Hello.

Ford only put the GT package on 'A' code and 'K' code cars in 65/66. An 'A' code car could have any transmission, although, I've never seen a car that was a real-live factory GT that came with the three speed manual. In 65, all K codes had the 4-speed top-loader. In 66, the C4 automatic was also available on the 'K' codes, but the C4 that it got had some internal differences from the other C4s, so, if the GT in question is an 'A' code it could have anything for a
tranny, if it's a 65 K code, it has a top-loader, and, if it's a 66 K code it could have a top-loader or a C4 automatic, although the automatic K codes were extremely rare.
