Review HUGHES PERFORMANCE Premium Transmission Overhaul Box Kit Gm Th350 fits 1969-79

The Hughes Performance HP3288 Transmission Box Kit is a high-performance upgrade for 1969 to 1979 GM TH350 automatic transmissions. This transmission box kit is designed to enhance the strength, durability, and cooling capacity of your TH350 transmission.

The Hughes Performance HP3288 Transmission Box is made from heavy-duty 6061-T6 aluminum alloy, which is both lightweight and incredibly strong.

The Hughes Performance HP3288 Transmission Box Kit also includes a high-performance oil cooler and a billet aluminum oil pan. The oil cooler is designed to be larger and more efficient than the factory cooler, providing better cooling capacity and improved oil temperature stability. The billet aluminum oil pan is designed to provide better oil capacity and improved oil flow, ensuring that your transmission stays cool and lubricated under heavy load.

The HP3288 Transmission Box Kit is also designed to be easy to install. It includes all necessary hardware, including new transmission mounts, and is designed to bolt up directly to the factory transmission bellhousing. The kit also includes detailed installation instructions to help ensure a smooth installation process.

In summary, the Hughes Performance HP3288 Transmission Box Kit is a high-performance upgrade for 1969 to 1979 GM TH350 automatic transmissions.
