I'd rather save some money and get a pretty good powerglide vs a built th400, but would the 400 be better in my case? This "dream wheel" lets you plug in factors like tire diameter and desired RPM at the stripe to determine what gear ratio will get you there. Save yourself the headache and let us figure out your ring-and-pinion gear ratio! For example, if the sun gear has 20 teeth and the ring gear has 60 . I have a 68 powerglide I want to find out the ratio. around 850ish hp, but will be higher in the future. The answer is identifying the gear ratio is quite simple. Use the Choose Your Build table to select the right assembly. Sort By: Also, the semi-automatic gear shifting possibility and neutral position are available in it. Join now! Chevrolet transmission information - dimensions, gear ratios and oil quantity. For a better experience, please enable JavaScript in your browser before proceeding. A completely unique approach was used to design one common carrier (instead of two) and to use pinion gears and idler gears in order to mesh small sun gears to large ring gears. The constants in decoding the trans ID number are the date the transmission was produced. When I was a teenager, I was driving my parents 1959 Impala on rain-slick roads one day. Then, change Richmond's performance gear ratios and beat your best time! For the 1968 model year, Chevrolet introduced a semi-automatic version of Powerglide marketed under the name Torque-Drive. 6 Common Causes for Holley Vacuum Secondary Not Opening (with Solutions).

Holden vehicles fitted with Chevrolet V8 engines used the 1.76 ratio gear-set. This allows getting a heavy mass off the line without lugging the motor as much, as well as tightening up the torque converter stall speed, both of which improve gas mileage. Although it is a very old design, the Powerglide still has a strong following in drag racing due to its strength and simplicity. This is a problem when converting the '54 rear ends to 3.55:1 using the ring and pinion sets available from Patrick's. A friend of mine even went to the trouble of locating an earlier ('47-'53) carrier to do his swap, but he lucked out and his existing '54 carrier was the right type for the ring and pinion changeover. 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. 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. On the other hand, for cars that will see any street time at all, a TH400 is a better option. To make calculating planetary gear ratios as simple as possible, note the number of teeth on the sun and ring gears. Eight-cylinders had a 1.76:1 reverse gear ratio. Variants of the Powerglide were also used in the Corvair and Pontiac Tempest transaxles, and one of the final applications was in the subcompact 1971 Chevrolet Vega.

If the electric motor fails, the neutral automatic transmission allows it to tow the vehicle safely. What is the gear ratio of a 2 speed Powerglide? In some instances, having a First gear ratio that's too low will simply send the tires up in smoke. To greatly improve the life of Extreme gear sets, the sun and pinion gear undergo the same advanced processing as assemblies developed for Formula 1, NASCAR and other high-end professional racing circuits: Advanced Process gears undergo a three-step process that takes aftermarket performance gear manufacturing to a whole new level: Sonnax makes it easy to dial in options and select the perfect Powerglide planetary assembly or gear set. 61e (4.26) with 3.27 axle = 13.9:1 overall first gear ratio 61L (3.65) with 3.898 axle = 14.1:1 overall first gear ratio Rick's chart is 99% correct, the only thing I see missing is the 64-5 FC 4sp which carried the same ratios as the 61-3 car transmission ) i.e. Build with a torque converter lock, a 27-spline input/output shaft, 11-quart fuel capacity, a case length of about 27" and a width of about 19", and an aluminum outer casing, its torque capacity outdoes even the reliable 700R4 of the time. Its gear ratios are: 1st gear: 2.74 2nd gear: 1.57 3rd gear: 1 4th gear: .67 For V-8 models, the automatic had a 1.76-to-1 first gear and 1.00-to-1 second gear ratio. There was no sump or pan on the bottom, and instead of a one-piece aluminum case, the Powerglide used a collection of cast-iron housings that bolted together. 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. How Do You Identify The 2 Speed Powerglide Gear Ratios? Someone feel free to jump in here if I am off base. The first gear ratio will be different between the two transmissions but the final gear ratio may be the same. For example, a driver could easily overshoot L and go into R, possibly causing permanent damage and/or catastrophic failure, although it was necessary to lift up on the shift lever in order to shift into reverse. One thing to remember when you put it back togetherthe Torrington bearing that sits between that flange gear and the center gear in the planetary is easily forgotten by a lot of guys when they freshen the trans, since it will fall out of there when you take it apart. The reverse gear ratio was 1.76-to-1. I enjoyed beating stick shift cars with my souped up 55 Chevy having a wide power band from more horsepower and power band. Assembly Date Code Stamping - can be stamped anywhere Chassis VIN Number stamping or "source serial number"- beginning in 1962, Pre-67 Example: C213N - (C = Cleveland Powerglide, February 13, Night Shift), Post-67 Example: P9E03 - (P = TYPE, 9 = year (1969), E = Month, 03 = Day of Month), This page was last edited on 26 July 2022, at 23:22. 275 radials.

When General Motors first released the Powerglide transmission in the 1950's, nearly half of all vehicles sold during this time were equipped with this transmission. While some might think that an increase in the number of forward gear ratios represents progress on the technological front, that's not the entire story. Meanwhile the 'Glide's taller 1.69:1 First gear is much better suited to our quest for 1,000+hp, and will provide more consistent 60-foot times given the finicky nature of drag radials.

Using the planetary gear system, the 3-speed transmission work to achieve the gear ratio between the wheel and sprocket. The Sonnax 1.58 delivers tunable control for Powerglides right at the start, when traction can make or break a race. The main hiccup on the 4L60E is its gear ratios 3.06 in first and 1.62 in second, which meant you were getting a massive amount of torque in first gear, before dropping down to about half that power in second. Is the Chevy 402 a Good Motor? Actually, no Powerglide was available in 3-speed. Meanwhile, the rear axle ratio was reduced from 4.11:1 to 3.55:1 to manage driveline noise and harshness. Thanks. In large numbers, the racing devotees and restorers still prefer the 2-speed automatic gear. I never tried that again. It is a 1.76 as mentioned, since the 1.82 has 23 teeth on the flange gear. 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. I am thinking about going to 28" tall slicks under the car. Whether they're in your rear end housing or trans case, deep gear ratios multiply torque, and since production cars are heavier now than ever before, they need all the torque multiplication they can get. . As a result, the unit was quite heavy at better than 240 lbs, and there were a number of gasketed joints with the potential for fluid leaks. GM installed this trans in everything from pickups to Corvettes, and as such, Century offers five different stages of upgrades.
