J W Performance 32310 - J.W. Performance Powerglide Ultra-Case & Kits

SFI-Approved,
No Trans Shield Required

This one-piece aluminum casting replaces the stock GM case and allows versatility when an adapter-style Ultra-Bell housing is used. Ultra-Case has an adjustable transbrake release; CNC-machined oil passages to increase oil flow and improve performance; and more material in critical areas to reduce flex around the shift lever, which lowers the chance of the case cracking.
