The 3MO TXB 6 Speed 900 Nm / 665 lb-ft Sequential Gearbox suits race and high performance street vehicles where the engine is longitudinally mounted in the front or mid positions, and driven through a rear wheel differential. This sequential transmission features a drop gear system with 4 ratio choices which can be changed in 10 minutes without needing to remove the gearbox from the vehicle. The Drop Gear System allows fine tuning of ratios on race day, and eliminates having to change rear differentials out during the week just to setup for a different track next weekend.

With 52 gear ratios to choose from, the dog speed delta between gears can be optimised for lightening quick and almost imperceptible gear shifts keeping the power to the track for the maximum amount of time. When combined with the 3 different drop gear options, there's a setup for almost every situation. This highly reliable and precision engineered sequential gearbox delivers ~97% efficiency.

This TXB gearbox is rated for engine torque of 900 Nm / 665 lb ft in Circuit Racing, Road Racing and Rally applications. In a Drifting application, this 6 Speed sequential transmission is capable of handling engine torque of 1400 Nm.
