High Quality Content by WIKIPEDIA articles! Chevrolet Corvair Powerglide is a two-speed automatic transmission designed specially for the then all-new 1960 Chevrolet Corvair compact car that emerged in the fall of 1959 as Chevrolet`s competitor in the then booming small car market. The Corvair was powered by a six-cylinder rear engine that necessitated a specially designed transaxle. Corvair Powerglide took the principles of the standard Chevrolet Powerglide and modified them to suit the rear mounted powertrain location of the new Corvair. The Corvair used the Powerglide for all 10 years it was produced; from 1961 to 1963, Pontiac used a modified version of Corvair Powerglide it called `TempesTorque` for its front-engine, rear-transaxle Tempest, LeMans and Tempest LeMans cars.
