No, a 1993 Chevy automatic transmission will almost certainly *not* fit a 1969 327 SBC (Small Block Chevy). The bolt patterns, bellhousing dimensions, and overall design are completely different between those generations. The 1993 transmission likely uses a different type of bellhousing (likely a more modern electronic controlled unit), and the engine's bellhousing pattern changed significantly between 1969 and 1993. You'd need an adapter, and even then it's highly unlikely to be a straightforward or reliable solution.
To mate a transmission to a 1969 327, you'd need a transmission designed for that era of small block Chevy. Common choices include the TH350, TH400, and Powerglide, depending on the application.
