I asked one of my good friends who knows transmissions better than anyone should and he told me to (for GM transmissions) just use Dextron ATF. The synthetic juice is too slippery and the clutches will not work as well. You may have to change the fluid more frequently as the fluid today has less "good stuff" for our non-lockup convertors. Get a good cooler and pay attention to your fluid.
