Chassis Control System Error: What Causes This Problem And How To Fix It? They were introduced in Buicks and Cadillacs the previous year. From the factory, a Powerglide transmission has either a 1.76:1 or 1.82:1 first gear. Powerglides were used extensively on Pontiacs produced for the Canadian market with Chevrolet powertrains. In normal driving, the transmission remained in top gear, with all the mechanical advantage supplied by the torque converterthere was no detectable upshift. For example, if the sun gear has 20 teeth and the ring gear has 60 . Currently Robert Campisi from Australia holds the World Record for the fastest run using a Powerglide transmission, clocking 5.95s at 260mph in his Twin Turbo Ford Mustang in September 2011.[8]. .

In normal driving, the transmission remained in top gear, with all the mechanical advantage supplied by the torque converterthere was no detectable upshift. In fact, the earliest Chevrolet technical literature often referred to the unit as a torque converter transmission rather than the more simple and familiar automatic. The original 1950 design employed a five-element, bolt-together converter that provided a torque multiplication factor of 2.20:1. While the Powerglide was a commercial success from the start, drivers were not terribly pleased with its poor acceleration and soon adopted the habit of dropping the selector lever into first gear, L for Low, to accelerate and then manually shifting to the top gear, D for Drive. Apparently, the transmission wasn't very durable, since it depended on the driver's ability to shift between gears in a way that wouldn't damage the unit.

Sonnax high performance products meet the toughest challenges faced by hard-working, daily-use drivetrains as well as racing units going all-out on the street or track. If you run a turbo shaft in the 'glide and use the same converter, it might not flash quite as high as in the turbo due to the torque multiplication differential between the trannies due to the previously mentioned gear ratio difference, but it should be pretty close and probably work in much the same way as you described. A relatively narrow-tired car (each rear tire measures 11 inches or less across the tread) has a certain maximum starting-line ratio to be used based upon the weight of the car and the stroke of the engine.
