Mega Monster Transmissions
Engineered to Dominate, the 4L65E 2WD Mega Monster transmission is tough enough to withstand the rigors of even the toughest street machines delivering tire-spinning shifts race after race. It is ideal for vehicles powered by 4.8, 5.3, LS1, or 6.0L engines producing up to 500 horsepower with a naturally aspirated 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 racetrack 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 quality checked 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 the replacement transmission. We recommend using a Snapon-OTC or Dealer scanner for this procedure.

The 4L65E has a 3.06 ratio in first gear, which is 20% lower than most transmissions. The 30% overdrive will give a 30 to 40% increase in gas mileage on the road when compared to a 3-speed automatic transmission.
*Special Note: If you are planning a direct transmission swap it is recommended to re-use your existing tail-housing and VSS (Vehicle Speed Sensor) for your new unit. This does not come equipped with a new VSS (Vehicle Speed Sensor). Certain vehicle specific tail-housings may not be available with this unit. In most cases, you will be required to swap your original tail-housing (this will NOT void your warranty). Please Contact Us to purchase a proper VSS (Vehicle Speed Sensor) for your application or if you are unsure if your tail-housing will need to be reused.
