ATP Transmission Oil Filter P/N:B-457
Keep your transmission's lifeblood clean with the ATP Automatic Transmission Filter B-240 (also written B240). It drops in as a direct-fit replacement for a wide range of GM trucks, SUVs and vans, including the 2008-2015 Cadillac CTS, 2007-2015 Cadillac Escalade, 2006-2014 Chevrolet Corvette, 2009-2021 Chevrolet Silverado 1500, 2007-2020 GMC Yukon, and 2007-2021 GMC Sierra 1500 — see the Buyer's Guide tab for the full 62-application list.
Automatic transmission fluid must stay clean for the transmission to shift and operate properly. Over time the filter loads up with accumulated debris; installing a fresh B-240 during a fluid-and-filter service restores clean flow through the filter and is a smart part of routine maintenance.

What does this ATP filter do?
It strains debris out of the automatic transmission fluid so the fluid stays clean, helping keep the valve body and other vital components from becoming clogged.
Will the B-240 fit my vehicle?
It fits 62 GM applications, including the 2008-2015 Cadillac CTS, 2009-2021 Chevrolet Silverado 1500 and 2007-2021 GMC Sierra 1500. Check the Buyer's Guide tab to confirm your exact vehicle.
When should I replace the transmission filter?
Replace it at the interval recommended in your vehicle's service information, typically as part of a transmission fluid-and-filter service.
Why is a clean filter important?
Every transmission accumulates debris from normal wear. Keeping the fluid clean helps extend transmission life and reduce the possibility of costly, avoidable repairs.
Is this the same as part B240?
Yes. The ATP part number B-240 is also written B240 — they refer to the same filter.
