Its a double shift box

push the button down and push the

lever to the left that will give you the first 8 gears

using the lever as a 2 speed box

then pull the button up and the lever to the left then go back to what was first gear,

this will give you the other 8 gears, using the same method

Each gear has a split to give you half a gear small button on gear lever.You start with gear lever pushed over to the left and have standard 1 forward 2 back 3 forward 4 back shift stick to neutral pull gear lever to the right which shifts into high range then you have 5 forward 6back 7 forward 8 back so with the split you have 16 gears.Never hold the gear lever in 7 when pulling up an incline as it fu*ks up the 3/7 syncro in no time
