Transmission Oil Pan Gasket 3516821020 for Toyota Lexus

To ensure accurate fitment, please provide your 17-digit VIN before placing your order. Transmission configurations can vary based on the production date, engine model, and regional market specifications. Our team will cross-reference your VIN with the manufacturer's database to verify that this gasket is the correct match for your transmission.

Common symptoms include visible transmission fluid drips under the vehicle, low fluid levels, or wetness around the perimeter of the oil pan. If you notice fluid accumulation on the underside of the transmission housing, the gasket may have hardened or cracked, requiring a replacement to prevent further leakage and potential transmission damage.

Ensure the vehicle is parked on a level surface and the transmission has cooled completely to avoid burns from hot fluid. Gather the necessary tools, including a socket set, a drain pan, and a torque wrench. Always wear protective gloves and eyewear when working with automotive fluids.

Place a drain pan under the transmission and carefully remove the oil pan bolts to drain the old fluid. Once drained, remove the pan and peel away the old gasket from the mating surfaces. Thoroughly clean the pan flange and the transmission housing surface to remove all old gasket material and debris.

Position the new genuine gasket onto the clean oil pan surface, ensuring all bolt holes are perfectly aligned. Carefully reinstall the oil pan to the transmission housing, tightening the bolts in a cross-pattern to ensure even pressure. Consult a professional technician if you are unsure about the correct tightening sequence or torque specifications.
