PML’s aluminum 4L80E low-profile transmission pan holds 1.5 more quarts than a factory pan and has 3/16-inch-thick wall construction with raised fins for increased cooling capacity. There is a boss cast into the pan that can be machined upon request. A magnetic drain plug keeps metal particles from floating around suspended in transmission fluid. We opted for a low-profile pan due to clearance reasons.
