• Seal composition retains elasticity despite repeated thermal shock cycles
• Internal cores manage pump-induced pulsation without losing structural form
• Filter-to-sump alignment minimizes restriction during rapid fluid circulation

Allison Transmission Filter Kit 

The Allison Transmission Filter Kit provides a matched twin-filter arrangement tailored for the 3000 and 4000 series transmissions. The filters promote steady fluid cleanliness by capturing wear particles and clutch-material debris before they affect shift quality or hydraulic pressure balance. Each filter is validated to withstand harsh environments, including thermal cycling, heavy towing schedules, and urban stop-and-go operation. The kit’s two-filter configuration aligns with OEM expectations for sump depth, making sure the correct flow and pressure characteristics during cold starts and extended service intervals. Many service centers rely on the Allison 29558329 because it eliminates inconsistencies caused by mismatched aftermarket filtration.
