Mega Monster Transmissions
Engineered to Dominate, the 4L80E 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 engines producing up to 550 horsepower using pump gasoline. 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 4l80e transmission cooler when you purchase a 4l80e 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.
