Delayed Shifting Transmisson - 325i 2006

Driving 2006 325i. Automatic. Purchased as CPO. 135K miles. Well maintained per BMW schedule through CPO at dealer. At local bimmer shop since.

I've always struggled with the non-serviceable transmission guidance issued by BMW having always at least done fluid refresh every 40-50k miles in my other vehicles. Despite reservations I stuck to the guidelines and have not serviced the BMW. Now wondering how much I've screwed myself having read this forum.

Shifting has begun to drag a bit into higher RPMs before the shift is actually made. Shifting is smooth, but just happening at a different place than it usually does.

Praying this is not the beginning of the end of my tranny. I was told that at 135K, it might actually do more to expedite the transmissions death to flush and change the fluid, etc. at this late point. Does that make sense to anyone? Any other thoughts about the delayed shifting?

Appreciate any advice. MD

First, what is the opinion of your independent Bimmer shop? BMW automatic transmissions without fluid & filter changes are a known fail item.

If, indeed, your transmission is emitting death rattles then a fluid flush and filter change may postpone the inevitable for a few more mile or it may speed the final destruction. It's your money and your choice. The BMW automatic was dubbed "Factory Fill" then BMW walked that back and said "Meh, change the fluid/filter at 100,000" but no promises!!

My 2006 325xi has 115,000 with fluid/filter change at 110,000. A fluid analysis shows the fluid we replaced was "Factory Fill", contained various amounts of metal contaminants but the lab states the contaminant material totals weren't so large as to indicate eminent failure. I'll do a filter/fluid change at 130,000 miles along with a lab analysis and see what transpires.

My humble suggestion? If you love the car then change the fluid/filter, cross your fingers and start looking for a rebuilt transmission (check the advertisers in Roundel or Bimmer). If not, it trade-in time.

Wish I had more complete advice and a better answer.
