Banks adds their Ram-Air cooling to the heavy-duty Allison 10L1000 transmission for 2020-2025, using technology from their patented differential covers. The Banks Ram-Air Transmission Pan keeps fluid oil fresh by expelling more heat than stock and other brands. It also provides three extra quarts of space, a break-away Ram-Air scoop, and Banks FlowThru Fins for maximum cooling. With cooler fluid, your transmission will last longer.
