10L1000 service kit with Banks deep pan

L1000 Transmission Service Kit with Banks Ram-Air Deep Pan (2020–2026 GM 2500HD / 3500HD Duramax)

Upgrade your transmission service with this premium 10L1000 complete service kit, designed for 2020–2026 Chevrolet Silverado HD and GMC Sierra HD 2500/3500 trucks equipped with the 10L1000 Allison transmission. This kit combines essential service components with the high-performance Banks Ram-Air Deep Transmission Pan to dramatically improve cooling, fluid capacity, and transmission protection.

The Banks Ram-Air Deep Pan is engineered with a patented forward-facing scoop that forces airflow directly across the pan’s cooling fins as the vehicle moves, actively pulling heat out of the transmission fluid. Unlike standard pans that rely only on passive cooling, the Ram-Air design increases airflow under the truck for superior heat dissipation under towing, hauling, and heavy-load conditions. The deep-pan design also adds approximately 3 extra quarts of transmission fluid capacity, helping stabilize temperatures and extend transmission life.

This complete kit includes ACDelco DEXRON ULV transmission fluid, a new internal filter, and gasket, making it the perfect solution for a full transmission service while upgrading to the high-performance Banks Ram-Air pan.
