Thanks for the info and the links. I have gone through all of them and I'm going with the ZF fluid from VW for my 530. I know it's not as cheap as the other stuff but I think it will give me the warm fuzzy feeling knowing that the right stuff is in there. From what I understand ZF builds both BMW and VW-Audi trans and they both use the "life time" fluid. I know in the VW product over time they will have valve body issues if you don't keep them up.
As for my 323 I want to know two things.
1. Does anyone know the best place to buy the Texaco fluid?
2. I there any VW fluid that will work in my trans?
I get a good discount but this stuff is still going to be expensive. I can get the ZF fluid for about $14.00/Lt. If I'm heading down the wrong path with any of these ideas let me know. I have worked in the car biz for years but still trust all of your opinions.
