93102 Transmission Oil Pan Gasket for GM Turbo 350 — Direct

The lodfGL 93102 is a direct-fit replacement transmission oil pan gasket for GM Turbo 350 applications, built from 72 durometer oil-resistant rubber bonded to a 0.5 mm galvanized steel shim for a durable, leak-resistant seal.

This gasket is engineered to match the bolt pattern and dimensions of the Moroso 93102 and GM Turbo 350 pans while improving dimensional stability and sealing performance over cork or basic rubber gaskets. The bonded steel shim minimizes distortion and compression set, and the double-vulcanized finish creates a consistent sealing face that installs easily without additional sealant on clean, flat mating surfaces.

How does this gasket improve sealing compared with cork or simple rubber versions?

The combination of a 0.5 mm galvanized steel shim and 72 durometer oil-resistant rubber reduces warping and uneven compression that commonly cause leaks. Double-vulcanization produces a uniform surface that conforms to the pan and transmission flange for a steady seal under vibration and heat cycles.

• Bonded steel shim prevents shape changes and maintains bolt-hole alignment.
• 72 durometer rubber resists oil swelling and compression set.
• Double-vulcanized finish yields a consistent, leak-resistant sealing face.

Will this fit my GM Turbo 350 pan and replace a Moroso 93102 gasket?

Yes — the lodfGL 93102 is manufactured to match the bolt pattern and overall profile of GM Turbo 350 pans and is a direct replacement for the Moroso 93102. It aligns with existing bolt holes and sealing surfaces so replacement is straightforward.

• Direct bolt-hole compatibility with GM Turbo 350 pans.
• Designed as a one-to-one Moroso 93102 substitute.
• No trimming required when used on matching pans and flanges.

How simple is installation and do I need gasket maker or sealant?

Installation is straightforward: the gasket is rigid enough to hold shape for bolt-hole alignment and thick enough to accommodate slight surface irregularities. On clean, flat mating surfaces the gasket forms a reliable seal without additional sealants; use sealant only if surfaces are damaged or very uneven.

• 3/16" total thickness for durability and ease of alignment.
• No sealant required on clean, flat surfaces (recommended practice).
• Reusable when removed carefully and flange remains undamaged.

What durability advantages does the 72 durometer rubber and steel shim offer?

The medium-hardness rubber resists compression set and oil degradation, while the thin galvanized steel shim provides structural stiffness to limit permanent deformation. Together they extend service life compared with softer materials and keep sealing integrity under repeated heat and vibration cycles.

• 72 durometer rubber minimizes permanent compression over time.
• Galvanized steel shim (0.5 mm) boosts dimensional stability.
• Double-vulcanized construction resists cracking and delamination.

Who this is for: The lodfGL 93102 gasket is intended for mechanics, restorers, and DIY enthusiasts working on GM Turbo 350 transmissions who want a dependable, drop-in Moroso 93102 replacement that lasts longer than cork or basic rubber gaskets. It suits performance and daily-drive applications where improved dimensional stability, reusable construction, and a leak-resistant seal are priorities.
