Technical Details and Specifications

  • Contaminant buildup causing transmission wear
  • Fluid loss during engine shutdown

  • Seal leaks due to improper gasket fit
  • Replacement for worn or damaged GMC 25010441 filters

Installation Notes and Tips

When installing the Baldwin B252 transmission oil filter, ensure the gasket surface is clean and free of debris to achieve a proper seal. Hand-tighten the filter according to manufacturer torque specifications to avoid damage to the thread. Verify compatibility with your specific Allison transmission model before installation.
