Strength and rigidity are the keys to any foundation, which is why J.W. Performance developed the Powerglide transmission Ultra-Cases. Most engine builders would not build a high-horsepower race engine in a stock block, so why build a race Powerglide with a stock case? These all-aluminum Ultra-Cases are the strongest and most rigid foundations available to build your Powerglide with. Designed to be used with the J.W. Performance Ultra-Bells, these cases are loaded with benefits, including improved oil passages, an adjustable trans-brake release, increased material thickness in critical areas, the eliminating of case breakage, and they fit under stock floors. J.W. Performance Ultra-Case Powerglide transmission cases are SFI-certified, so there is no need for an external transmission shield. Made in the USA.
