Some models of Sierra and Silverado can use this pan but may require modification of the heat shield. Please check carefully for clearance for a deeper pan.

Earlier model vehicles will need a pan without a slant to avoid interference with transmission internals. See this extra capacity PML pan for GM 4L80E/4L85E transmissions on early model trucks.

The pan has a boss that can be machined for a temperature sensor.
