TH180 TH180C Transmission Filter Kit for GM Chevy Geo Suzuki 1969-1998

Keep your TH180/TH180C automatic transmission shifting the way it should with this complete filter kit, built for GM, Chevrolet, Geo, and Suzuki vehicles from 1969 and up. This kit brings together everything needed for a proper transmission service in a single package: a replacement transmission filter, filter gasket, and nitrile pan gasket.

Over time, the original filter and pan gasket can become worn, brittle, or restricted, leading to symptoms such as harsh or delayed shifting, fluid leaks around the pan, and reduced fluid flow to internal components. Installing this filter kit during routine maintenance or a fluid service helps restore proper circulation and supports a tighter seal at the pan, addressing many of the most common transmission service needs.

This kit is compatible with vehicles using the TH180/TH180C (3L30) automatic transmission, including applications such as the Chevrolet Chevette, GEO Tracker, and Suzuki Sidekick 1989-1998. Always verify your transmission model and vehicle year before ordering to confirm proper fitment.

For best results, pair this filter kit with Lubegard automatic transmission fluid protectant during your service for smoother shifts and added long-term protection.

Kit Includes: • 1 Transmission Filter (1969-Up) • 1 Filter Gasket (1969-Up) • 1 Nitrile Pan Gasket
