BTE Powerglide planetary gear sets - 1.80, 1.98, 1.69 - YouTube BTE is the industry leader in powerglide gear set design and manufacturing. According to Drivetrain.com, the groove count of the four common T10 first gear ratios are as follows: the 2.43 first gear ratio has two grooves, the 2.64 first gear has three, the 3.42 has five and the 2.88 first gear ratio has six. [7] Powerglides are also popular in mud racing and monster truck racing. To make calculating planetary gear ratios as simple as possible, note the number of teeth on the sun and ring gears. 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? Now there are large cubic inch race engines that make good torque and horsepower at higher numbers. Thanks. truck and had the .373. rear end. And its durability allows it to run 100 to 150 races before needing a rebuilding that takes only two hours, Coughlin says. "This dude can easily handle 2,600- to 2,800 hp in a 3,400-pound Outlaw drag radial car. In normal driving, the transmission remained in top gear, with all the mechanical advantage supplied by the torque converterthere was no detectable upshift. MPH. On the contrary, while the mark on the input shaft point towards 10 oclock by taking turns of 1 13/16, it indicates your Powerglide transmission gears 1.82 ratios. Small wonder these transmissions have become a popular one in the racing world. (The shift pattern was PNDLR, eventually revised to the familiar PRNDL.) While the two transmissions are quite different in detailand in costboth the Buick Dynaflow and the Chevy Powerglide were developed by automatic transmission guru O.K.

Only available installed in an ATI transmission. However, the above-mentioned 1.76 and 1.82 are two first-gear ratios in OEM Powerglide. [5] Other Powerglides came with an incompatible 16 spline output shaft.[6]. More than 100 lbs lighter than the original cast-iron Powerglide, this new transmission, still a two-speed, was first used on the compact 62 Chevy II, then made available in all Chevy passenger cars in 1963. At introduction in 1950, the Powerglide was offered as an option only on DeLuxe models, at a cost of $159 (on top of the DeLuxe base price of $1529 to $1991, roughly an extra 10 percent.) Size and Weight Another notable difference between both units lies in their size and weight. We used to run powerglides in the 60's with 4.11's Yeh the 3.73's will be all right just don't expect good gas miliage. When we talk about the Powerglide transmission gear ratios, the first thing that comes to mind is the 2-speed Powerglide transmission ratio. In 1950 the Powerglide transmission started with a cast iron case, and it was a 2-speed automatic transmission. Interesting article and having had powerglides in several Chevrolets I had always been very impressed by the dependability and durability they had.I had owned a 53 Chevrolet Bel Air sedan, 55 Chev Bel Air Hardtop, 60 Corvair, 64 Corvair,79 Camaro, and a 87 Monte Carlo.Never any trouble with any of these.

I have a 68 powerglide I want to find out the ratio. Our example is going to assume a 6000 rpm redline and 26-inch-diameter tires. Now, for the 1.76 ratio, 1 turns should have been made by the mark on the input shaft. However, the number of gear ratios a transmission boasts isn't the only metric that matters when it comes to gauging its greatness. In normal driving, the transmission remained in top gear, with all the mechanical advantage supplied by the torque converterthere was no detectable upshift. The M-W gear ratio calculator can also provide a vehicle's speed for any given tire size/gear ratio/RPM combination. 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.
