Visit me at: this video I cover the purpose and operation of the turbine, stator, impeller, and torque converter clutch. Torque Converter Tork Master 3000 Fits GM 1965 to 1991 TH400, 425, 375 and 1968 to 1981 TH350, 375B (not 350C) The Tork Master is BandM's lowest cost performance torque converter. The Tork Master is an excellent all-around performance street converter. The best 'value priced' street converters available, Tork Master converters come with. This transmission does vary in the amount of fluid required, based on certain specifications such as which torque converter is used. That being said, a common fill volume is between 11-12 quarts for a stock transmission. The TH400, or Turbo 400, transmission was a 3 speed automatic that was first produced in 1964.
Our converters are built in houese, each converter is custom built to your application, using the same parts used by the big name converter companies from companies such as Sonnax, Transmission Specialties, TCS, Precision, and others.

Our “Street” converters are based on a stock diameter converter, with internal improvements to the thrust washers/bearings, lockup clutch materials, and in some cases TIG welded fins. These are very reasonably priced converters for near stock applications with a slight increase in stall speed. Available in stall speeds from 1600-2400 rpm.
Our non-billet Street/Strip Converters are typically based on a 9.5″ (245mm) core. Some will be on a 10 or 11″ core depending on your transmission and combo. These are aimed at the 400-600 HP combo where WOT lockup is not required. $550 for non-lockup GM applications and GM lockup applications (200-4R, 700-R4, 4L60E, 4L80E)
This is our Turbo 350, Turbo 400 & Powerglide series converters. Billet cover, TIG welded fins, and anti ballooning plate. Custom built to your application.

Now for our Billet Street/Strip converters. These converters offer a billet front cover with larger lockup disc (when applicable), TIG-welded fins, more aggressive lockup materials, and are good for over 1000 HP. You DO get what you pay for when it comes to converters. There is a reason the billet converter costs 3 times as much as our base line of converters. However, you don’t have to pay a premium for a big name to get excellent quality.
