Can you add Trans Tune to new transmission fluid? [SOLVED]

My vehicle is a 2009 Hyundai Tucson. Had the transmission fluid replaced about 8 weeks ago but I’d like to try Trans Tune to help improve shifting. Is it OK to add Trans Tune to newer fluid?

Thanks for the question Jane. Even though Trans Tune is often used as a fluid pre-flush, you can add Trans Tune to ATF (automatic transmission fluid) at any time and leave it in for the remaining life of the fluid, even when the fluid is new.
