Hi, first off I'm new to the forum and a proud new owner of an 86 5.0 GT. I've had this car for about a week and it runs great, until today I was cruisin around 45 50 and out of nowhere my car starts clunking or banging kind of. It only happens in 1st 2nd and 3rd when i shift into 4th it goes away mostly but not completely. I haven't been able to build up much speed on count of the speed limit and cops are thick here. It only happens in gear and when I put the clutch all the way in it goes away and I can coast in neutral and there is no sound. It's really hard to explain but it's like "tap tap" then a second or two and then another "tap tap". Could it be the clutch or do you guy's think its my tranny. pllllleeeezzzzz my mustang needs your help!!!!
