Revised Key Features:

1. Mopar Engineering Revision: Our case is a meticulous revision of Mopar Engineering, addressing weaknesses and incorporating extensive improvements for superior performance in racing applications.
2. Rigid Aluminum Casting: The case boasts an extra-rigid, heavy-duty aluminum casting that eliminates the need for external protective shields. This precision design goes beyond standard expectations, substantially decreasing the risk of case fatigue and failure. Notably, the overdrive extension housing mounting flanges incorporate increased material, boosting harmonic tolerance by 40%. This strategic enhancement makes the case remarkably less susceptible to hairline cracks caused by driveline vibrations, ensuring unparalleled durability and performance.
3. Versatile Front Flange: The CNC machined front flange accepts OE front pump assemblies, and a bolt-on bellhousing, with Ford and GM adapting bellhousings coming to market soon, which will allow a seamless install when choosing a 47re/48re transmission in your GM or Ford racing application.
4. Additional Ports for Precision: Extra 1/8 pipe ports have been added for more precise pressure readings. The case maintains the ability to use a governor and speedometer if required.
5. Bolt-In Sprag Design: The case features an upgraded Bolt-In Sprag design, securing the sprag race for enhanced reliability.
6. Advanced Datalogging: Additional pressure ports enable more advanced datalogging, including Converter Lock and Unlock, and 2nd gear apply ports.
7. Reinforced 2nd Gear Band Anchor: The 2nd gear band anchor area is reinforced to prevent cracking under high 2nd gear apply pressure, ensuring durability in demanding conditions.
