Black Beast Diesel Transmissions
Engineered to Dominate, the A618 Black beast Diesel 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 650 horsepower(1,000tq) with a non-nitrous 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 Black Beast Diesel 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 Monster 48RE Transmission 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.

**If ordering with HD 4x4 Output Shaft (from 9310 Vacumelt Steel) please see picture below of needed modification to your Transfer cases input shaft due to billet reinforcements made to new output shaft.

Thank you again for the great service, quality transmission, and torque converter, that you installed in my 2004, 4wd 2500 Dodge diesel truck. This heavy duty equipment has exceeded expectations with smooth, but solid shifting, giving me a feeling of security, that it can handle whatever this Cummings can pull. I chose your company having taken advantage of two separate tours of your operation, during open house events. Your entire staff were very knowledgeable, professional, and pleasant to work with, giving me great satisfaction that the workmanship and materials put into my transmission would be of the highest quality. Your reputation for delivering quality, long lasting transmissions, around the world, coupled with my eye witness of your operation, made my decision a simple one.
