It shifted fine before the oil change. It must be electronic of the fluid is thinner than the old black much. Again I used all OEM stuff off the tag off the trans.

Is that all you did from the original post? Pan/filter/fluid change? I'm not sure which tranny is in the 2002 4.4i. 5hp24 I think? If all that was done was the above, you are probably having pressure issues. As you said the fluid is thin, the ZF stuff is very thin. If you did not replace the valve body seals at the minimum, it's probably not holding pressure.
Now, what you can try... and I have not done this personally, so I am just passing on info. Try using the Valvoline multi vehicle ATF. It is thicker and I know of a YouTuber (I know, I know) who only recommends that if just doing a pan and fluid change. It is thicker and will help with the old seals. I was going to use this, but the trans service kit I got came with Liqui Moly so I'll be using that instead. The YouTuber in question (Nathan's BMW Workshop) seems very knowledgeable, but it is just that, advice. He said it's brought back almost every trans he's put it in from rough shifts and other behavior. It's a cheap thing to try at any rate...
This is the stuff:

Thanks, I'm hoping so. As is typical with this vehicle, once I got down there I found it needed a whole host of other things. I rescued it before it got to the crusher and it was a farm wagon in a previous life. So I got down there and found while doing the trans service that it needed exhaust gaskets, Xfer case/trans mount bushing, Xfer case fluid change, and a guibo. As a result I'm doing the CSB as well and have dropped the exhaust, trans/Xfer case cross member, and a whole bunch of other stuff so I'm waiting for parts now. Going to do the initial trans fill now (~4 liters I think) and wait to do the final fill until the rest of the car is put back together. You are right about the seals, I have pictures, they weren't cracked but they were FLAT and hard. The new ones are at least 2mm taller and much more pliable.
BTW, to anyone thinking about an E60/E61... they are the most expensive BMW's I've ever repaired. Parts are more expensive, space is limited on the Xdrive examples, and they are just in general a pain to work on. In almost a year of ownership I've put $4500 in parts on top of the $1200 purchase price. $5700 is a small price really for a VERY well sorted wagon, but it's still taken a lot of time and effort. So just a word of caution. I knew it would need more than usual being it had 181k miles on it at purchase, but it far exceeded the usual ~$2000 in catch-up maintenance/repair usually required to turn a used BMW into a good, "drive anywhere at anytime" daily vehicle. The wife and I love it though. We're certified BMW masochists.
