Powerstroke Transmission Pan

The 6R140 pan fits 2011-2019 Ford 6.7L Powerstroke F250/F350/F450 (automatic). The 5R110 pan covers 2003-2010 Ford F250/F350/F450 with the 6.0L and 6.4L Powerstroke. Always verify your exact transmission model—not just engine year—since some model years overlap between transmission generations.

Aftermarket aluminum pans add fluid capacity (2–4 more quarts), improve heat dissipation through cooling fins, and reduce pan flex under hard cornering and towing loads. On heat-sensitive 6.0L and 6.4L Powerstroke platforms, these benefits mean lower fluid temperatures, extended fluid life, and improved clutch durability during sustained high-torque operation.

Not automatically. Under the Magnusson-Moss Act, the manufacturer must prove the aftermarket part specifically caused any covered failure. Keep your stock pan as a fallback, use the correct ATF spec (Mercon V for 6.0L, Mercon LV for 6.7L), and document the installation. If transmission issues arise, reverting to the stock pan helps demonstrate the aftermarket part wasn't at fault.

Yes, but the improvement varies. A deep aluminum pan alone drops fluid temperatures by 10–20°F through increased thermal mass and better heat dissipation. For maximum cooling during towing or in hot climates, pair the pan with an auxiliary external transmission cooler—a combination that can reduce fluid temperatures by 30–60°F versus stock.

Beginner-to-intermediate DIY. Drain the existing fluid, remove the old pan and clean the gasket surface, install the new pan with fresh sealant, and refill with the correct fluid. Most owners finish in 1–2 hours. SPELAB pans include drain plugs for easier future fluid changes—a key advantage over the stock non-drain design.
