Photo below courtesy of ATI Performance Products. 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. The Powerglide automatic transmission loyally served Chevrolet and General Motors for nearly a quarter of a century. A two-speed planetary gearset with a first-gear ratio of 1.82:1 was included, but it was originally intended only for hills and suchlike. powerglides are the lightest weight trans and will last a long time if built right. Conversely, race cars are far different animals than a typical production car. The eight-cylinder engines used a 1.76:1 low gear and 1.00:1 high. Come join the discussion about restoration, builds, performance, modifications, classifieds, troubleshooting, maintenance, and more! Now, don't get me wrong. Low Gear Sets. One notable exception was the export version of the transmission, which offered only the 1.82 ratio and was used by Holden in Australia behind their Australian built 6-cylinder and V8 engines. The input shafts are different lengths also. Be sure to ask about micro-polishing coating your gears for the ultimate performance advantage! On the other hand, for cars that will see any street time at all, a TH400 is a better option. 1 - 12 of 14 items.

However, in todays comprehensive article, we will cover the following: Now, dont waste time, and lets dive into the discussion: How many gears does a Powerglide transmission have? Come join the discussion about performance, modifications, classifieds, troubleshooting, maintenance, and more! But the Powerglide was typicly used with around a 3.36:1.0 rear axle ratio back in the 1960s. Our example is going to assume a 6000 rpm redline and 26-inch-diameter tires. [ (Axle Ratio x Vehicle Speed x Transmission Ratio x 336.13) / Tire Diameter ] = [ (3.73 x 65 x 1.00 x 336.13) / 31 ] = [ 2628 ] Note: 336.13 is used to convert the result to RPM = [63360 inches per mile / (60 minutes per hour x Pi.)] It keeps the car running pretty much but also tends to fail. Cookie Policy. CUT - VASCO - PG SUN / PG OUTPUT, STRAIGHT Just as the Turboglide was eliminated, GM brought out a redesigned second-generation Powerglide for 62 (above) that combined the key features of the Powerglide and Turboglide, including a modern, pressure-cast aluminum housing and a sealed torque converter. If you need any help with going through it, just email me. Different-ratio first-gear sets are now available (through TCI Automotive, JW Performance Transmissions, and others) for the Powerglide transmission. i will run super pro & pro thanks Doug Reply 04-23-2012, 02:43 PM # 2 But since the powerglides have such a low first gear with only 3.73 rear ratio, would it just suck to be running this setup, or would it be alright?

Reverse gear ratio was 1.82-to-1. 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. Engine is putting out about 523 torque at 5000 rpm without nitrous. The planetary gear assembly is the backbone of the entire system. When the Chevrolet Powerglide made its debut in 1950, it was the first automatic transmission intended specifically for the low-priced field. Pontiac 326 Vs Chevy 327 Differences & Similarities. Contact the seller. If the mark on the input shaft turns 1 13/16 turns and is pointing towards 10 oclock, it would be a 1.82 ratio.

The quadrant indicator on Torque-Drive cars was, Park-R-N-Hi-1st. Next, add the two numbers together: The sum of the two gears' teeth equals the number of teeth on the planetary gears connected to the carrier. Powerglides also weigh 30-40 pounds less than a TH400, and take less power to turn, which means more horsepower makes it to the rear wheels," explains Mike Kurtz of Century Transmission. For the 1968 model year, Chevrolet introduced a semi-automatic version of Powerglide marketed under the name Torque-Drive. Use the Choose Your Build table to select the right assembly.
