I have a 1953 Buick Special convertible with manual transmission. I've had it since 1997. It has always been "funny" to shift up from 1st to 2nd, and downshift from 3rd to 2nd. Over time, I find that in cold weather (below 60 degrees) I have much less trouble shifting. I have bought a "rebuilt" transmission and had it put in, but have the same trouble as my original transmission. I had the original transmission torn apart, and I have been told it needs synchro gears for 2nd and 3rd (I believe). I have not been able to find the gears anywhere. Does anyone know where I can locate the gears? My goal is to have a smooth shifting Buick, as I believe it should be. I have had all the bushing replaced in the linkages, etc. Thanks!
