RTS Transmission Pan Gasket, GM TH350, Red Silicone Bead W/Steel Core, Lubelocker Style, 1.25mm Thick, Each

Reusable silicone-beaded pan gasket that ends transmission leaks for good.

• ▸Steel-core construction resists crush and distortion under load

• ▸1.25mm thickness suits standard GM TH350 pan rails
• ▸Handles wide temperature swings without weeping or hardening
• ▸Reusable across multiple pan removals, unlike paper alternatives

“Where the build starts. Everything downstream answers to it.”

Paper gaskets compress unevenly and RTV leaves residue that contaminates fluid — neither belongs near a transmission you depend on. The steel core keeps this gasket flat and true, while the moulded silicone bead does the actual sealing work without sealant compounds. At $52.92 it pays for itself the first time you pull the pan and reinstall it without sourcing a replacement.
