Topic is copied and pasted from a private seller of a 03 4.6is X5. I've had the same issue since earlier this year.

If I leave it in sports mode, the shift would be normal.

The harsh downshift is happening less now, but not because of anything I've done mechanically.

Typically when i'm slowing down nearing an intersection, towards the last 2 car lengths as the speed nears 0, the sudden jerk into first gear would happen.

It's not very harsh yet, just a sudden jerk from 2nd to 1st. I can minimize it if I brake early and let the car coast to a longer and slower stop.

I bought my 4.6is last march with 95,000 miles. The first thing I did was replace the transmission oil, filter, and the sump cover.

Does anyone know if this is a prelude to something worse to come for the transmission?
