I don't know if that is the vintage C4 or C6 transmission, but maybe just a modulator valve if you're lucky.
 
The C-4 arrived in 1964 and like the Cruise-O-Matic was a hydraulically controlled rear-wheel-drive automatic. It was commonly matched with six-cylinder and small-block V-8 engines. The C-4 differed from the Cruise-O-Matic with its three-piece case consisting of the main case, bell housing and tail housing. Although it used a Simpson planetary gear set like the Cruise-O-Matic, the C-4 was considerably lighter. While the Cruise-O-Matic featured a three-bolt bell housing pattern, the C-4 had a five-bolt bell housing pattern in 1964 and six-bolt pattern starting in 1965. The C-4’s bolt patterns allowed the transmission to be easily adapted to many different engines. The C-4 also featured two dipstick variations: The dipstick in the case for passenger cars and the dipstick fitted directly in the transmission pan for trucks.

64 TBirds did NOT have a C-4 or a C-6. It was a Medium case Cruise o matic. The shift linkages wore out often. I would check (and you have to get under the car) to see it it is actually shifting into Drive. (It could be so worn or out of adjustment that it is not). The wear is usually in the steering column, and the TBird supply houses have repair kits for that. (Contact The Bird Nest, or Concurs, etc).
 
Good clarification - his complaint was not getting into "High", apparently the car does go into "Drive"
