Welcome to JustAnswer!; my name is Ed.

Disconnect the 2-wire field control connector at your alternator and repeat the same circumstances. Feedback from a bad alternator can induce a false speed signal in the transmission/ engine side of the electrical system, causing exactly the symptoms you've described. If successful, replace the alternator and you'll say wow.
