I have read many articles on transmission fuid both in this forum and outside this forum.

Now I am looking for advice form experience;

recommended to stay away from syn. in the primary. tends to cause the clutch to slip. seems like what is being recommended now for the primary is Auto. trans. fluid

I just go with good ole Revtech Tranny fluid and RevTech primary fluid. Never and issue with either one. Tried Auto Transmission fluid in primary once and had no issues, but saw no gains either.

I would stay away from syn on the primary side.

I also make sure I change it quite often. It is cheap and tranny only take 20 oz. and primary 32 oz. Figure it is better to change and spend 10 bucks then push the service dates out and risk anything.

I also run the Spectro. Have found I can find Neutral easier after switching to it from Mobile 1.
