Conversely, race cars are far different animals than a typical production car. In race cars, compared to a Powerglide a TH400 is better suited for cars with large tires and taller rearend gearing. The OEM powerglide was manufactured with two first gear ratios - 1.76 and 1.82. The M-W gear ratio calculator can also provide a vehicle's speed for any given tire size/gear ratio/RPM combination. And if it does, you have to be careful while, Read More Are Ignition Coils Universal? 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. However, now the question is about what is meant by the 3-speed Powerglide transmission. 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? Meanwhile, the rear axle ratio was reduced from 4.11:1 to 3.55:1 to manage driveline noise and harshness. Are you looking TCI Auto Gear Ratios? The 1.82 (6-cylinder) had a bluish color or dark. 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.) 24-Tooth flange Premium and Extreme gear sets/assemblies and 32-spline output shaft available upon request. Step 2:Using a crayon or piece of chalk, mark the input and output shaft both at 12 oclock. TH400 has a 32-spline output shaft. Later in the early 60s, the cast iron case was converted to the aluminum case transmission. The Aluminium Powerglide, and Tempestorque was used from 1962 until it was replaced with the Turbo-Hydramatic series of transmission in 1973. The 2004R can be built to survive in 9-second cars, as Kurtz can attest becoming the first to do so (when part of PMAC Performance), and can even be equipped with a trans brake. 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. Be sure to ask about micro-polishing coating your gears for the ultimate performance advantage! Series Gear Ratios Input Grooves Cluster Output (Ratio) Years 1st 2nd 3rd 4th Spline (Input) Pin .

Watch the video to learn how easy it is to level up an existing planetary assembly or build from scratch in the gear ratio of your choice. [7] Powerglides are also popular in mud racing and monster truck racing. For over 40 years Transmission Specialties has been the trusted name in the performance automatic transmission industry. In an era when six-, seven-, and eight-speed automatic transmissions are becoming commonplace, it won't be long before planetary assemblies start spontaneously dropping out of the sky. Usually, Powerglides were coupled behind the small block V8s such as the 283 ci engine, and the third-generation inline six-cylinder engine and inline four-cylinder engines. Using the shifter, the rider chooses the speed in 3 gear transmission. Therefore for maximum drag racing applications, the 1.82 setting is not perfect. Gear Ratio Calculator. The transmission was simple and very durable, which satisfied customers. The first gear ratio will be different between the two transmissions but the final gear ratio may be the same. 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. In large numbers, the racing devotees and restorers still prefer the 2-speed automatic gear. truck and had the .373. rear end. It's pretty much the baddest of the bad," says Mike.

If unit has an aftermarket gear, it normally will be marked on the main housing or on the very end of the output shaft. The 1.82 gear set is not suitable for most drag racing applications as its power limit is no more than ~ 550 HP engines in even lightweight cars. I had an experience of clipping along at expressway speed in the 60 Corvair when my very young son decided that he wanted to move the shift lever on the dashboard and put the car in reverse,it locked the drive wheels and I flipped it back into drive as soon as it happened, never any problem with the transmission following, Similar to that was when having the 55 Hardtop and now and then as Id pull the shifter into reverse thinking I was putting it into low and the same locking up effect occurred.
