I didn't vote as I don't think any of them are better than the others in regards to shifting. I have used both Redline D4-ATF and AMSOIL ATF in my Z cars with no difference in quality of shifting. JMHO.

I voted Royal Purple cause I'm using Royal Purple Syncromax in my Z06 now and it has made the shifting a lot smoother. I have also used Redline in my old C5 manual and it worked well too.....

I used the Red Line D4ATF for my first race season, been using AMSOIL ever since.

Not wanting to deviate from what GM recommends or perhaps influence someone to jeopardize their warranty, I voted for GM. I realize, however, there is no "best." FWIW I've used Royal Purple transmission fluid for years with excellent results. Do as I say....not as I do.

I might be missing something here but the manual transmission in our Vettes is a fill for life and requires no fluid change according to the manuals and everything else I have read. Is this really needed, not according to the manufacturer?

If I remember corretly, the Oldsmobile dealership I work in back in 1963, used all 76 products and the oil was purple. We called it Grape Juice. It stained everything. Was that the origin of Royal Purple?
