Invest in a Monster Transmission and make your Opponent "EAT YOUR SHIFT!"

SS Mega Monster Transmissions
Engineered to Dominate, the Big Block C6 SS Mega Monster transmission is tough enough to withstand the rigors of even the toughest street machines delivering tire-spinning shifts race after race. It is ideal for vehicles powered by engines producing up to 800 horsepower using pump gasoline. 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. 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 SS 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..

Monster''s transmissions perform flawlessly
I am with the Clay County 4x4 Club. We also host a regional offroad competition. My truck is used for recovery duty during this event and for general play. When I needed a transmission, I called the best in the business. I called Monster and I got the Monster Mega C6 SS. I have pulled vehicles a quarter mile uphill and I have drug everything you can think of. Monster''s transmissions perform flawlessly. I couldn''t ask for any better as far as dependibility. It stays cool and it''s very dependible.
Verified Buyer: 
I purchased a C6 Transmission SS for my 1985 Ford Bronco with a 557 cubic inch motor. I also had it vizikoated with the 100 dollar bill patterns, I think that the transmission looks awesome, everybody that looks at it just loves it. Also, Mr. Javier was my salesman. He was an awesome person to work with. Monster Transmissions did an outstanding job, they built what I wanted. I've called Monster Transmissions a few times and they were always polite, professional, and if I ever have another transmission that needs to be done again I'll definitely get with Monster Transmissions to have it done. And I will also get the vizikoat again. They have plenty of patterns. Everybody should be able to chose a pattern, find what they want.. it's on there, professional, it's not coming off. Everybody that looks at this transmission just loves it, so I appreciate it, thank you, and have a good day.
