For the 1968 model year, Chevrolet introduced a semi-automatic version of Powerglide marketed under the name Torque-Drive. Limited quantities - available while supplies last. 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. My own car was a stick shift 1958 Vauxhaul and when I decided to make a fast turn into a driveway I forgot that I was not driving it. Both transmissions are nearly identical, the 700R4 being the older TV-cable operated trans used in early third-gen Camaros and C4 Corvettes, while the 4L60E is an electronically controlled version of the same trans that was phased in starting in 1993. Automatic Transmission Gears, Planetary Gear Sets, 1.80:1 First Gear Ratio, 1.00:1 Second Gear, Long Style 27-spline Output Shaft, GM, Powerglide, Kit Part Number: FTI-F2540L Not Yet Reviewed It's pretty much the baddest of the bad," says Mike. Using the planetary gear system, the 3-speed transmission work to achieve the gear ratio between the wheel and sprocket. 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. [7] Powerglides are also popular in mud racing and monster truck racing. 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. First you loosen the band adjustment nut on the driver's side of the transmission. The heart of the first-generation Powerglide was its torque converter (above). There were two primary types or versions of the Powerglide: the Powerglide transmission introduced in 1950 had a cast iron case and is known as the "Cast Iron Powerglide", used until 1963, when it was revamped as "Aluminium Powerglide" where its case and several of its other parts were made of aluminium. And I have no clue what torque converter to use, can anyone help? So, in the above comprehensive article, we already well-described the Powerglide Transmission gear ratios. Stop worrying about input shaft failure when running the Powerglide in the most extreme applications. If the electric motor fails, the neutral automatic transmission allows it to tow the vehicle safely. "What Ratio is Your Powerglide, 1.76 or 1.82?" . Also, the input shafts mark should point to 9 oclock. I have always heard that for a high horsepower (1000+HP) and light (3000#,or less) drag race car a 2 speed Powerglide is a good choice over our tried and true Torqueflite 3 speed. Actually, no Powerglide was available in 3-speed. That got largely fixed after a couple of years. Did they offer two different ratios? TSI has pioneered much of the technology that is now commonplace in the transmission marketplace. Generally a.c. cars had a lower gear ratio. 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. Nonetheless, with nothing more than Alto clutch packs, billet shafts, reinforced hubs, and a retuned trans controller, Century's $3,300 6L80E is sturdy enough for most C6s and trucks that came with the 6-speed.

However, the above-mentioned 1.76 and 1.82 are two first-gear ratios in OEM Powerglide. On the other hand, the stronger gear ratio is 1.76. Ron Most likely I have a 1.82 It's actually 1.76 and 1.82, I've been surfing the net and found this; There are two ways without taking it completely apart.The input shaft can be pulled out and measured. The constants in decoding the trans ID number are the date the transmission was produced. The mark on the input shaft should have made 1 3/4 turns and be pointing to 9 oclock if it is a 1.76 ratio. This car has a 355 in it. 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. Opinions please.thanks. originally a 3-speed. The answer is identifying the gear ratio is quite simple. $349, Helical & Straight Cut Super Vasco Set Gears, OPTION: 1.82 ALUMINUM CARRIER AND GUN DRILLED OUTPUT, Powerglide Gear Sets for 2.08 & 2.18 Ratios, Powerglide And this gear set features heavier-duty gears and a machined steel carrier. The eight-cylinder engines used a 1.76:1 low gear and 1.00:1 high. The 1964-1965 Corvair had a 3.20:1 first gear, and the '66-up had a 3.11:1 first gear (along with different ratios for the other gears). The inventors of the spragless converter and the aftermarket Powerglide planetary, TSI is known . When introduced on upper-level Chevrolet models in 1950, the Powerglide represented the first automatic transmission offered in a low-priced automobile; in contrast, Ford did not offer their automatic transmission until 1951, while Plymouth car buyers had to wait until 1954. Most of the V8/Powerglide transmissions came with the 1.76 gear set. Never any leaks from these either. GM Powerglide Planetary Gearset 1.76 Ratio un-raced Transmission **Free Shipping. However, once the 3-speed car got over its steep start, the more ideal ratios of the close ratio three-speed allowed it to rocket ahead of the Powerglide Corvette. Easily the transmissions are interchangeable. Your email address will not be published. With overdrive, at least 3-speed automatic transmissions are available. Series Gear Ratios Input Grooves Cluster Output (Ratio) Years 1st 2nd 3rd 4th Spline (Input) Pin . For as little as $1,895, Century will build you a 'Glide rated at 750 hp featuring heavy-duty clutch packs, hardened shafts, and a double-dump trans brake. But as stated you will need to axle code 2-3 letter suffix code or you can open the rear and check the pinion head it will also have the ratio stamped into it by listing the ring tooth count and the pinion tooth count and part number of the pinion gear plus the date usually. 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. Shim Kit, Powerglide Heavy Duty In 1969, the three-speed Turbo Hydramatic 350 (THM350) was introduced as a light-duty companion to the Turbo-Hydramatic 400, and made available on virtually all Chevrolet cars and trucks with six-cylinder or small and medium-sized V8 engines, as well as intermediate sized cars of other GM divisions.[2]. "Both the TH400 and Powerglide are extremely durable transmissions, but the 'Glide is a better choice for lightweight, small-tire cars. SUPERSET - ALUMINUM REVERSE RING GEAR FOR 3 REVERSE CLUTCHES, 1.76 GEARS WITH NEW 4340 BOLT-TOGETHER OUTPUT & CARRIER with 1.76 OEM flange & reverse If you install the Turbo Hydro trans, you could easilly switch to a 3.08 rear end (or even numericly lower) for a lower cruising speed. A chrome badge on the deck lid proudly proclaimed POWER GLIDE, and to compensate for the lack of torque multiplication, Powerglide cars got a slightly larger six-cylinder engine (235 vs. 216.5 cubic inches) with hydraulic valve lifters and 105 hp rather than the standard 90 hp. Hotrodding is much more than just owning a hotrodIt is a state of mind! CUT - VASCO, STRAIGHT It keeps the car running pretty much but also tends to fail. Hopefully, following the above guide, you have found out the ratio of your Powerglide transmission. Holden vehicles fitted with Chevrolet V8 engines used the 1.76 ratio gear-set. 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. It is also possible to purchase all the parts needed to build an Aluminium Powerglide from scratch from most racing parts vendors. Reverse gear ratio was 1.82-to-1. Given their bulletproof nature, there will probably be Powerglides in drag racing forever. [5] Other Powerglides came with an incompatible 16 spline output shaft.[6]. Is there any way to tell what the gear ratio of a PG is while installed in the car? yeah, i just figured whatever will work, probably go with the 1.82. the 1.82 gear ratio is weaker of the 2 factory gear ratios. It is quite easy if the units are 1.76 or 1.82 ratio. With a higher stall converter, the ratio can be smaller, making a rear gear able to be a higher gear for more top end. Torque-Drive was only offered on low-horsepower engines for Camaro and Nova. What is the strongest GM automatic transmission? Its more hefty build can be tied to its 236 lbs and a length of 26.4. My dad would have skinned me. The 1953 and later units when in "Drive" started in low and automatically up shifted to high at a speed determined by the throttle opening. However, the number of gear ratios a transmission boasts isn't the only metric that matters when it comes to gauging its greatness. The big difference is the first-gear ratio. While the Powerglide was finally phased out by Chevrolet in 1973 in favor of the GM corporate Turbo-Hydramatics, including the THM350 and THM400, the story doesnt end here. First locate your current gear ratio and tire diameter and then find your approximate RPM at 65 MPH, then reference your new tire diameter with your desired RPM to find the new gear ratio needed. Given the final axle ratio of 3.08:1 in each car, the overall ratio drops to 2.156:1. BTW the car ran a 12.40 @ 120 MPH on Nitto Drag radials with a 2.7 60' time. Is the Chevy 402 a Good Motor? The Torrington in the 1.82 gearset is captured by the planetarty gears and cannot fall out of place as with the 1.76 Torrington. Again, the overall first-gear ratio with the TH400 and 4.10:1 rear gear would be 10.168:1. This calculator will help your hot rod or street machine get to the next level without red-lining your engine. CUT - VASCO - SG2 SUN / PG OUT, STRAIGHT In this gear system, the sun gear remains fixed during the planet carriers rotation. A turbo 350 is all you need and is lighter than a 400 trans. The Powerglide is a two-speed automatic transmission designed by General Motors. Alternatively, the 4L60E weighs 150 lbs (without fluid) and it has a length of 23.5. defenitly less efficient. I couldn't tell any difference in the engine rpm's. 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. 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? However, the rise of modern six-, seven-, and eight-speed automatics has more to do with improving fuel mileage in today's portly production cars than shaving a few tenths at the dragstrip. 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. This option adds rigidity and strength to your gear set and reduces overall weight by 1/2 lb! A 3.36 rear axle gear ratio would be more livable [3.36 x 2.87 = 9.64]. From the factory, a Powerglide transmission has either a 1.76:1 or 1.82:1 first gear. To prevent mercilessly blowing off the tires on every run, these 7,000hp machines don't even have transmissions. What Is the SBC Header Bolt Torque? 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. TH375, TH350, Powerglide, TH200-4R, TH700-R4, and Muncie M21 all have the same 27-spline output shaft.

I thing drag racers love them as they have ONE gearchange per run. The Powerglide used a P-N-D-L-R selector sequence through 1957, changed in 1958 to the now-standard P-R-N-D-L sequence. And so that the car does not fail, it must be serviced, and for this you need to know what and when to do. Its bulletproof, simple and easy to customize, he says. The eight-cylinders had a 1.76:1 reverse gear. $349 plus parts mentioned. ratio You forgot 3.55 on the 12 bolt too and the 3.90. 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. In these types of applications, a Powerglide is the ultimate in consistency as well. Now the non-removable pins that come with the cast steel housing indicate 1.76 ratios. 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. The 1.82 gear ratio or gear sets power limit is up to 550 HP engines. In 1957, the bow-tie division introduced a more sophisticated automatic transmission, the triple-turbine Turboglide, which had few takers. Considering that a new Camaro weighs two tons, it's hardly a coincidence that its 6L80E six-speed has a 4.03:1 First gear ratio. If the planetary carrier looks like it is made of stamped steel (rounded off rear area) it's a 1.82. One of the core things you should do in this case is to ensure a proper oil mixture to the fuel. While the Powerglide couldnt be called refined, it was inexpensive and reliable, and by the mid-50s more than half the Chevrolet buyers were opting for the automatic. Includes billet aluminum carrier & gun drilled output shaft. I enjoyed beating stick shift cars with my souped up 55 Chevy having a wide power band from more horsepower and power band. Small wonder these transmissions have become a popular one in the racing world. Here is a down-and-dirty way of picking the best gearing for a particular car from three choices: 3.07:1 final drive with a wide-ratio transmission, a 3.07:1 final drive with a close-ratio transmission, and a 3.36:1 final drive with a close-ratio transmission. More automatic transmissions like 5, 6 or even 7 will come soon. Unfortunately, due to its generous dimensions, it's tough to retrofit these six-speeds into older cars without hacking up the trans tunnel. Join now! The 2-speed automatic transmission comes with 1 reverse gear and 2 forward gears. ATTENTION TO RIGHT HOLDERS! The most extreme example is in NHRA Top Fuel and Funny Car. The TH350 was introduced in 1969 as a replacement to the Powerglide 2 speed automatic transmission. On this Wikipedia the language links are at the top of the page across from the article title.

Never and damages to the durable transmission. Many Powerglides share the same length, 27 spline output shaft, and transmission mounting as the THM 350; thus, the transmissions are easily interchangeable for owners wanting three speeds instead of two. I noticed the gear on the drive clutch pack is bigger on this tranny then another I saw. 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. 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. 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. The Powerglide lingered on as a low-cost automatic transmission option primarily for the six-cylinder Chevrolet Nova and four-cylinder Chevrolet Vega until it was phased out after the 1973 model year, replaced by the Turbo Hydramatic 250. The eight-cylinder engines used a 1.76:1 low gear and 1.00:1 high. Come join the discussion about performance, builds, restoration, modifications, classifieds, troubleshooting, reviews, and more!
