Due to a requirement of very specific measurements of the tail shaft, your core is required to build this unit. If you are unable to provide us with your core, we do have other options available. Please give us a call at 1-800-708-0087 and we will be more than happy to help get you back on the road!

Mega Monster Transmissions
Engineered to Dominate, the Big Block C6 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. 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.


*Special Note: If you are planning a direct transmission swap it is recommended to re-use your existing extension-housing and speedometer gear. 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.
