Mega Monster Transmissions
Engineered to Dominate, the A518 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 600 horsepower(650tq) with a naturally aspirated system using pump gasoline. The Mega Monster is recommended for any type of heavy towing or plowing use around 26,500lbs 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.

*Special Note: If you are planning a direct transmission swap it is recommended to re-use your existing extension-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 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 VSS (Vehicle Speed Sensor) for your application or if you are unsure if your extension-housing will need to be reused.


I just wanted to thank everyone at Monster Transmissions. They were really, really helpful with my project. I did a 1997 Jeep wrangler with a 518 behind it and it's been good to work with you. Charlotte Carter has been really nice. Everyone that I dealt with at Monster has been really, really helpful. They made sure I got what I wanted when I wanted it and I just wanted to say I appreciate it. Keep up the good work. Thank you.

These transmissions are insane!!
These transmissions are insane!! Have one on my 08 Cummins and I have a banks 6 pack stacked with a diablo tuner and twin 45mm turbos I went threw two rebuilds and the original because it was blowing torque converters our blowing valves!!! I have had a monster transmission for two years and even with two full size Chevy mud trucks on a 32 foot dove tail goose neck the truck will break the tires lose loaded and the transmission just laughs at it!!! You guys rock when I buy my new truck it won't even leave the dealership until a monster transmission is installed!!! Thanks guys!!!
