There is no last word. All three of the above products are great products rated within the top 5 of oils. I cant remeber the line off the top of my head but penzoil also makes a good one.

All the 3 you mentioned have been used by many with varying results. I switched to Amsoil and honestly can't tell much of a noticeable difference. I really don't think any fluids are going to make a drastic difference in shifting improvement.

trans fuild
thanks for the infomation, I will leave the valoline mecon in the trans. on the same subject do any of you blip the throttle when down shift. I have noticed you get a better down shift to second.

I use AMSOIL Torque-Drive Synthetic Transmission Fluid (product code ATG1G) in my daily driver, an 06 CTS-V with the same Tremec six speed as in the Corvette. This fluid does not have any viscosity improvers and will not shear down. Compare that to the factory fill fluid in my CTS-V which sheared down in viscosity to low out of grade in about 10k miles:

Note that I used the AMSOIL ATF for about 7k miles and it did not lose any viscosity during that period. I switched ot the Torque Drive as AMSOIL changed their primary recommendation for the Tremec from the ATF to the Torque Drive. Both are very similar fluids, but I wanted to try the Torque Drive before I started recommending it. For what its worth, I've used the ATF in my Z06 since 2004 without a problem.
