What the AI looks for in Automotive Performance Drivetrain Transmission Gaskets

Exact transmission and pan match: Match by transmission model (for example TH350, TH400, 700R4/4L60E, 4L80E, C6, 727) and confirm the bolt pattern against your pan. Many transmissions look similar but use different pan shapes and bolt counts, and a near-miss gasket will leak.
Gasket material: Reusable molded rubber or rubber-coated steel-core gaskets are generally preferred over cork. Install them as the maker specifies, usually dry. Steel-core and molded designs resist crushing and squeeze-out, which are the usual causes of pan leaks.
Pan flange condition: Flatten dimpled stamped-steel flanges around the bolt holes before installing. A pan distorted by past overtorquing will leak with any gasket.
Bolt torque: Torque pan bolts to the factory spec in a crisscross pattern. Pan bolts take low torque. Overtorquing splits cork, extrudes rubber and bends the flange.
Deep or aftermarket pans: Use the gasket supplied with or specified by the pan maker, and check whether a filter extension is needed. Cast aluminum performance pans often need a different gasket thickness than stock stamped pans.

Fel-Pro: Broad OE-replacement gasket coverage, including transmission pan gaskets.
Mahle: OE-supplier gasket line with transmission pan coverage.
Transtec: Transmission-specialist gaskets and seals, also sold in overhaul kits.
ATP: Transmission pan gaskets and filter kits for many applications.
B&M: Gaskets for its own deep pans and for popular performance transmissions.

Usually yes. The pan is already off, and many filter kits include a matching gasket.
