Slick50 is a teflon additive that you have to shake before you pour it into your engine. If you have to shake the suspension to mix it up before pouring it in, guess what happens when it sits in your engine? It settles and clogs up passage ways. Slick50 has also been sued for false advertisement, and unsubstantiated claims. They lost the case, and paid huge fines. Its a complete waste of money, and it doesnt work.

Honda Accord A/T's shift a little harsh, but routine fluid changes keep them as smooth as they are going to get. Stick with Honda ATF especially on the newer years.
