I usually post on osr but the site is down so forgive my newness and my barging in with a long question...but I'm desperate! I have a 1960 Caddy 62series. It was running perfectly and then problems first I noticed what seemed to be the transmission taking a very long time to automatically shift from between 35/40 mph and 60 mph. When weather was cold it would do it frequently but when weather was nice it would easily reach 60 and then do it only after I had been driving it for about 20-30 minutes. This problem came and went. Then the car just died in traffic but had full electrics...almost as if it ran out of gas. It would continue to do this everytime it was stopped and idling. I changed the fuel pump, rebuilt the carb and put on a new fuel line as the old one was brittle. Now the car will start up and idle perfectly. It progresses up to about 20 mph and then no matter how much gas I give it, won't shift past. The car then starts to power down and dies in about 30 seconds regardless of how fast I'm going. Also the whole time the exhaust is blowing out a thick white smoke tinged with black. The engine is running really hard...almost as if too many rpm's. I don't know what to do next? Head gasket? Manifold leak? Rebuild whole tranny? Carb is set correctly and I've checked the points and timing. Any help you can give me would be much appreciated! Thanks so much! Samantha

These cars (I believe) shift by three controls. A throttle position linkage from carb, a vacuum hose from intake manifold to trans must be intact, and governor in the trans that will force it to upshift, but that doesn't go bad very much, T
