AUTOMATIC TRANSAXLE SYMPTOM TROUBLESHOOTING

No.	TROUBLESHOOTING ITEM	DESCRIPTION	PAGE
1	Vehicle does not move in D, 3, 2 ranges, or in R position	Vehicle does not move when accelerator pedal depressed.	(See NO. 1 VEHICLE DOES NOT MOVE IN D, 3, 2 RANGES, OR IN R POSITION .)
2	Vehicle moves in N position	Vehicle creeps in N position. Vehicle creeps if brake pedal 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 locked when P disengaged, vehicle does not move in D, 3, 2 ranges, and R position when accelerator pedal 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, 3, 2 ranges, and R position without depressing accelerator pedal.	(See NO.4 EXCESSIVE CREEP .)
5	No creep at all	Vehicle does not move in D, 3, 2 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 poor at start. Delayed acceleration when accelerator pedal depressed while driving.	(See NO.6 LOW MAXIMUM SPEED AND POOR ACCELERATION .)
7	No shifting	Single shift range only. Sometimes it shifts correctly.	(See NO.7 NO SHIFTING .)
8	Does not shift to fifth gear (5GR)	Vehicle does not upshift from 4GR to 5GR even though vehicle speed increased. Vehicle does not shift to 5GR even though accelerator pedal released in D range at 60 km/h {37 mph} .	(See NO.8 DOES NOT SHIFT TO FIFTH GEAR (5GR) .)
9	Abnormal shifting	Shifts incorrectly (incorrect shift pattern).	(See NO.9 ABNORMAL SHIFTING .)
10	Frequent shifting	Downshifting occurs immediately even when accelerator pedal depressed slightly in D, 3,2 ranges except O/D OFF mode.	(See NO.10 FREQUENT SHIFTING .)
11	Shift point is high or low	Shift point considerably different from automatic shift diagram. Shift delays when accelerating. Shift occurs quickly when accelerating and engine speed does not increase.	(See NO.11 SHIFT POINT IS HIGH OR LOW .)
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 .)
13	No kickdown	Does not downshift when accelerator pedal fully depressed within kickdown range.	(See NO.13 NO KICKDOWN .)
14	Engine flares up or slips when upshifting or downshifting	When accelerator pedal depressed for driveway, engine speed increases but vehicle speed increase slowly. When accelerator pedal 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 depressed for upshifting. Engine flares up suddenly when accelerator pedal depressed for downshifting.	(See NO.15 ENGINE FLARES UP OR SLIPS WHEN ACCELERATING VEHICLE .)
16	Judder upon torque converter clutch (TCC) operation	Vehicle jolts when TCC engaged.	(See NO.16 JUDDER UPON TORQUE CONVERTER CLUTCH (TCC) OPERATION .)
17	Excessive shift shock from N to D or N to R position/range	Strong shock 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 felt when depressing accelerator pedal to accelerate at upshifting. During cruising, excessive shift shock felt when depressing accelerator pedal at downshifting.	(See NO.18 EXCESSIVE SHIFT SHOCK IS GIVEN WHEN UPSHIFTING AND DOWNSHIFTING .)
19	Excessive shift shock on torque converter clutch (TCC)	Strong shock felt when TCC engaged.	(See NO.19 EXCESSIVE SHIFT SHOCK ON TORQUE CONVERTER CLUTCH (TCC) .)
20	Noise occurs at idle when vehicle is stopped in all positions/ranges	Transaxle noisy in all positions and ranges when vehicle idling.	(See NO.20 NOISE OCCURS AT IDLE WHEN VEHICLE IS STOPPED IN ALL POSITIONS/RANGES .)
21	Noise occurs at idle when vehicle is stopped in D, 3, 2 ranges, or in R position	Transaxle noisy in driving ranges when vehicle idling.	(See NO.21 NOISE OCCURS AT IDLE WHEN VEHICLE IS STOPPED IN D, 3, 2 RANGES, OR IN R POSITION .)
22	No engine braking in 2 range	Engine speed drops to idle but vehicle coasts when accelerator pedal released during cruising at medium to high speeds. Engine speed drops to idle but vehicle coasts when accelerator pedal released when in 2 range at low vehicle speed.	(See NO.22 NO ENGINE BRAKING IN 2 RANGE .)
23	Transaxle overheats	Burnt smell emitted from transaxle. Smoke emitted from transaxle.	(See NO.23 TRANSAXLE OVERHEATS .)
24	Engine stalls when shifted to D, 3, 2 ranges, or in R position	Engine stalls when shifting from N or P position to D, 3, 2 ranges or R position at idle.	(See NO.24 ENGINE STALLS WHEN SHIFTED TO D, 3, 2 RANGES, OR IN R POSITION .)
25	Engine stalls when driving at slow speeds or stopping	Engine stalls when brake pedal depressed while driving at low speed or stopping.	(See NO.25 ENGINE STALLS WHEN DRIVING AT SLOW SPEEDS OR STOPPING .)
26	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 turned on and ignition switch at ON.	(See NO.26 O/D OFF INDICATOR LIGHT DOES NOT ILLUMINATE WHEN O/D OFF SWITCH IS TURNED ON .)
27	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 turned off and ignition switch at ON.	(See NO.27 O/D OFF INDICATOR LIGHT ILLUMINATES WHEN O/D OFF SWITCH IS NOT TURNED ON .)
