Can I add Trans Tune with other transmission additive? [SOLVED]

Can I add Trans Tune if already added Lucas in my car’s transmission fluid? If yes, can I leave it in for 30,000 miles? I recently changed my transmission fluid.

I am using a Lexus Ls 430.

Good question, Munawar.

Trans Tune is safe to mix with other transmission additives, so you can add it to your transmission fluid even if the Lucas additive is already in there.

Yes, you can leave it in there for 30,000 miles. It will work to condition the fluid as long as it’s in there. No need to change it.

Hope that helps!
