TROUBLESHOOTING ITEM

DESCRIPTION

PAGE

1

  • Vehicle does not move in D range, or in R position

4

  • Excessive creep

  • Vehicle accelerates in D range, and R position when accelerator pedal is not depressed.

8

  • Does not shift to 6GR

  • Vehicle does not upshift from 5GR to 6GR even though vehicle speed increased.

  • 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 [SJ6A-EL].)

9

  • Abnormal shifting

  • Shifts incorrectly (incorrect shift pattern).

(See NO.9 ABNORMAL SHIFTING [SJ6A-EL].)

10

  • Frequent shifting

  • Downshifting occurs suddenly even when accelerator pedal is depressed slightly in D range.

11

  • Shift point is high or low

  • Shift point considerably different from automatic shift diagram.

  • Shift delays when accelerating.

  • Shift occurs suddenly when accelerating and engine speed does not increase.

12

  • Torque converter clutch (TCC) non-operation

  • TCC does not operate when vehicle reaches TCC operation range.

(See NO.12 TORQUE CONVERTER CLUTCH (TCC) NON-OPERATION [SJ6A-EL].)

13

  • No kickdown

  • Does not downshift when accelerator pedal is fully depressed within kickdown range.

(See NO.13 NO KICKDOWN [SJ6A-EL].)

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 [SJ6A-EL].)

15

  • Engine flares up or slips when accelerating vehicle

  • Engine flares up when accelerator pedal is depressed for upshifting.

  • Engine flares up suddenly when accelerator pedal is depressed for downshifting.

(See NO.15 ENGINE FLARES UP OR SLIPS WHEN ACCELERATING VEHICLE [SJ6A-EL].)

16

  • Judder upon torque converter clutch (TCC) operation

  • Vehicle jolts when TCC is engaged.

(See NO.16 JUDDER UPON TORQUE CONVERTER CLUTCH (TCC) OPERATION [SJ6A-EL].)

17

  • Excessive shift shock from N to D or N to R position/range

  • 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 [SJ6A-EL].)

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 [SJ6A-EL].)

19

  • Excessive shift shock on torque converter clutch (TCC)

  • Strong shock is felt when TCC is engaged.

(See NO.19 EXCESSIVE SHIFT SHOCK ON TORQUE CONVERTER CLUTCH (TCC) [SJ6A-EL].)

20

  • Noise occurs at idle when vehicle is stopped in all positions/ranges

  • Transmission is noisy in all positions and ranges when vehicle is idling.

(See NO.20 NOISE OCCURS AT IDLE WHEN VEHICLE IS STOPPED IN ALL POSITIONS/RANGES [SJ6A-EL].)

21

  • Noise occurs at idle when vehicle is stopped in D range, or in R position

  • Transmission is noisy in driving ranges when vehicle is idling.

(See NO.21 NOISE OCCURS AT IDLE WHEN VEHICLE IS STOPPED IN D RANGE, OR IN R POSITION [SJ6A-EL].)

22

  • No engine braking

  • Engine speed drops to idle but vehicle coasts when accelerator pedal is released during cruising at medium to high speeds.

  • Engine speed drops to idle but vehicle coasts when accelerator pedal is released when in M range (1GR) at low vehicle speed.
