I got a 66 Fairlane 289 3 on the tree. I was driving and shifted into 2nd it popped real loud and wouldnt go. I dropped back to first and reshifted to 2nd and it slid into position but no go. How hard is this to fix? I dont know much about a trans but learn fast? I have a 66 Cruis-o-matic auto but cant find a fly wheel for it. Can i use a c4 plate or not? Im leaning towards changing swapping the cruse o matic into it. Please help.
