Hi! Thanks for using my mod!

This Twin Stick Gearboxes were made out of 2 gearboxes: The main gearbox (5 or 6 speed)
and the aux gearbox (4 speed: low, under, direct and overdrive).

These gearboxes are difficult to drive as they have some useless ratios:

TRQ-720 Quadruplex 5x4 (20 gears) ratios:

        [R1]: -13.63    Low
	[R2]: -6.41     Under
	[R3]: -5.45     Direct
	[R4]: -4.62     Overdrive
	
        [1ST]: 13.63    1st Low

You must get used to the gearbox depending on your driving style! 
For example, I like to follow this patern when driving my 24 speed gearbox:

1, 2, 3, 4, 6, 7, 8, 10, 11, 12, 15, 16, 19, 20, 23, 24

There you have some usefull links if you want to learn how to drive these gearboxes with
2 h-shifters:
