Mega Monster Transmissions
Engineered to Dominate, the Turbo 400 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 500 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, 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 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. 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 tail-housing and speedometer gear for your new unit. This Monster 700R4 Transmission does not come equipped with a new Speedometer Gear. Certain vehicle specific tail-housings may not be available with this unit. In most cases, you will be required to swap your original tail-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 tail-housing will need to be reused.



Back in 2011 I bought a Turbo400 from Monster Transmission. Everything's working out really nice. I just ordered a gear for it and changed the speedometer reading. Really I love the company. Very prompt and I enjoyed the Transmission a lot.

I recently purchased a monster transmission, corey helped me out. She was perfect in understanding what I needed, asked the right questions. She walked me through the entire process of ordering, the build and test stages of how the transmission are secured. Charlotte of the tech dept, I was reffered to for the pick up of the transmission, she was extremely helpful. I cant say enough about monster, I highly recommend Monster Transmission. If you ever have transmission troubles Monster Transmissions is the place to go and get them. Great Company, Great People. Again, can’t say enough about this company, I look forward to purchasing all my transmission needs from them in the future. Great job Monster, appreciate you.

I purchased a Monster Transmission for my 1980 3/4 ton Chevy truck and to have it adapted so it can be made up with the 208 transfer case. The staff was excellent. They worked with me to get everything ironed out that needed to be done so that it would fit properly. They got everything ordered, transmission went in, no issue and it has been running great ever since. So excellent job Monster and I tell you what; the customer service with these guys is outstanding.
