Overview
The Mag-Hytec 727-DD is an extra deep sump transmission pan for Dodge 727 automatic transmissions, supplied painted. It is built to hold more fluid and cool it better than a stock pan, which suits heavy-duty and towing use. Mag-Hytec describes its covers and pans as heavy duty units for hard working recreational and service vehicles.
The pan is cast from A356-T6 aluminum with machined cooling fins and a textured black powder coat. It holds 4 quarts more oil than the stock pan and has a magnetic drain plug that traps worn gear material. Confirm the pan matches your transmission before installing it.
Key features
- Extra deep sump holds 4 quarts more oil than the stock pan
- Finned aircraft aluminum construction for improved cooling
- Magnetic drain plug traps worn gear material
- Allows fluid to be changed without removing the pan
- Includes filter spacer block for overdrive transmissions
- Sealed with ARP 568 O-rings; all hardware is 303 stainless steel
Overdrive spacer and filter setup
Overdrive transmissions can have a different filter arrangement, so the spacer block affects how the filter sits in the pan. Check the spacer’s position and the filter’s seal before the pan is bolted up. A misplaced spacer can cause restricted flow or a loose fit.
Fluid volume matters in heavy use. Extra capacity gives the fluid more room to hold heat, and a clean sump with an intact filter reduces the chance of debris circulating. Replace the filter when the pan is serviced, and use a fresh gasket or O-ring set. Inspect the sealing face for scratches before tightening. Torque the pan bolts evenly in a crisscross pattern. Keep a record of fluid changes for trucks that tow or carry heavy loads.
