How many here have owners manual with contradicitionary information on AT service

Not trying to start a debate but a simple question:

My service booklet says to replace AT fluid at 100K miles, yet the owners manual states it's lifetime. It's kind a funny.

Owners manual is meant to be read by people who lease their cars.

Service manual is written by mechanics. I'd trust the intervals in service manual

I asked the Service Manager at a FL BMW dealer, was told the trans fluid change info was incorrect, and BMW is revising all manuals to state fluid is "lifetime".

Was also told BMW defines "lifetime" as exceeding 100k miles!

FWIW, ZF built the trans and recommends fluid/filter change.

I made up my mind about the change or not, but I'll keep it to myself in the interest of not starting the debate.

If BMW did revise their maintenance schedule to include tranny fluid replacement at 100,000 miles wouldn't that be like the the tobacco people admitting that smoking causes cancer and wouldn't they be held liable?

I agree.

BMW docs should state "lifetime trans fluid" means unit exceeds 100k miles.

Don't hold your breath if you expect to see it in writing.

That's why I discussed the topic with a dealer service manager where I purchased a new BMW.
