Banks Billet™ Torque Converter-E40D

PICKUP/EXCURSION with E4OD/4R100 automatic; limited year range availability:
With its multi-disc lockup clutch assembly and improved forged-steel billet housing that maintain solid contact without flexing, the new Banks Billet Torque Converter with RaceLock® technology provides far greater torque capacity than stock (1100 lb-ft vs. 740 lb-ft). And because the lockup clutch is slip-resistant, transmission fluid temperatures stay cooler and transmission life is prolonged. From its single-piece billet housing CNC-machined from forged steel to the furnace-brazed turbine and impeller, and from the furnace-brazed and hardened turbine hub to the hardened pump drive made of 4130 chrome-moly steel to withstand massive torque, the Banks Billet Torque Converter is built for precision, performance and long-lasting durability. It's meticulously designed to properly match the Ford's torque band to deliver the maximum power to the wheels and improve acceleration. The Banks Billet Torque Converter is also a smart upgrade for trucks modified for increased performance. The entire assembly is balanced and blueprinted for ultimate performance and smoothness.

For optimal automatic transmission performance, Banks recommends its TransCommand® to manage line pressure, provide sure and sturdy shifts, lower transmission fluid temperature and further improve transmission durability. For power upgrades to Fords with E40D or 4R100 transmissions, TransCommand is required.
