Hey everyone! I have a 1957 Cadillac Sedan DeVille with the 365 in it. Recently, we have had some issues shifting from 2nd to 3rd. The rpms have to get way up there before it shifts. We have done some adjusting to the TV rod with no luck. As we drive it longer, it starts to shift better. Someone recommended we put some LucasOil Transmission Fix in it. That is one of the problems with the shifting but we have another, stranger issue with shifting. If we are driving it a little harder, when it shifts from 2nd to 3rd, the engine momentarily cuts out a couple times after the shift. Any help would be appreciated. Thanks! Dan
