I drained the factory fill from my 09 Z06 and replaced with the RP Syncromax and drove it. It was way worse then the factory fill. Drained it, and replaced with Mobil1 ATF and it appeared to be about the same as the factory fill, maybe a tad better. I've put around 5,000 miles on the car since the fluid change and it's a little better shifting 1-2 & 2-3 but I'm still not happy having to granny shift to keep the nibbles/grinds in check. I get my 56 down off the lift every once and awhile and am surprised how well it shifts(1970 Muncie 4 speed/Hurst shifter). It's stiffer shifting then the Z06's transmission but goes into gear with no syncro nibbles/grinds.
seems not everything gets better as the technology evolves...
