Mega Monster Transmissions
Engineered to Dominate, the 4L65E 4WD Mega Monster transmission is tough enough to withstand the rigors of even the toughest heavy duty trucks, used for towing/hauling or off-roading. It is ideal for vehicles powered by 4.8, 5.3, LS1, or 6.0L engines producing up to 500 horsepower with a non-nitrous system using pump gasoline. Equipped with a Reprogrammed Automatic valve body, most units allow you to shift the vehicle into each gear change or, by placing it in the drive position, remain fully automatic. In either mode, you get a heavy duty shift that bangs through the gears giving you all the right to say "Eat My Shift!".
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, ECM computer code(s) must be cleared prior to initial drive of new transmission. We recommend using a Snapon-OTC or Dealer scanner for this procedure.
