i realize this was mentioned in a previous thread. but i have some questions about it. for one will it wear down on your tranny, i have heard some stories of people shifting with that on differnt cars and it hurting thier transmission. ok and second how do you use it i get the ratcheting forward for up one gear and back to go down a gear but when your on it do you need to take your foot off the gas when you shift or no. and then last does anyone on the forum have it and if so what do you think about it?
