Transmission Flush - Do or DON'T??

Also, I posted above a few links to some amazon kits for the service. Do those look correct for an 08 X5 E70 3.0si with the ga6hp19z transmission?

Thanks!

That's the same ATF I used. I have an E53 4.4i, N62.

The kit looks like it has what you need, but I'm not an expert. EDIT: It doesn't list E70, but does say X5's in that model's range. It will depend on your transmission. I like to use FCP Euro or ECS Tuning because you can search by exact year and model more easily. Is this the right one for your engine?

I bought a kit from ECS Tuning because I wanted quality parts. It doesn't have as many parts. We reused the bolts for the pan. They were fine. No leaks. On mine, it's aluminum and it didn't need to be replaced either.

For E53:

Edit: You don't change the pan twice, you use the drain hole to drain it the second (and, possibly third) time. I did it three times to get more MaxLife to original fluid ratio.
