transmission fluid flush question

[DanX5d]

OK, at the risk of upsetting Dick Thrust and any other extremely well read forum gurus.....


As the owner of a late 2004 X5D that I purchased with 185K on the clock, the transmission when hot lurched quite badly into 1st when pulling up in Drive N mode. So I got the guys at Autologic to drop all the fluids , flush the transmission which can be done with time, and the first thing I noticed is that the lurch was reduced about 50% when hot. That said it has covered another 10K and the lurch is starting to come back and I am getting fed up with shifting into S mode when slowing to a halt (Changes the shift pattern and selects 1st while still rolling up to a halt.) Another fluid change is my next option or some work on the transmission to adjust the 2nd gear band or solenoid operation if possible.

If your transmission is not behaving badly, maybe an oil sample analysis could be performed to see what else is in the oil. Changing the fluid to fresh correct specific synthetic transmission oil would seem like a good idea to me.

Cheers, Dan.
