Product Details and Specifications

The Dorman 265-814 transmission oil pan is designed to meet the specifications required by various GM vehicles such as the Chevrolet Impala, Buick LaCrosse, Pontiac Grand Prix, and Saturn Aura. Its steel construction ensures resistance to impact and corrosion, while the included drain plug simplifies maintenance by allowing quick fluid drainage without removing the entire pan. The pan’s 1.5 mm thickness provides structural integrity, and the one-piece gasket configuration helps maintain a reliable seal to prevent leaks. With a capacity of 13.5 quarts, it accommodates the transmission fluid volume needed for smooth operation.

Compatible Vehicles and Applications

  • Chevrolet models such as Impala, Malibu, and Monte Carlo
  • Oldsmobile models including Aurora and Intrigue
  • Pontiac models like Grand Prix, G6, and Bonneville
  • Saturn models including Aura and Vue

This transmission oil pan is suitable for vehicles requiring a steel pan with a drain plug and specific mounting hole configuration, making it a practical replacement for worn or damaged pans in these GM models.

Common Issues Addressed by This Transmission Oil Pan

  • Leaking transmission fluid due to damaged or corroded pans
  • Difficulty draining transmission fluid without a drain plug
  • Structural damage from road debris or impact
  • Improper sealing causing fluid loss and transmission performance issues
  • Replacement of worn or rusted factory pans

Installation Notes and Tips

Ensure the transmission surface is clean and free of old gasket material before installation. This pan uses a one-piece gasket configuration; however, the gasket is not included and must be sourced separately. Tighten mounting bolts evenly to the manufacturer’s torque specifications to avoid warping the pan. The included drain plug should be inspected for proper sealing and replaced if necessary during installation.
