Mega Monster Transmissions
Engineered to Dominate, the 700R4 Mega Monster Corvette transmission is tough enough to withstand the rigors of even the toughest Corvettes delivering tire-spinning shifts race after race. It is ideal for Corvettes powered by engines producing up to 500 horsepower(450tq) with a naturally aspirated system 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.


The 700R4 has a 3.06 ratio in first gear, which is 20% lower than most transmissions. The 30% overdrive will give a 30 to 40% increase in gas mileage on the road when compared to a 3-speed transmission. The 700R4 is a popular transmission swap for muscle car restorations to add the overdrive option & to update to a modern transmission. Converting from a Turbo 350 or Turbo 400 3-speed to the 700R4 Monster transmission may also increase the value of your vehicle.

*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.

I ordered a 700 R4 transmission with heavy duty performance and it came with the 23-2500 stall convertor with lock up and level 2 was my shift preference and it came as advertised, it came undamaged the box was in great shape, it was well packaged and the installation went in without a hitch, it is going into a factory Corvette and as a matter of fact I just installed it the other day and I got a few more days probably before I can fire everything up and give it its first test run, couldn’t be happier with the service that I have gotten and once I get it up and running I'll get it on the road, take some photographs will shoot it off, I have just got off the phone to Wyatt as I had to order a couple of other accessories for it and that also went smoothly so much appreciate the help Monster Transmission.

Your prices are great, the quality of what you got is super good and we''re really pleased with it.
I bought my transmission about 11 months ago. We are in the process of the final installation in the car. We want to paint it a different color and I needed a Monster label or sticker to put on it because we want to show it off. We think the quality of this transmission is super good and you guys have a great reputation in this part of Texas. For the next car we build, I guarantee we will be coming to you for a transmission. Your prices are great, the quality of what you got is super good and we''re really pleased with it. Thanks a lot guys.

I had the best experience with Monster Transmission
I had the best experience with Monster Transmission. They guy who took care of me was such a professional man. He made it easy, my transmission was smooth, and everything about getting a new transmission for my truck was made so easy. I would tell anybody: if you want a transmission and you want it done right, they ask the right questions and they stick with you the whole time until you get it. Trust me, get a Monster Transmission. It is worth it. Thanks for such a great experience!

The Monster Transmission staff are fantastic!
The Monster Transmission staff are fantastic! They are a great help. My transmission arrived almost 3 or 4 days early. I went to a shop to have it installed and everything works fantastic. I love my transmission. It is really fantastic. I will have to figure out my gas mileage later but I believe that I am getting a better fuel economy, which in this day and time means a lot. I really am hoping that we get that extra few miles per gallon. Thank you very much Monster Trans, you have been fantastic! I really love it. Thank you!
