Thanks for the question!

As long as the transmission is not already overfilled, you can add the full 16 oz can directly to the transmission and you don’t have to drain any fluid. It will work to clean sticky residues and condition the transmission fluid for the life of the fluid.

If you’re using it as a pre-flush before changing the fluid, make sure to drive the vehicle for at least 30 miles to circulate the Trans Tune through the system.

Hope that helps and let me know if you have any other questions!

Thanks for the question, David.

In most cases, no, you do not need to remove any transmission fluid before adding Sea Foam Trans Tune. As long as the transmission is not already overfilled, you can add a pint of Trans Tune directly to the transmission fluid. Just follow the directions on the can.

Hi Terri – yes, Trans Tune can be added to CVT transmission fluid as long as the fluid is derived from petroleum (most are).

• If the cause of the shifting delay is buildup in the transmission, Trans Tune can help clean it up and restore smooth shifting. It’s an easy first thing to try.
• If the delay is caused by worn out parts or a mechanical problem, Trans Tune won’t fix it. However, if you try it and it doesn’t help, it does serve to rule out a buildup problem and can be helpful in diagnostics.
• If the issue is severe, we recommend having the vehicle diagnosed by a reputable repair shop.

Thanks for the question, James. You can leave Trans Tune in there for the life of the fluid. Drive at least 20 miles if you’re doing a pre-flush with Trans Tune.
