Transmission fluid for 986 5 speed - redline?

[jaykay]

I promised to report back on Miller from another for thread I believe. I do find it a bit notchy. I am working with a six speed which is well seems to be inherently notchy anyway I'll go back to the Porsche fluid at some point and report back. Just wondering if there's a difference in formulation for the six speed versus five speed

Miller was put in as a substitute for the Porsche fluid without my knowledge or without my consent
