Why Choose Banks Ram-Air Transmission Pan?

The Banks Ram-Air Transmission Pan outperforms competitors by combining advanced cooling technology with robust engineering. Unlike other pans with haphazard fin designs, Banks’ FlowThru Fins™ and forward-facing Ram-Air scoop maximize heat transfer, ensuring your transmission runs cooler and lasts longer. The die-cast process provides a smoother interior for better fluid flow, while the integrated anti-slosh baffles and full fluid drainage design enhance performance and ease of maintenance.
