Ultracase JW Performance Ultra Case
Powerglide JW Ultra-Case High Performance and Racing Powerglide
Transmission Case SFI Approved
The Ultra Case is the foundation of the JW Performance Automatic Transmissions Ultra
Component product line. The JW Ultracase is a SFI certified transmission case that
replaces the weak stock case on Powerglide transmissions. The original stock powerglide
case was never intended to handle the horsepower and torque levels of modern high
performance and racing engines. In addition, modern racing transmissions run far higher
oil pressures than the stock case was designed for. The stock case can deflect, distort
and break in modern performance and racing automatic transmissions.
The all aluminum JW Ultra Case, JW 92310, is the strongest and most
rigid foundation available for the Powerglide transmission. Designed to be used with the
JW Ultra Bell, the ultra case is loaded with additional benefits such as improved oil
passages, adjustable transbrake release, increased material thickness in critical areas,
which results in the near elimination of case breakage. It also fits under stock floorpans
making it far easier to install in your car, than an external SFI approved trans shield.
The JW Ultra-case is SFI certified. The ultracase can be used with our SFI
certified deep transmission pan to eliminate the need for any external straps or shields.

wide range of engines. You are not limited to using the powerglide only behind GM engines.
With the use of the appropriate Ultra Bell bellhousing, your powerglide automatic
transmission can be used with GM, Mopar, Ford and other engine types.
