I run this shit in all my transmissions. doesn't really do much for manual boxes, but it works wonders in worn-out autos.

not claiming it'll "fix" a broken trans, but it definitely does something.

It's indirectly a thing in Canada at some shops that have a minimum purchase if you use a card. All bank cards charge a usage fee typically as a percentage of the purchase. The shop normally absorbs that cost as the price of making it easier for the customer to buy things at the store.
That used to be a factor when cash and personal checks were the norm as payment. But if everyone uses plastic cards, then much of that original incentive is lost and the banks simply are more like parasites than an additional incentive for the customer to buy at that shop. The profit is huge and its why banks and investment houses that have an ownership in the banking system have fantastically wealthy investors.
In america, many places now make the customer pay the cost of using the cards. Most gas stations do in my area. Some like costco don't charge for some brands of cards. Medical firms, most dentists, and even some convenience stores pass the cost on to the consumer. My local pizza shop makes card users pay more because they refuse to lose the percentage fee to some bank that did very little but jewishly sit back and watch the money roll in. When one considers the huge volume of business going on every day with banks getting a percentage of all of that just for the money flowing thru cards, it's more apparent how parasitic the loading fee is upon the system.
I know how credit cards work, just amazes me how businesses pass the cost onto to consumers like that
I guess banks aren't as well regulating in the US as they are in Canada
Seafoam for the throttle and intake actually works well with results. I personally use BG44 for cleaning my fuel system every once in a while and it works wonders. American fuel is surprisingly dirty due to the minimal refinement process and results in dirty injectors, carved valves and cylinders as well. Use that stuff and work your engine every once in a while and I guarantee that it will pay off in the long run.
