OVERVIEW

The lightweight 3MO TXL 6 Speed 4WD Sequential Gearbox suits racing engines using longitudinally orientated, front or mid mounted engines, connected to a four wheel drive differential setup. Race car owners spend a lot of time and money taking weight out of their cars, so it makes no sense adding that weight back with a heavy or over specified gearbox that’s not fit for purpose. The transmission’s compact size means driveline tunnels don’t usually need to be modified making fitting simple and easy in a wide range of situations. If you have 600nm or less, then the TXL lightweight and super quick shifting sequential gearbox is probably the right choice for you.

This versatile 3MO sequential gearbox has a wide range of 35 gear ratios and 3 driven shaft ratios to choose from ensuring drivers can specify the gearbox at ordering time for their unique needs – in other words; there’s a gear ratio for almost every situation. The TXL 6 Speed Sequential Gearbox is capable of handling engine torque of 600 Nm or 450 lb/ft with 1st gear @ 3.08 and 0.97 input drive (25 x 24) i.e. 2.98. If a taller 1st gear ratio of 2.92 and 0.87 input drive (23 x 20) i.e. 2.54 are chosen; then torque capability is reduced to 520 Nm or 385 lb/ft

There are three inspection ports to allow for easy checking of the dog rings without disassembling the gearbox, which saves workshop time.

With proper shift technique and lubrication, dog rings should be good for 60 hours of racing or 8400 km / 5250 miles. Likewise, gear positions 2 and 3 are rated for 50 hours or 7000 km / 4375 miles, with gear positions 4, 5 and 6 being rated for 75 hours or 10500 km / 6560 miles
