P/G High Flow Filter System

The TCI P/G High Flow Filter System (SKU TCI528505) is a transmission filter kit engineered for Powerglide-equipped vehicles seeking maximum fluid circulation and engine longevity. Designed for builders and daily drivers alike, this high-flow filter assembly reduces restriction in the transmission cooling circuit, allowing cooler fluid to reach critical bearing surfaces and extend component life. Whether you're running a stock Powerglide or a modified street machine, proper filtration protects against wear particles that accumulate during normal operation and especially during spirited driving.

At 1.45 lbs and compact dimensions (10.2 x 2.2 x 11.8 inches), the P/G High Flow Filter System combines efficient filtration media with a streamlined adapter and gasket assembly. The high-flow design maintains filtration integrity while minimizing pressure drop—critical in older gearboxes where pump output is modest and every PSI of fluid pressure matters. The included adapter ensures proper fitment to Powerglide transmission housings, while the gasket delivers reliable sealing without thread-locking compound, making service intervals straightforward for home mechanics and shop professionals.

Enthusiasts restoring vintage Chevrolets, Pontiacs, and other Powerglide-equipped classics benefit most from this kit, as original filter designs often choke modern synthetic fluids and increase operating temperatures. Street rodders and restomod builders appreciate the bolt-on compatibility and the performance margin gained by reducing transmission heat. Installation requires no special tools—simply replace the filter element, apply the gasket, and thread the adapter into your pan or remote filter housing. For optimal results, pair this system with quality transmission fluid and service every 25,000 to 30,000 miles depending on duty.
