1) When you are upshifting or downshifting multiple gears at once, you will need to use the high or low buttons to select the appropriate range before you move the gearshift lever. For example, if you want to shift from 3rd gear in high to 6th gear in low, you would first press the low button and then move the gearshift lever from 3rd to 6th.
2) When you are coming to a stop, it is important to downshift into low range before you stop completely. This will help to prevent the transmission from grinding when you start up again.
Here are some additional tips for using an 18-speed transmission:
-Always start the truck in 1st gear. This will help to reduce wear and tear on the transmission.
-Shift gears smoothly and avoid jerking the gearshift lever. This can also help to prolong the life of your transmission.
-Listen for any unusual sounds coming from the transmission. If you hear anything strange, have your truck checked out by a mechanic as soon as possible.
-Have the transmission fluid checked and changed regularly according to the manufacturer's recommendations.
