what you need to do is float shift the gears , keep your foot off the clutch older heavy trucks transmissions arn't constant mesh trannys, put the truck in gear and build the rpm up to between 1900 and 2000,at the same time, pull the stick out of gear and slack off the throttle as you let the rpms drop to around 1500, position the stick in the gate for the next gear,use very light pressure, when the engine rpm matches the road speed of the truck for that next gear, it will drop right in, go up thru the lower gears the same way then pull the range select switch to direct while in 5th gear, shift to 6th, again when it all gets matched it will drop right in, run up the rpms, with the splitter switch in direct then move it to overdrive slack off the throttle and you'll feel the "bump" when it shifts the gear,some call this 6th over, some call it 7th, your call, after you run up the rpms, shift the stick as before, but after you get the stick in the next gear and before you mash the throttle , switch the splitter to direct, try this with the rig empty on a level road and shift around 1900, it will be a little easier, once youve masterd this, [ and it wont take very long] life will be easier, NOTE, one thing you must not do, never shift the splitter with the stick in nutural while moving,if you do, you must bring the rig to a stop with the brakes and start over, floating the gears works well but only if one end of the tranny or the other is in mesh, if you accidently do the above, you have in effect taken both ends of the tranny out of gear at the same time and you cannot "catch " the gears untill you stop, hope this helps, i drive a 13 speed all day everyday
