Description
#
Trouble
1
Will start in other than P and N range
Engine starts in P, N, and other ranges
2
Engine stalls
Idle when shifted from
N or P to other ranges
Engine stops unexpectedly when shifted from N or P to
other ranges at idle
3
On deceleration
Engine stops unexpectedly at beginning of deceleration or
recovery from deceleration exhaust afterburn
4
Engine rough
On deceleration
Engine shakes at beginning of deceleration, during
deceleration, or recovery from deceleration
5
Poor acceleration
At drive-away
Engine speed increases normally but vehicle speed slowly
increases during drive-away
6
On acceleration
Engine speed increases normally but vehicle speed slowly
increases during acceleration
7
Surges while cruising
Momentary minor irregularity in engine output at steady
vehicle speed
8
Lack of power
Performance poor under load (i. e., power down when
climbing hills)
9
Poor fuel economy
Fuel economy unsatisfactory
10
Vehicle does not move in D, 2, 1 and/or R
range
No creep at all
Vehicle does not move when accelerator pedal depressed
after shifted to D, 2, 1 and/or R range
11
Vehicle moves in N range
Vehicle creeps in N range
Vehicle moves when accelrator pedal not depressed
12
Vehicle moves in P range
Vehicle rolls in P range
13
Excessive creep
Vehicle moves quickly in D, 2, 1 and R range (accelerator
pedal not depressed)
Excessive N to R range and N to D range shift shock
felt
14
No shift
Single range shift (1GR→2GR, 2GR→3GR, or 3GR→O/D)
only Sometimes shifts correctly
Gear position held in O/D OFF mode
15
Abnormal shift
Shifts incorrectly (incorrect shift pattern)
Example : vehicle shifts 1GR→O/D directly when
accelerating with accelerator pedal depressed slightly
16
Frequent shifting
Downshift occurs when accelerator depressed slightly in D,
S or 2 and L or 1 ranges (except hold mode)
17
Shift point high or low
Shift points do not match shift diagram
Shift delayed when accelerating
Shifts occur too fast when accelerating and engine speed
does not increases
18
No lock-up
No lock-up when vehicle speed reaches lock-up range
