Thanks for your direction. I modified it a little.

DIY: Took about 3 hours as I am amateur. Cost me about $ 200 in parts which included> 3 gallons of Redline D6 auto transmission fluid, 4 quarts of sacrificial Dexron 6 used to assist flushing. New pan gasket, new Trans filter with seal.

A Bmw shop wanted $800 just to drop and clean pan and install new filter and refill. No flush.

All done while car on vehicle lift.

1. Loosen up Trans Fill Plug
2. Remove drain plug and drain Trans-Oil pan
3. Refill transmission pan with 2 quarts of Dex 6 oil
4. Start and run engine for 2 minutes while changing selector from park to Drive.
5. Shut off engine.
6. Drain oil pan
7. Refill transmission pan with 2 quarts of Dex 6 oil
8. Start and run engine for 2 minutes while changing selector from park to Drive.
9. Remove drain plug and drain Trans-Oil pan
10. Remove Oil Pan, clean oil pan magnet and pan.
11. Remove old pan gasket.
12. Remove old filter and filter seal
13 Install new filter and filter seal
14. Install new pan gasket and install oil pan
15. Refill transmission pan with 4 quarts of REDline 6 synthetic trans oil
16. Start engine and run through gears and simultaneously add trans oil until it just started to come out overflow.
17. Run for 3 minutes, stop engine and drain transmission pan again.
18. Inspect transfluid Now it was red enough.
19 Refill transmission pan with 4 quarts of REDline 6 synthetic trans oil
20. Start engine and run through gears and simultaneously add trans oil until it just started to come out overflow.

Seems OK and shifts very smoothly.
