Overview
The Mag-Hytec GM Allison A1000 Deep Sump Transmission Pan is a painted aluminum transmission pan for the Allison A1000 transmission, with a total oil capacity of 10.5 quarts. Its overall height is 5 1/2 in, and the title names only the transmission, not vehicle years.
Mag-Hytec casts the body from A356-T6 aluminum and powder coats it black, with machined cooling fins to aid heat transfer. Fluid can be changed without taking the pan off. Each unit has a magnetic drain plug and 303 stainless steel hardware.

Choosing a deep sump pan
A deep sump pan adds fluid capacity and more surface area for heat to leave the transmission. That extra fluid helps keep temperatures steadier when the vehicle works hard, such as towing or running long grades. The added depth also means the pan sits lower, so clearance to the crossmember and driveline needs a check.
Before choosing a deep pan, look at the space under the transmission and the routing of any cooler lines. A pan that hangs lower can strike rocks or the exhaust on rough trails. Fluid level should be checked after install and after a short drive, since a larger sump can take more fluid.
- Check crossmember and driveline clearance
- Replace the filter when the pan comes off
- Check fluid level after a short drive
- Inspect cooler line routing before installing
