Dorman 265-580 transmission oil pan for the 2019-2021 Chevrolet Silverado 1500 and other vehicles adds a drain plug to the pan. On certain General Motors cars and trucks the original pan has to be lowered carefully to avoid spilling fluid, and this Dorman OE FIX design avoids that.
- Drain plug for draining the fluid without lowering the pan
- New magnet, so the original magnet is not reused
- Replaceable oil filter, level check plug and gasket included
- One-piece steel pan with a 10 mm drain thread diameter
Quick facts
- Part: Dorman 265-580 transmission oil pan
- Fits: 2019-2021 Chevrolet Silverado 1500 and other vehicles
- Material: Steel
- Condition: New
A transmission fluid leak at the pan seam or a dented, rusted pan can mean the pan needs replacing. A leak alone does not prove the pan is at fault, since a leaking cooler line can drip fluid in the same area.
