Use the chart below to verify the symptoms of the trouble in order to diagnose the appropriate area.

DIAGNOSTIC INDEX

No.	TROUBLESHOOTING ITEM	DESCRIPTION	REFERENCE
1	Vehicle does not move in D, 2,1 ranges, or in R position	Vehicle does not move when accelerator pedal is depressed.	(See NO. 1 VEHICLE DOES NOT MOVE IN D, 2,1 RANGES, OR IN R POSITION )
2	Vehicle moves in N position	Vehicle creeps in N position. Vehicle creeps if brake pedal is not depressed in N position.	(See NO. 2 VEHICLE MOVES IN N POSITION . )
3	Vehicle moves in P position, or parking gear does not disengage when P is disengaged	Vehicle rolls when on a downward slope and tires do not lock in P position. Tires are locked when P is disengaged, vehicle does not move in D, 2, 1 ranges, and R position when accelerator pedal is depressed, and engine remains in stall condition.	(See NO. 3 VEHICLE MOVES IN P POSITION, OR PARKING GEAR DOES NOT DISENGAGE WHEN P IS DISENGAGED )
4	Excessive creep	Vehicle accelerates in D, 2, 1 ranges, and R position without depressing accelerator pedal.	(See NO. 4 EXCESSIVE CREEP . )
5	No creep at all	Vehicle does not move in D, 2, 1 ranges, or R position when idling on flat paved road.	(See NO. 5 NO CREEP AT ALL . )
6	Low maximum speed and poor acceleration	Vehicle acceleration is poor at start. Delayed acceleration when accelerator is depressed while driving.	(See NO. 6 LOW MAXIMUM SPEED AND POOR ACCELERATION . )
7	No shift	Single shift range only. Sometimes shifts correctly.	(See NO. 7 NO SHIFT . )
8	No TCC function	TCC does not operate even though vehicle speed is increased.	(See NO. 8 NO TCC FUNCTION . )
9	Abnormal shift	Shifts incorrectly (incorrect shift pattern).	(See NO. 9 ABNORMAL SHIFT . )
10	Frequent shifting	Downshifting occurs immediately even when accelerator pedal is depressed slightly in D, 2,1 ranges (O/D OFF switch is off).	(See NO. 10 FREQUENT SHIFTING . )
11	Shift point is high or low	Shift point is considerably different from automatic shift diagram. Shift is delayed when accelerating. Shift occurs quickly when accelerating and engine speed does not increase.	(See NO. 11 SHIFT POINT IS HIGH OR LOW . )
12	No kickdown	Does not downshift when accelerator pedal is fully depressed within kickdown range.	(See NO. 12 NO KICKDOWN . )
13	Engine flares up or slips when upshifting or downshifting	When accelerator pedal is depressed for driveway, engine speed increases but vehicle speed increase slowly. When accelerator pedal is depressed while driving, engine speed increases but vehicle speed does not increase.	(See NO. 13 ENGINE FLARES UP OR SLIPS WHEN UPSHIFTING OR DOWNSHIFTING . )
14	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. 14 ENGINE FLARES UP OR SLIPS WHEN ACCELERATING VEHICLE . )
15	Judder upon TCC operation	Vehicle jolts when TCC is engaged.	(See NO. 15 JUDDER UPON TCC OPERATION . )
16	Excessive N to D or N to R position/range shift shock	Strong shock is felt when shifting from N to D or N to R position/range at idle.	(See NO. 16 EXCESSIVE N TO D OR N TO R POSITION/RANGE SHIFT SHOCK )
17	Excessive shift shock 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. 17 EXCESSIVE SHIFT SHOCK WHEN UPSHIFTING AND DOWNSHIFTING )
18	Excessive TCC shift shock	Strong shock is felt when torque converter clutch is engaged.	(See NO. 18 EXCESSIVE TCC SHIFT SHOCK )
19	Noise at idle when vehicle is stopped in all position/ranges	Transmission is noisy in all positions and ranges when vehicle is idling.	(See NO. 19 NOISE AT IDLE WHEN VEHICLE IS STOPPED IN ALL POSITION/RANGES )
20	Noise at idle when vehicle is stopped in D, 2,1 ranges, or in R position	Transmission is noisy in driving ranges when vehicle is idling.	(See NO. 20 NOISE AT IDLE WHEN VEHICLE IS STOPPED IN D, 2, 1 RANGES OR IN R POSITION )
21	No engine braking in 1,2, or 3 gear	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 in. 1 range at low vehicle speed.	(See NO. 21 NO ENGINE BRAKING IN 1, 2, OR 3 GEAR )
22	Transmission overheats	Burnt smell is emitted from transmission. Smoke is emitted from transmission.	(See NO. 22 TRANSMISSION OVERHEATS )
23	Engine stalls when shifted to D, 2, 1 ranges, and/or in R position	Engine stalls when shifting from N or P position to D, 2,1 ranges or R position at idle.	(See NO. 23 ENGINE STALLS WHEN SHIFTED TO D, 2,1 RANGES, AND/OR IN R POSITION )
24	Engine stalls when driving at slow speeds or stopping	Engine stalls when brake pedal is depressed while driving at low speeds or stopping.	(See NO. 24 ENGINE STALLS WHEN DRIVING AT SLOW SPEEDS OR STOPPING )
25	O/D OFF indicator light does not illuminate when O/D OFF switch is turned on	O/D OFF indicator light in dashboard does not illuminate when O/D OFF switch is turned on and ignition switch is at ON.	(See NO. 25 O/D OFF INDICATOR LIGHT DOES NOT ILLUMINATE WHEN O/D OFF SWITCH IS TURNED ON )
26	O/D OFF indicator light illuminates when O/D OFF switch is not turned on	O/D OFF indicator light in dashboard illuminates even though O/D OFF switch is turned off and ignition switch is at ON.	(See NO. 26 O/D OFF INDICATOR LIGHT ILLUMINATES WHEN O/D OFF SWITCH IS NOT TURNED ON )
