it's likely because the linkage is not in synch

Discussion summary

c4 trans

The driver has a 1966 Mustang with a C4 automatic transmission taken from a salvage yard. They report the trans will engage reverse and shift from 1st to 2nd but will not go into 3rd. In Drive, selecting 2 does not force a downshift and shifting from 2 back to D does not resume the expected shift; the linkage appears to move through P–R–N–D, and at about 60 mph selecting 2 produces no change.

Reported outcome: The poster did not report a repair or resolution; the problem persisted as described in the thread.
