|
|
|
2
|

|
Vehicle does not move in D, 2, 1 ranges, or R position when idling on flat paved road.
|
|
|
6
|
Low maximum speed and poor acceleration
|
Vehicle acceleration is poor at start.
Delayed acceleration when accelerator pedal is depressed while driving.

|
|
|
9
|

|
Shifts incorrectly (incorrect shift pattern).
|
|
|
10
|

|
|
|
11
|
Shift point is high or low
|

Shift delays when accelerating.
Shift occurs suddenly when accelerating and engine speed does not increase.
|
|
|
12
|

|
TCC does not operate when vehicle reaches TCC operation range.
|
|
|
13
|

|
|
14
|
Engine flares up or slips when upshifting or downshifting

|
|
|
15
|
Engine flares up or slips when accelerating vehicle
|

|
|
|
18
|
Excessive shift shock is felt 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.
|
|
|
19
|
Excessive shift shock on torque converter clutch (TCC)
|

|
|
20
|
Noise occurs at idle when vehicle is stopped in all positions/ranges
|

|
|
22
|
No engine braking in 1 range and 2 range (2GR)
|
