Low or dirty fluid is the #1 cause of erratic shifting. He topped it off with the specific synthetic blend his rig required, which helped lubricate the internal clutches and smoothed out the hydraulic pressure. Step 2: The "Ghost in the Machine" jerking trannie

Elias was hauling a full load of timber through the pass when he felt it: a sharp, rhythmic jerk every time the truck tried to upshift. It felt like the engine was hiccuping, and the tachometer needle was bouncing erratically. Most drivers might have pushed through, but Elias knew that a "jerking" transmission is a truck’s way of screaming for help.
