  • Vehicle does not shift to 6GR even though accelerator pedal is released in D range at 80 km/h {50 mph}.
(See NO. 8 DOES NOT SHIFT TO 6GR .)
9
  • Abnormal shifting
  • Shifts incorrectly (incorrect shift pattern).
(See NO. 9 ABNORMAL SHIFTING .)
10
  • Frequent shifting

(See NO. 13 NO KICKDOWN .)
14
  • Engine flares up or slips when upshifting or downshifting
  • When accelerator pedal is depressed, engine speed increases normally but vehicle speed increases slowly.
  • When accelerator pedal is depressed while driving, engine speed increases but vehicle speed does not increase.
(See NO. 14 ENGINE FLARES UP OR SLIPS WHEN UPSHIFTING OR DOWNSHIFTING .)
15
  • Engine flares up or slips when accelerating vehicle
  • Engine flares up when accelerator pedal is depressed for upshifting.

  • Strong shock is felt when shifting from N to D or N to R position/range at idle.
(See NO. 17 EXCESSIVE SHIFT SHOCK FROM N TO D OR N TO R POSITION/RANGE .)
18
  • Excessive shift shock is given when upshifting and downshifting
  • Excessive shift shock is felt when depressing accelerator pedal to accelerate at upshifting.
  • During cruising, excessive shift shock is felt when depressing accelerator pedal at downshifting.
(See NO. 18 EXCESSIVE SHIFT SHOCK IS GIVEN WHEN UPSHIFTING AND DOWNSHIFTING .)
