These transmissions were mounted behind the 315HP 348ci engine in full size Chevys (4500 lbs.) and survived. These are most like a present day hydraulic version of the AUDI/VW DSG dual clutch manual tranny in that more that one 'gear' is engaged at the same time: DSG- 2 gears, Turboglide- 3 gears.

The Turboglide as well as most of the other GM automatics of the time were phased out in favor of the TH350 and TH400 to reduce complexity and cost and to improve performance and reliability/durability.
