Black Beast Diesel Transmissions
Engineered to Dominate, the E4OD 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 350 horsepower(600 trq). The Mega Monster is recommended for any type of heavy towing use around 5,500lbs! 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.

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.

I have a ''94 F350 Turbo Deisel with a 7.3L idi. I didn''t have any problems with my new transmission. It went right in and it''s a lot better than the one I had in there. It''s not slipping or anything like that. I had pretty good service with these guys. It shifts pretty good. Eat my shift!

This is Troy Jones, From New Albany Indiana. In 2012 we purchased a transmission from Monster Transmission, A E4OD Heavy Duty for our 7.3 Powerstroke Diesel Truck. We need something that would pull trailers well, and take some abuse. So we had the performance package added on to that, and that’s been a wonderful transmission. I couldn’t have asked for a better company to deal with, and building that transmission for us. And as far as the service, The service along the way was excellent. All the way from trying to choose in the beginning which type of transmission we needed, you know what best suited what we do everyday, and they were wonderful in that process also. Monster Transmission is definitely our go to for our transmission needs in the future, and we definitely recommend Monster Transmission to anyone needing a transmission, be it a regular stock replacement or a performance transmission. Great people to work with. We thank you very much for everything you’ve done to help us, And hopefully our transmission continues to run as strong as it has for the last two years, It’s been wonderful. Thank you.

We recently purchased in 2012, a new E4OD Heavy Duty Transmission for our Powerstroke Diesel. We're not easy on these trucks, these trucks pull a lot of heavy trailers, and equipment, and this transmission has never failed us. It's been super strong, and I couldn't have picked a better company to purchase a transmission from. Even from the mechanicals of the transmission to the service, the whole way of selecting what type of transmission we needed in the first place. Definitely an awesome place to do business with, would definitely recommend you guys to other people in the future. Thank you so much, we appreciate everything you've done for us.
