How does the included drain plug and gasket improve serviceability?

• Drain plug for controlled fluid removal
• Pre-cut gasket sized for a correct seal
• Mounting bolts included to streamline installation

What materials and durability can I expect from this replacement pan?

Riyhch manufactures the pan from a sturdy stamped metal designed to resist everyday road impacts and offer long-term stability. The surface resists common wear so the pan holds shape and bolt alignment over repeated service cycles.

• Durable finish to help resist corrosion in operating conditions
• Designed to maintain sealing and bolt alignment over time

How difficult is installation and do I need special tools?

Installation is straightforward for experienced mechanics: remove the old pan, clean the transmission flange, position the new gasket and pan, and torque the included bolts to specification. Riyhch does not include installation instructions, so professional installation or reference to a service manual is recommended if you are unsure.

• Basic hand tools and torque wrench required
