SS Xtreme Mega Monster Transmissions
Engineered to Dominate, the Turbo 400 SS Xtreme 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 1,200 horsepower. Equipped with a Manual valve body or Transbrake, either option, 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 SS Xtreme Mega Monster upshifts and downshifts when you move the shift lever.

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. 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.

**Sonnax Smart-Tech Drum Modules

Sonnax Smart-Tech drum modules for racing GM TH400 transmissions improve on-track performance and consistency, leading to quicker ETs, more wins, and greater reliability. The TH400 is preferred for its overall durability and multitude of available ratios, but is known to be heavier and less efficient than the popular two-speed Powerglide. Part of the TH400 inefficiency results from the fact that the direct drum counter-rotates, spinning backwards in 1st gear, brakes to a complete stop on the 1-2 shift, then goes from 0 RPM to input RPM on the 2-3 shift. Significant energy is wasted through this cycle that robs power, upsets traction on the shifts, and contributes to broken internal parts.

Compared to aluminum direct drums, the Smart-Tech drum module reduces the weight of the counter-rotating components by over 3.3 lbs.! And more significantly, because the weight of the Sonnax counter-rotating parts is closer to the centerline, there's a 68 percent reduction in energy required to stop and restart during the 1-2 and 2-3 shifts. The benefits are increased wheel horsepower, better acceleration, less shock on the shifts, and improved durability.
