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. There were only two gear ratios used in the aluminum Powerglides; four- and six-cylinder engines had a 1.82:1 low gear with a 1.00:1 high; reverse gear was 1.82:1. How much horsepower can a Powerglide handle? The transmission was simple and very durable, which satisfied customers. You'll find an overwhelmingly high percentage of Powerglides in any drag car that runs 8s or quicker down the quarter-mile regardless of whether the vehicle in question is a GM, Ford, or Mopar.

The earlier sequence had been criticized on safety grounds for placing reverse after a forward gear, instead of having neutral between reverse and the forward ranges. Compare this to a TH350. 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. Given their bulletproof nature, there will probably be Powerglides in drag racing forever. The bracket racer has a choice from two gear ratios from the factory 1.76 and 1.82. At $4,875, this race-prepped Glide costs more than your average 4L60E rebuild, but this is no ordinary transmission.

Come join the discussion about performance, builds, restoration, modifications, classifieds, troubleshooting, reviews, and more! 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. In fact, a Powerglide can weigh less than a standard manual transmission, provide a direct-drive feel with minimal slippage at the torque converter (or none at all with direct drive), and maintain a relatively low rotating mass. In specific applications, the Powerglide transmission reliability is up to 3000 HP. By continuing to use our site, you agree to their use. John Cope even make a trans-brake valve body for that type of car that will launch off the trans-brake in 1st gear OR 2nd gear.

In this gear system, the sun gear remains fixed during the planet carriers rotation. is a 1.82 ratio. The conventional procedure for selecting gear ratios is to pick ratios that run the engine rpm to redline at the end of the medium and longest straights, and pick the lower gear ratios to minimize the rev drop at each shift. The eight-cylinder engines used a 1.76:1 low gear and 1.00:1 high. Again, the overall first-gear ratio with the TH400 and 4.10:1 rear gear would be 10.168:1. I would say with a glide you have 2.73 or 3.07 ratio.
