I have a transmission question, I hope that this is the right place. I have a 95 F150 with the 6 cylinder and 5 speed standard tranny. My 1st and 2nd gears went out. Clutch seems to be fine and I've been able to still drive it a little bit, having to start out in 3rd gear. Is it possible that replacing the synchro unit on top would correct this or am I looking at a complete rebuild? Since this is in survival category, I'll let you know this is my BOV, so I need to get this fixed. Thanks
