Road Test

NOTE: This test determines if shift control system is functioning properly.
  1. Check minimum throttle upshifts in overdrive. Transmission should start in 1st gear and shift automatically into and through each gear at pre-determined specifications. See SHIFT SPEEDS (MPH) .
  2. With transmission in 4th gear (overdrive), depress overdrive cancel switch. Transmission should downshift to 3rd gear.
  3. Depress accelerator pedal to floor (WOT). Transmission should downshift from 3rd to 2nd or 1st gear, depending on vehicle speed. See SHIFT SPEEDS (MPH) .
  4. When traveling above 50 MPH at less than half throttle, move transmission from Overdrive to 2nd gear and release accelerator pedal. Transmission should immediately downshift into 2nd gear. With vehicle in 2nd gear, move selector to 1st gear and release accelerator pedal. Transmission should downshift to 1st gear at less than 30-35 MPH.
