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 450 horsepower (900 trq). The Mega Monster is recommended for any type of heavy towing or plowing use around 8,500lbs! 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. This custom built transmission is highly recommended for any type of vehicles that have larger tires and are lifted.

*Included with your Black Beast Diesel E40D Transmission is a 1405 Hayden Transmission Cooler Kit.

I received a transmission for my F350 Ford. The E4OD. So far so good. We installed it a couple weeks ago. Service, getting back to was fine. So far it's definitely quite the wait. I mean, I waited for it, I'm glad I did. Was going to go somewhere else, but I'm glad I didn't. Anyways that's about it, so far so good and thanks for your services.
Verified Buyer: 
I purchased a transmission from Monster Transmission for my 1994 Ford 350, and so far everything's worked great. I did have to change the extension on the back of the transmission. I put my old one on. There seemed to be a little tiny hairline crack on the one I received from Monster Transmission, but all in all it's well. I changed that over, and don't know if it was something I did putting it in, or something a tech did when they were tightening down the bolts.. but anyhow... it's working great, fits nice, everything is smooth, and I look forward to doing more purchases from Monster Transmission for any of my vehicles. Thanks, bye
