atp automotive FG-300 Automatic Transmission Oil Pan Gasket — Reusable OE-Style, Sandwich Construction

ATP FG-300 is a reusable, OE-style automatic transmission oil pan gasket designed to deliver an exact-fit seal for compatible transmissions without the need for sealant.

When you need a reliable replacement gasket that matches original equipment fit and function, the ATP FG-300 offers sandwich-style construction that lets technicians reinstall the gasket after inspection or service. Built to the same dimensions as factory parts, this gasket simplifies pan removal and reinstallation while reducing the risk of leaks when installed correctly. It’s lightweight, compact to ship, and packaged as a single unit for easy inventory handling.

How does the FG-300 match OE fit and performance?

The FG-300 is manufactured to reproduce original equipment dimensions and mounting hole alignment so it seats correctly against the transmission pan and case. Its profile controls compression under bolt torque and minimizes uneven crush or extrusion that can create seep points.

• Precise hole pattern for factory bolt locations
• Consistent thickness for predictable sealing under torque
• Sandwich-style construction for controlled compression

Can this gasket be reused after removing the transmission pan?

Yes. The gasket’s sandwich-style construction is specifically designed to allow reuse after a service interval or inspection, provided it remains undamaged and the sealing surfaces are clean. Reuse can save time and reduce waste compared with single-use materials.

• Reinstallable when undamaged and free of debris
• Check for nicks, tears, or permanent deformation before reuse
• Clean mating surfaces to maintain reliable sealing

What are the physical specs and package details I should know?

The ATP FG-300 ships as a single gasket packaged to minimize bending or distortion. It has compact shipping dimensions and low package weight, making it convenient for parts counters or online orders.

• Package dimensions: 19.99 L x 15.24 W x 0.99 H inches
• Weight: approximately 0.70 pounds per package
• Sold individually—package quantity: 1 gasket

How should I install and maintain the FG-300 for best results?

Install the gasket on a clean, dry pan and torque bolts to the vehicle manufacturer’s specifications in the recommended sequence. Avoid over-tightening, which can crush the gasket and impair its reseal capability; after service, inspect the gasket for any signs of damage before reusing.

• Clean mating surfaces thoroughly before installation
• Tighten bolts in manufacturer-recommended pattern and torque
• Replace if torn, compressed beyond recovery, or contaminated

Who is this for: The ATP FG-300 is aimed at professional mechanics, independent repair shops, fleet maintenance teams, and DIY enthusiasts who require a reliable, OE-style gasket that can be reused when appropriate. It’s especially useful where correct alignment and predictable compression are critical for leak-free transmission pan seals, and for anyone looking to maintain parts continuity with original equipment fitment while keeping inventory simple.
