The above photo shows a comparison between the Deep Pan and the Stock Pan. This pan has one location cast into the pan that can be machined for use with aftermarket sensors and gauges, it can accommodate from 1/8 NPT to 1/2 NPT.
The only gasket we know about for the Allison is the reusable gasket. A flexible, thin rubber cork gasket works best with PML pans. With the thick, hard reusable gasket, make sure that it is clean and free of nicks or there will be a leak. You may need to file down the gasket bolt holes so the PML pan seals correctly. Some installations have used a very thin bead of silicon(RTV) instead of the gasket.
In the above photo you can see the drain hole, located on the front of the pan. The pan has a boss on the inside of the casting that can be machined for a temperature sensor, this is also located on the front edge. It can accommodate between 1/8 and 1/2 NPT and we can drill it to your specifications for a $45 fee.
In the above photo you can see the cast-in filter supports in the bottom of the pan. The transmission pan features filter supports that are an integral part of the floor.
