Keep your automatic transmission's fluid clean and flowing with the ATP Automatic Transmission Filter Kit (MPN B-393, also written B393). It drops in as a direct-fit replacement for a large list of GM applications, including the 2005-2009 Buick Allure, 1994-2005 Buick Century, 1992-2005 Buick LeSabre, 2000-2011 Chevrolet Impala, 1991-2001 Chevrolet Lumina, 1995-2007 Chevrolet Monte Carlo, and 1991-2008 Pontiac Grand Prix — across engines such as L4-2.2L, V6-3.1L, V6-3.4L, V6-3.8L, and V8-5.3L. See the "Vehicles it fits" section for the full list of 109 applications.
- Exact-fit design: ATP transmission components are built as no-compromise replacement parts for the listed applications.
- Filtration job: The filter strains debris and contaminants from the automatic transmission fluid as it is drawn into the pump.
- Service-friendly: Intended to be installed during a filter-and-fluid service to help maintain proper fluid flow.
- Country of origin: Taiwan.
A clogged or restricted filter can starve the transmission of fluid and contribute to shifting problems, so replacing the filter during routine transmission service helps keep the fluid clean. If a restricted filter is the cause of your transmission's fluid-flow issue, this kit replaces it.
