Anyone ever read the can?

I used the Seafoam trans tune recently in a problem car. Can said toss it in, drive around for a little, then remove it. I drove about a week to remove any varnish etc. Then pan dropped, replaced the filter, refilled starting with one quart of Lucas trans stop slip, then the rest regular dex III or whatever the normal non VI is.

Trans is kickin butt so far. Been about 5k miles. Additives aren't an answer for all issues, but sometimes they can help out.
