try shifting without the clutch. as you let off the gas shift and as the engine is slowing down to about the speed of the next gear shift into the next gear...takes a bit...but old road rangers shift best without the clutch and learning your engine speed... in other words the diesel say wound out at 2200 or so...then drops down to 1800 or so for next gear....its hard to explain... have some old truck driver show you how to shift without the clutch... well except for starting like they said...its uhhhhhhhh sort of like driving and shifting a two speed rear end.... only the rpms have to be close....
