Key Features

• Transmission filter kit for automatic transmission service
• Premium Replacement line from ATP Parts
• Helps maintain cleaner transmission fluid during routine maintenance

How It Helps

Transmission fluid naturally collects debris from normal wear over time. Replacing the filter during service helps reduce contamination that can restrict fluid flow and affect transmission operation. ATP B-406 is used on applications such as the Chevrolet Silverado 2500 HD, GMC Sierra 3500 HD, and related LCT 1000-equipped trucks where clean fluid is important for long-term transmission performance.

This part cross-references GM OE 29542833 for the same application.

Installation Notes

Confirm the transmission configuration before ordering, including cartridge type and shallow pan applications. Match the vehicle year, make, model, and notes exactly to the fitment list, especially on 2006-2010 Silverado and Sierra HD trucks and 2006-2012 Suburban 2500 or Yukon XL 2500 applications. Replace the filter during transmission service and inspect the fluid condition and pan area for debris.

Quality Assurance

ATP Parts positions this B-406 filter kit in its Premium Replacement line for service-focused coverage on GM heavy-duty applications. The design goal is to keep transmission fluid cleaner so the valve body and other vital components are less likely to become restricted by debris.
