Turboglides did come in 283 powered cars starting in '57, not sure when they dropped them, maybe '61. A three speed was never factory installed behind a 283 that I remember but some late 50's pickups came with a 283 and the 4 speed hydro, the sedan deliveries were considered trucks so that's how they were able to use the hydros.
350 transmissions were not introduced until 1969, no three speeds for the 64's, the '65 big cars used the turbo 400 for the first time behind the 396. The turbo 400 was used behind small blocks in '68 big cars and some '68 pickups and of course in Vettes for several years. Ironically the '66 Chevelle 396 auto cars were powerglides.
I'm pretty sure Tarrances car was a three speed.

No documentation for backup but the way I remembered it.
