John, The break is generally between 1965 and 1966, for the overwhelming majority. There are some documented 1966 A-Bodies with 1965 parts that were built out early in the 1966 model year. The 1965 727 B and C Body transmissions (popular for B-Body applications) will be readily identified as having all of the following features... 1. Cast aluminum case. 2. 13/16" cable shift hole above the driver's side front corner of the transmission oil pan rail. The hole may have a cable in it, and may or may not have a 2" diameter cable adjusting flange with a 5/16"-18 lock bolt. 3. 5 bolt cover on the bottom of the tailshaft housing with a 15/32" hole (or a cable) facing the driver's side of the car. If the cover is missing, you will be able to see the 5 holes, the irregularly shaped gasket surface, and the internal workings of the park lock assembly. (Note: Removing the 5 bolt cover with the cable installed can result in damaged parts). 4. The slip-spline output shaft. Earlier 727 transmissions will have a round flange that mates to the ball and trunnion joint. Imperial transmissions of this vintage will have a companion flange that accepts a u-joint, the flange looking much like the one on most rear axles. Threads on the end of the output shaft indicate one of these transmissions with the mating flange removed. Almost any slip-spline transmission without features 1 and 2 is a '66-later piece.

I have the thing out where it's easy to inspect but it's been so long since I've seen a pushbutton type out I've kinda forgotten. I realize the splined output shaft is a given but that really doesn't narrow it down much since everything I've got has splines. Is there a casting or model number on it some- where as well - that could be used as a cross reference? I've often noticed a lot of transmission parts seem to use 1967 as some sort of timeline/parts distinction what's the significance or change that occured then? Thanks so much for your help thus far...........
