in the older days when dextron and type F (ford) fluids were kings, you could pick up a cheap shift kit and switch from dextron to type f and see a real differencein shift quality. just changing the fluid type made huge differences. this was attributed to the friction coefficient of the of the type f because of this history it makes me wonder about the differences in the shell TF and Mopar atf+4. has anybodyexperienced a difference after changing their fluid?
