Installed on a 1997 GMC K2500 with a 4L80-E transmission to replace a rotten 21 year old oil pan. Fit and quality from the factory. I recommend using a reusable factory gasket, ACDELCO 8677743. A nice feature compared to the original pan is the drain plug. The factory sump uses a torx head, while this sump uses a regular hex head screw to prevent the rounding that occurs with torx fittings.
