Glide Gasket & Seal Kit

The COAN Glide Gasket & Seal Kit (COA-12121) is a complete overhaul gasket and seal package engineered for Powerglide automatic transmissions. This composite gasket kit contains all necessary sealing components required to rebuild or service a Powerglide unit, making it an essential part for any transmission overhaul or repair. The kit streamlines the rebuilding process by consolidating all gaskets and seals into a single, organized package.

Powerglide transmissions are known for their robust construction and simplicity, which makes them popular for street performance builds, marine applications, and vintage hot rod restorations. When rebuilding or resealing a Powerglide, precision gaskets and seals are critical—inadequate sealing leads to fluid leakage, loss of hydraulic pressure, and transmission slippage. This COAN kit uses composite gasket materials proven to maintain seal integrity under both street and moderate racing pressures, fitting the Powerglide's broad operating range. The complete gasket set covers all major sealing surfaces, reducing the risk of missed seals during assembly.

Rebuilders and transmission shops choose this kit for routine overhauls, fluid seal replacements, and performance upgrades where stock sealing is insufficient. Whether you're restoring a classic cruiser, preparing a drag racing platform, or servicing a marine or industrial Powerglide installation, having the correct gasket and seal kit on hand prevents assembly delays and ensures leak-free operation. The compact, lightweight packaging (0.34 lbs) makes storage and transport straightforward.

The Powerglide remains one of the most adaptable two-speed automatics ever produced, with a loyal following among hot rodders, marine builders, and vintage car enthusiasts. A quality gasket and seal kit is non-negotiable for any serious rebuild, and the COAN brand has established a solid reputation in the transmission parts aftermarket for producing reliable overhaul kits that meet original equipment standards.
