Welcome to the Q&A Forum

Hi Lucas, If the URL is automatically changing to the non-trailing slash version it sounds like there is already a redirect in place. This is good practice for SEO. Multiple versions of a page (e.g. www,mystite.com, mysite.com, www.mystite.com/, mysite.com/) can split ranking power and lead to lower rankings overall. A 301 redirect transfers the majority of the "link juice" to the page that it is redirecting to. This post on the official Google blog is a great starting point to learn more about trailing slashes and their implications for SEO: http://googlewebmastercentral.blogspot.co.uk/2010/04/to-slash-or-not-to-slash.html
