You’ll be good. As explained to my by the indie shop (and online), when you start the drain and fill at a time the fluid is still good (not burnt up), it’s totally safe to drain and fill. For me I was at 81k so I was concerned (car purchased used). They said I’m 100% fine, so I’m at 135k now and even had to have.n output shaft seal replaced and tranny going strong…I too have tge ZF 8 speed in our X5. I do a drain & fill @ 60k, then again at 10-15k. This will refresh your current fluid, to get rid of clutch material particles & replenish due to heat wear on the fluid. If you buy your fluid from FCPEURO, they will honor their lifetime warranty.
