Mega Monster Transmissions
Engineered to Dominate, the E4OD Mega Monster transmission is tough enough to withstand the rigors of even the toughest trucks and off-road vehicles. It is ideal for vehicles powered by engines producing up to 450 horsepower(900tq) with a non-nitrous system using pump gasoline. The Mega Monster is recommended for any type of heavy towing or plowing use around 8,500lbs! Equipped with a Manual/Automatic valve body, most units allow you to manually shift the vehicle into each gear change or, by placing it in the drive position, remain fully automatic. In either mode, you get a racetrack shift that bangs through the gears giving you all the right to say "Eat My Shift!". When you use the manual gear selection feature, the Mega Monster upshifts and downshifts when you move the shift lever, (please note, in order to have complete control of the RPM shift timing you must upgrade to a full manual valvebody). When you select the normal drive position, the transmission retains its firm, automatic shifts for the ease of driving you look for in an automatic transmission.
The Mega Monster Transmission features: the latest technology in our industry with only the best internal components for increased strength, dependable performance and monster torque capacity. All Monster transmissions are thoroughly inspected, blue printed and tested to ensure that your investment is completely flawless. For the system to operate properly, all throttle linkage, vacuum lines and kick-down components must be connected and adjusted properly.
*Special Note: If you are planning a direct transmission swap it is recommended to re-use your existing speedometer gear for your new unit. This Monster E40D Transmission does not come equipped with a new Speedometer Gear. Please Contact Us to purchase a proper speedometer gear for your application.
*Included with your Monster E40D Transmission is a 1405 Hayden Transmission Cooler Kit.
