Aluminum Trans Pan GM 4L80E 3 Qt.

The B and M Aluminum Transmission Pan for GM 4L80E with 3-quart capacity is a finned deep-sump upgrade designed for builders and enthusiasts seeking improved cooling and fluid retention in high-performance transmission applications. This natural aluminum pan adds critical fluid volume while the finned design increases surface area for better thermal management—essential when pushing the 4L80E beyond stock operating parameters or in demanding towing and performance scenarios.

The 3-quart capacity increase provides a larger fluid reservoir, which translates to more consistent transmission temperatures during extended use and reduced risk of fluid starvation under aggressive acceleration or heavy load conditions. The finned aluminum construction delivers superior heat dissipation compared to stock stamped-steel pans, while maintaining the durability required for street and strip applications. Dimensions of 15.9 x 5.45 x 23 inches accommodate most engine bay layouts, and the 12.27-pound weight reflects the aluminum construction without sacrificing structural integrity. This pan is engineered specifically for the 4L80E transmission platform, ensuring proper fitment and fluid management for this robust four-speed automatic.

This upgrade appeals to hot rod builders, truck owners executing transmission builds, and performance enthusiasts who recognize that transmission cooling and fluid capacity directly impact reliability under load. Whether supporting a modified engine combo, frequent towing, or track-oriented driving, the increased pan capacity and improved thermal design reduce operating temperature and extend transmission service life. B and M Automotive has long focused on transmission cooling and fluid management products, making this pan a straightforward bolt-on improvement for anyone serious about 4L80E longevity and consistency.
