More transmission fluid can make a real difference when a truck is working hard. This deep 10L80 transmission pan adds extra fluid capacity while also giving the transmission more aluminum surface area to help manage heat.
Designed for compatible 2020–2023 GM vehicles with the 3.0L Duramax and 10L80 transmission, this heavy-duty aluminum pan holds approximately 4 additional quarts of transmission fluid compared with the standard pan.
The added capacity gives the fluid more time to absorb and shed heat, which can help maintain more stable transmission temperatures during towing, hauling, or extended driving.
More Fluid Capacity
The deeper design increases transmission fluid capacity by approximately 4 quarts.
That additional volume can be useful when a transmission is subjected to higher operating temperatures. More fluid takes longer to heat up and provides additional volume for the transmission\'s lubrication and cooling system.
For trucks that regularly tow, haul, or spend extended periods under load, maintaining more stable transmission temperatures can be especially useful.
Built for Heat Management
The pan isn\'t simply deeper.
External cooling fins increase the available surface area so airflow can carry heat away from the transmission fluid. Inside the pan, integrated heat sinks also help transfer heat while the internal structure works as a baffle to limit excessive fluid movement.
This combination gives the pan a more functional role in transmission temperature management rather than simply adding capacity.
Heavy-Duty Aluminum Construction
The cast aluminum construction provides a substantial upgrade over a basic stamped transmission pan. Cast gussets add additional structural support, making the pan better suited to demanding truck applications.
The raw aluminum finish also gives this version a straightforward appearance without an added coating or painted finish.
Magnetic Drain Plug
The billet stainless steel drain plug uses a high-power neodymium magnet to collect ferrous metal particles suspended in the transmission fluid.
Catching those particles at the pan helps keep them from continuing to circulate through the transmission.
