Moroso Transmission Pan Gasket for GM Turbo TH-350 — 3/16" Rubber-to-Steel, Leak-Resistant

Moroso 93102 is a full 3/16" rubber-to-steel transmission pan gasket engineered to replace factory seals on GM Turbo TH-350 transmissions for fast, leak-resistant installation.

This transmission pan gasket combines a 40 durometer rubber sealing surface vulcanized to a rigid steel frame to provide long-lasting resistance to deformation and fluid seepage. Designed for vehicle-specific fitment, the Moroso 93102 eliminates the need for sealant and speeds up both removal and reinstallation of the pan while resisting the compression set and breakdown common to cork and composite gaskets.

How does this gasket improve fit and seal compared with stock gaskets?

The Moroso 93102 uses a molded rubber sealing lip bonded to a steel backing so it retains shape under clamping load and heat. That construction creates a consistent, full-face contact with the transmission pan flange to reduce micro-leaks that develop over time.

• 40 durometer rubber resists permanent deformation.
• Vulcanized bond to steel frame prevents separation under stress.
• No need for additional sealant—provides a consistent factory-like seal.

Will installing this gasket save me time during service?

Yes. Because the gasket is pre-formed and requires no sealant, it simplifies both removal and reinstallation. Technicians and DIYers will find bolt alignment easier and cleanup reduced when compared with messy gasket compounds or multi-piece materials.

• Pre-formed shape speeds alignment of pan and bolts.
• No curing time—reassembly proceeds immediately after installation.
• Cleaner process with less solvent and surface prep required.

How durable is the Moroso 93102 under real-world conditions?

The design resists the common failure modes of traditional cork or composite gaskets: compression set, tearing, and oil absorption. The combination of 3/16" thickness and a steel frame gives structural support that maintains consistent clamping pressure across flange surfaces.

• Full 3/16" thickness for reliable compression resistance.
• Rubber/steel combo outlasts cork composites in repeated service cycles.
• Engineered to handle heat and fluid exposure typical of transmissions.

Is this gasket compatible with my vehicle and transmission?

The Moroso 93102 is specifically shaped for GM Turbo TH-350 transmissions and is intended for vehicle-specific fitment. Always verify part compatibility with your vehicle year and transmission model before purchase to ensure fit and bolt-hole alignment.

• Designed for Turbo TH-350 transmission pans.
• Vehicle-specific fit—check year/model/transmission match.
• Direct replacement for pans requiring a 3/16" thickness gasket.

Who is this for: The Moroso 93102 gasket is aimed at professional mechanics, restorers, and committed DIY enthusiasts who want a dependable, maintenance-friendly sealing solution for GM Turbo TH-350 transmissions. If you seek a cleaner install, longer-lasting sealing performance than cork or basic composites, and a gasket that holds up to routine service intervals, this Moroso gasket is a practical upgrade for transmissions where correct fitment matches your vehicle.
