71141 or an equivalent fluid.

I would add some more specifics on current fluids that meet the LT71141 spec.
Royal Purple Max ATF DOES meet the LT71141 spec so it can be used too.

Liqui Moly Top Tec ATF 1200
http://www.liqui-moly.de/liquimoly/p...oiladb=web.nsf
Kendall VersaTrans ATF is LT 71141 compatible as well.

Link to ZF's Lifeguard5 fluid:
http://www.thectsc.com/index.php?p=p...d=14&parent=57
BG Universal Synthetic ATF
Valvoline MaxLife ATF is approved. PM me for a data sheet.
Mobil 1 doesn't list as LT71141 spec anymore.
**NOTE: Double check the fluid compatibility. Fluids may change.**
It's okay as long as it meets the LT71141 spec
It's recommended that you use the ZF Lifeguard5 fluid as it was made for these transmissions.
If you drain the fluid, about 6L will come out. It's always good to buy extra just in case. You can flush the transmission using the transmission oil cooler located on the driver side by the radiator (left hand drive vehicles). Due to the length of this thread, I'll provide a link to a thread that discusses this.In modern transmissions, the oil is a "component" that needs to match the different transmission functions and materials as perfectly as possible. ZF transmission oils are developed especially for the individual transmissions and adapted to their specific requirements. Off-the-shelf products usually have to meet the specifications for different units and therefore have to make compromises, preventing your ZF transmission from reaching its full potential.

Here's an excellent DIY thread on the flush.
http://forums.bimmerforums.com/forum....php?t=1945093
It's fine if you don't flush it. Here's a another video by Edwin at a ZF shop in Germany getting his transmission serviced.
The filter should only be from either Filtran or ZF.
It can be purchased from the dealer.

Information on disassembly, diagrams, how-to's (including how to refill/top off), etc., can be found on the PDFs attached. I would like to thank fellow member Mike in CT for the last three.
As for the shifters and the TCM
The step-tronic shifter does not allow accidental downshifts and upshifts to prevent over-revving and low rpm possibly stalling the car.
The ADAPTIVE programming (ATC) has it's own "winter" program that will automatically be selected when wheel slip is detected. *Winter mode is one of the NINE adaptive tranny programs that occur automatically based on driver or environmental inputs:
- extreme economy
- economy
- sport (adaptive)
- winter
- stop-n-go
- up-hill
- down-hill
- curve program
- cruise control program
When in "M" mode...the transmission starts & stays in the gear you have selected (which is only 2,3, or 4)...it does not jump to a gear that is not indicated (no 1st gear as you had supposed). *When in "D"...the tranny starts & stays in 4th gear
When in "S" mode (S2, S3, S4) the transmission will START in 1st gear and shift up to and down from which ever gear you have selected on the gear shift.
(Last six pictures courtesy of Qsilver7)
For US spec models, the step-tronic shifter is only available for the 1999+ 740i w/ the sport package, and 750iL. The 740i without sport package and the 740iL did not get it. Some Canadian spec non sports got the step-tronic shifter. Euro models had the step-tronic shifter from at least the 1996 model year.

I would add some more specifics on current fluids that meet the LT71141 spec.
Fluids that I know of (approximately in order of cost):
Castrol Import Multi-Vehicle ATF
Mobil 1 Synthetic ATF
Amsoil ATF
Pentosin ATF1 - often listed as a direct substitute for LT71141
ZF LifeguardFluid5 - Official ZF fluid
Valvoline MaxLife removed the LT71141 spec from their label and datasheet, so I am leery of using it.
Thanks Added it.

Any links on how to drain, re-fill and / top up transmissions.
PDFs attached on re-fill and level check procedure. Fluid recommendation is dated. Esso fluid no longer exists.
Link to current ZF recommended fluids is in the link below under "Fluids & Lubricants" downloads, "List of Lubricants" document.

I believe you could fix fluids, as long as they're within the lt71141 spec for the certain application for your transmission.. I have no clue what was put in my transmission from the shop i took it to, so now i have to do a test on it and check and see, but most likely just going to throw in valvoline maxlife atf, which should also be added to the list, which is a completely compatible fluid
Treasure your 5HP30s, that's such a nice solid unit compared to the 24.
2000 BMW 740iL | 225,XXX miles | VW MAF | Bavarian Auto Coils | Timing Chain and Guides DIY Complete | M60 Manifold | BDC Polished Throttle Body| Custom Tuned | Performance Gearing 3.46 LSD| Magnaflow mufflers |
|1997 ///M3/2/5 | 104,XXX miles | Boston Green Metallic|2006 X3 3.0 SAV|121,XXX miles| Silver|
For 5hp30 and 5hp24 replace the tranmission pan torx screw with stainless steel Hex head Metric size M6 X 1.0 X 25 with washers for easier access for future service and don't forget to put anti seize.
For the 5hp30 only. Transmission valve body must be rebuild if performing its first oil change, There's a defect with the transmission check balls shrinking due to material problems, failure to perform VBK update before changing fluid may cause clutch and hardware failure, also vBK update also changes some of the valves (don't know the right terminology) and shifter plunger. So it's very important to perform this update.

No mention in the listed specsifications of "Mobile LT-71141". Just a personal preference to go with a product that the transmission manufacturer has recommended for use. Don't even believe that Bav Auto sells the Mobil product anymore, they sell the ZF Lifeguard Fluid 5.
Is this the best dipstick mod around?

Ive called valvoline myself many many times, reguarding which fluid is a compatible fluid for the ZF5HP24 And ive been repeatedly told Valvoline Maxlife DEX/MERC ATF. Also been to several auto stores, and still show the bmw lt71141 spec accordingly. I am not sure why it is removed from their product data sheets, But I can say this again, It is compatible
5hp30 valve body removal rebuild and reinstall
http://www.darkstarmediallc.com/bmw/...dy_rebuild.pdf
I highly recommend it because there is a chance that your old check ball has the degenerative material defect, id play it safe and rebuild the VB, The VBK ts also replace some O rings for the oil pick up risers, the electrical plug to TCM, solenoid o rings prevent leaks, while the VB is dismantled you can Clean up any caked up materials that is stuck on the VB, update the valves for better shifting and the get the updated gear selector plunger. Its a very straight forward easy job a lift would make it easier and it would take a weekend to do it.
So the 5hp24 doesent ever need a VB rebuild? score!
