nuch ss396,

The CY code redesigned Turbo-400 came out in the 68 COPO Novas that were built for Fred Gibb. It was the first of the automatics to be put behind a high horsepower, solid lifter engine, in which the purpose was to get Chevrolet involved in the automatic classes of NHRA drag racing. This run of Novas was built the first 2 weeks of July, which was near the end of the 68 run. Thus, these redesigned transmissions were actually referred to as 69 experimental automatics. The CX code Turbo would replace the CY on October 25, 1968, meaning most, if not all, of the 69 high performance solid lifter cars would have the CX code? The CY transmissions had an 8 bolt flange holding the front pump, which undoubtly would hold true for the CX,as well? One of the main differences between these two transmissions, I think you will find the CX transmission used a little higher stall converter. Ray
