The Mag-Hytec 4R70W-D Transmission Pan is a heavy-duty upgrade designed to enhance the performance and durability of your 4R70W transmission. Crafted from high-quality A356-T6 cast aluminum, this transmission pan offers increased fluid capacity to improve cooling and extend transmission life. It features a textured black powder-coated finish with machined cooling fins that help dissipate heat more efficiently. The pan includes a magnetic drain plug to capture metal particles and keep your transmission fluid cleaner for longer. With a precision O-ring seal and stainless steel hardware, installation is straightforward and leak-free without the need for extra sealants. Ideal for trucks and vehicles that require enhanced transmission cooling and protection under demanding conditions.
The stock 4R70W pan limits fluid capacity and cooling, which shortens fluid life when the transmission works hard. This Mag-Hytec deep pan upgrades both durability and cooling. What you get:
A356-T6 cast-aluminum construction for strength and heat transfer
Increased fluid capacity for cooler, longer-lasting fluid
Machined cooling fins that dissipate heat efficiently
A magnetic drain plug to capture metal particles
A precision O-ring seal and stainless hardware for a leak-free, sealant-free install
The added capacity and finned aluminum body help keep fluid temperatures down under demanding conditions, while the O-ring seal makes service clean and reliable without extra sealant. It is an easy upgrade for trucks that need better transmission protection.
Frequently Asked Questions
