I recently purchased a 87 GN with 87k miles on it. It's bone stock including the trany and d5 converter. The car shifts hard but has a real fast knocking sound coming from underneath the vehicle. It DOES not sound like a rod. Do converters make noise when they are getting ready to go out?
BTW/ the driver side header is cracked but this sound doesn't sound like an exhaust leak.
Any suggestions?
