The Moroso Deep Transmission Pan is a finned aluminum replacement for GM TH350, TH400, and 700R4 automatic transmissions in Chevy muscle cars, drag cars, and street rods. When pushing your car hard at the track or in traffic, heat is the enemy—Moroso's deep pan increases capacity and drops temperatures significantly.

Cast from premium A356-T6 aluminum with a wrinkle-finish black powdercoat, this pan adds approximately 2.5 quarts of fluid capacity over factory. The deep sump design with external cooling fins reduces fluid temperature by 20–30°F under sustained use. A 1/8-inch NPT threaded port allows installation of a temperature sensor. Includes a magnetic drain plug and reusable neoprene gasket.

The additional fluid mass absorbs and sheds heat more effectively. For a TH400 behind a big-block seeing autocross or drag strip duty, this extra thermal capacity can mean the difference between a transmission that lives and one that burns up on a hot day. The deep sump also prevents pickup starvation under hard acceleration with a transbrake.

Your transmission runs hot. Fix it with the Moroso deep pan—more fluid, cooler temps, longer trans life. Order today.

Frequently Asked Questions

How much extra fluid does this Moroso deep transmission pan hold compared to stock?

This Moroso transmission pan increases fluid capacity by approximately 1 to 2 quarts over the factory pan, depending on the specific vehicle application. This extra capacity helps keep the automatic transmission fluid cooler by allowing more oil to circulate and shed heat through the pan's cooling fins. The pan is constructed from durable aluminum with reinforced ribs and a durable finish for protection and styling.

What transmissions does this Moroso deep pan fit for my vehicle?

This Moroso transmission pan is designed to fit a range of popular automatic transmissions including GM TH350, TH400, 700R4, 4L60E, and Ford C4, C6 and AOD models. It is a direct bolt-on replacement that uses the factory gasket and bolt pattern, though some applications need a different filter or pickup tube due to the deeper profile. Always confirm your transmission model and pan rail shape before purchasing.

Does the Moroso pan help lower transmission temperatures during towing?

Yes, this Moroso deep transmission pan is engineered to reduce fluid temperatures during heavy towing and stop-and-go driving by increasing both fluid capacity and heat-shedding surface area. The cooling fins transfer heat from the hot transmission fluid to the ambient air, lowering operating temperatures by 10 to 20 degrees Fahrenheit compared to a stock pan. This temperature reduction extends the life of seals, clutches, and the valve body in high-stress conditions.

What material and finish does the Moroso transmission pan use?

This Moroso transmission pan is made from cast aluminum with reinforced ribs for maximum structural strength, preventing warpage even under extreme heat cycles. The finish is a durable coating that resists chipping and corrosion, with machined details for a performance look. The combination of aluminum construction and protective finish makes this pan suitable for daily-driven trucks and performance vehicles that also see occasional towing or off-road duty. The deeper design provides increased fluid capacity for better overall cooling performance.

Can I install this Moroso transmission pan without modifying my transmission?

In most cases, the Moroso transmission pan bolts directly to the transmission case using the factory bolt pattern and a reuseable or replacement gasket, requiring no drilling or modifications. However, because this is a deeper pan than stock, you may need a longer filter pickup tube or an extension to ensure the filter sits at the correct depth in the fluid. Check the included instructions before installation to confirm all needed components.

Will this transmission pan work with aftermarket transmission coolers on my truck?

Yes, this Moroso deep transmission pan works alongside an auxiliary transmission cooler to provide maximum thermal management for your vehicle. The increased fluid capacity gives the system more thermal mass, so the combination of a deeper pan and an external cooler can reduce peak fluid temperatures by 20 to 30 degrees during extended towing. Ensure your cooler lines and fittings are compatible with the pan's ports.
