So, habe das gerade gefunden auf roadfly in USA. Damit duerfte das Thema Fuellung auf Lebenszeit zu Ende sein.
Und da das Standardschreiben sich erst auf das 4HP24A eines Audi bezieht (spaeter korrigiert) ist die Frage fuer andere Typen wohl auch geklaert. Also: Lebenszeit heisst 100.000 Meilen. (Empfehlung)

Clarification from ZF Transmissions
Bottom line for those who saw my previous post is this: ZF Transmissions confirms the transmission fluid in the 5HP30 SHOULD BE CHANGED at 100,000 miles.
For those who missed my first post about this, my 2 emails and ZF's 2 responses follow for reference:
******************************
Original inquiry:
Sorry, I don't write German.
I own a 1993 BMW 740iL USA version with 5-speed automatic ZF transmission and 118,000 miles on the odometer. The owner's manual states the transmission has a lifetime fill on the fluid. My question is this: is it still considered best to allow the original fluid to remain in the transmission indefinitely or has further research and experience shown that the fluid should indeed be changed?
******************************
Original response (emphasis added):
Thank you for your interest in ZF Industries, Inc., especially in the spare parts program for 4HP24A 4-speed automatic transmissions for Audi applications.
First, I would like to apologize for the delay, but your email was moved within the ZF organization until it reached me.
In regards to your inquiry about replacing the lubricant in your ZF transmission, ZF does recommend to replace the oil after 100,000 miles. Your vehicle should have a 1055000010 or 1055000029 transmission specification and for that transmission you need a Shell type oil with the ZF part number S671090149 (20 liter canister). Please verify the transmission specification (on the metal type plate on the main housing) before contacting any independent distributor.
ZF Industries, Inc. has a network of independent distributors throughout North America. They offer the wide variety of spare parts for all ZF passenger car transmission applications. For complete factory remanufactured transmissions, please contact your local dealer.
Two types of distributors offer the ZF passenger car transmission product line. Regional distributors and nationwide distributors, such as ATC Distribution Group, Delta Automotive, Inc., and Transtar Industries, Inc., with various locations throughout North America. Both regional and nationwide distributors have access to all the ZF spare parts, kits, lubrications, and literature. In addition, the regional distributors can offer technical assistance or supply complete rebuild transmissions, remanufactured with original spare parts from ZF.
If you are looking for a passenger car transmission distributor, please check our distributor locator on the ZF North America web-page

Clarification request:
Thank you for your response to my inquiry. However, there is still some confusion since somehow you thought my car is an Audi with a 4HP24 transmission, when if fact it is a 1993 BMW 740iL with a 5HP30 (A5S 560Z) transmission.
...
So, once again, should I or should I not change the fluid in my 5HP30 ZF transmission with 120,000 miles on it?
******************************
Clarification esponse from ZF:
I guess that was not my day, since I usually copy an old customer inquiry and change the information for the specific questions. In that email I missed to change the Audi 4HP24A information to BMW 5HP30. However, the content below the first paragraph is related to your transmission.
Sorry for the confusion.
Best regards,
