under the instrument panel to the right of the steering column. The indicator was a small window in the instrument cluster arranged in "L D N R" positions. In 1965, the lever was moved up to the right of the fuel gauge and was a "T" type small silver lever. The quadrant now read "R N D L." Until 1967, the shifter moved through the quadrants in a straight line. From 1967 through 1969, the lever remained in the 1965 position but due to safety concerns, required the driver to move it to the left (it was spring-loaded) to select Reverse and Low. The "T" handle was replaced with a large, mushroomed black plastic knob. Corvair Powerglide was an all-new design, but borrowed a couple small parts from Chevrolet Turboglide and its operating concept is very similar to conventional Chevy Powerglide. Aluminum Powerglide, introduced in the conventional Chevrolet models in 1962 (starting with Chevy II) incorporated many features pioneered by Corvair Powerglide, scaled up slightly for the larger passenger car and light truck lines. The Corvair was originally intended to be only available with Powerglide, but late in its development, a manual transmission was also designed to help lower the base sticker price for its 1960 introduction. The Corvair Powerglide transmission remained largely in its original design throughout the Corvair's production, which ended in May 1969.
