Black Beast Diesel 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 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 thoroughly inspected, blue printed and quality checked to ensure that your investment is completely flawless. For the system to operate properly, all throttle linkage, vacuum lines and kick-down components must be connected and adjusted properly.

I'm really ecstatic about this transmission Monster Transmission has sent me I left Texas and my transmission wasn’t up to par all the way to California, like 9-10 miles a gallon on this diesel and the transmission just not really knowing if it is going to make it or not. Got to California, got hooked up with Monster Transmission, each and every representative that I have dealt with especially Corey, went out of their way to help me out, got the transmission delivered to California, got it in by myself you know but actually it was Sunlight Mechanic, got it all done, got it in I am ecstatic about it I wish I had done it years ago, even if the fact of the matter if I had done the transmission or not had a failure in my transmission I probably would have ordered a Monster Transmission to replace it with but it was all good, I can't beat the transmission I am really excited about this thing, I've got my shift back in here but my Monster Transmission did me a great job, great transmission, love the shift on it, love the torque, love everything about it couldn’t ask for a better deal and that is about it but I recommend Monster Transmission to everyone that needs a replacement.
