Troubleshooting Flowchart for "No Movement"

Scenario: The engine runs, you select "D," but the bus does not move. Key Features and Engineering Brilliance Why did ZF

  1. Check ATF level – Engine running, transmission warm, selector in "N." Low fluid is the #1 cause.
  2. Check the selector module – Does the "D" appear on the dash? If not, the CAN signal is lost.
  3. Listen for the pump – Place a screwdriver on the transmission case. Do you hear whirring? No sound = failed primary pump.
  4. Check parking pawl – Sometimes the mechanical pawl jams. Rock the vehicle violently while shifting from P to R to N to D.
