View Full Version : Transmission Knock in 2007 SS

My boat has done this from the begining. I don't know why, but at idle neutral position the crusader 5.7L trans makes a weird knocking noise. It goes away after you put it in gear, but annoying at idle, sometimes it does this and other times not. Anybody have a clue or experience the same thing.

What sort of fluid are you using?

I have heard that in some of them changing from an ATF to i believe a motor oil can quiet the transmissions down.
