Mega Monster Transmissions
Engineered to Dominate, the 700R4 4x4 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 500 horsepower(450tq) with a naturally aspirated system using pump gasoline. The Mega Monster 4x4 is recommended for any type of heavy towing use around 5,500lbs GVW! 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 custom made in the USA and quality checked to ensure your peace of mind. For the system to operate properly, all throttle linkage, vacuum lines and kick-down components must be connected and adjusted properly.

If you don't already have one, we recommend getting a 700r4 transmission cooler when you purchase a 700r4 transmission.
The 700R4 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 transmission. The 700R4 is a popular transmission swap for muscle car restorations to add the overdrive option & to update to a modern transmission. Converting from a Turbo 350 or Turbo 400 3-speed to the 700R4 Monster transmission may also increase the value of your vehicle.
*Special Note: If you are planning a direct transmission swap it is recommended to re-use your existing extension-housing and speedometer gear for your new unit. This does not come equipped with a new Speedometer Gear. Certain vehicle specific extension-housings may not be available with this unit. In most cases, you will be required to swap your original extension-housing (this will NOT void your warranty). Please Contact Us to purchase a proper speedometer gear for your application or if you are unsure if your extension-housing will need to be reused.
