I have an automatic 98 1KZ-TE and I’m looking at changing all the fluids. Brought it back from Japan not too long ago. Everything I see looks like it requires D-II fluid. Seems somewhat difficult to get in the states. I see threads elsewhere saying T-IV can be used in place, but I’m skeptical about the viscosity differences. I’ve also seen that D-III was the actual recommendation. So I need some guidance. Any recommendations on more available fluid types?
