4 A deeper transmission pan like this unit from Mag-Hytec is always an excellent idea because they act as a heat sink, hold more transmission fluid, and are much more robust than the stock pan. The Mag-Hytec pan also has a drain plug and a pre-drilled hole for a transmission temperature sender. There are two pan sizes available for the Dodge transmissions, but I opted for the four-quart-more pan instead of the six-quart one for clearance reasons under the truck. You might notice that the pan is inscribed with “727” under the Mag-Hytec logo. This same pan is used for the 518, 44RH, 46RH, 46RE, 47RE, and 48RE as well.
