The T6060 was designed for ATF, nothing else. If you want the best shifting cold or hot, use this and never look back.
Amsoil ATF - requires 1 gallon (4 quarts).
Tried that, it was nudgy when cold but great when hot. When the transmission was warm it was ok. I've tried all the products and did a written check list of my thoughts after each one. The best combination from my results whats the gm fluid with the 1 quart of the syncromesh. I know the GM fluid is probably a relabel from something else but I was pointed to that combination from a fellow on the zr1 forums. I was extremely skeptical at first but I tell you that combination of gm manual transmission and transfer case oil with that 1 quart of gm syncromesh was like heaven. It performed great when cold, warm and hot. warm is daily driving and hot is on track days. I strongly encourage anyone to just try it and I promise they will not look at any other fluids. If you dont like it (which I doubt) you only wasted like $40 on fluids...
