Shocks when changing from N to D and large time
lag If abnormal shocks or a time lag of 2
seconds or more occur when the selector lever is shifted from N to D
range while the engine is idling, the cause is probably abnormal
underdrive clutch pressure or a malfunction of the underdrive
clutch, valve body.

Shocks when changing from N to R and large time
lag If abnormal shocks or a time lag of 2
seconds or more occur when the selector lever is shifted from N to R
range while the engine is idling, the cause is probably abnormal
reverse clutch pressure or low and reverse brake pressure, or a
malfunction of the reverse clutch, low and reverse brake, valve body
or idle position switch.

Shocks when changing from N to D, N to R and large time
lag If abnormal shocks or a time lag of 2
seconds or more occur when the selector lever is shifted from N to D
range and from N to R range while the engine is idling, the cause is
probably abnormal line pressure or a malfunction of the oil pump or
valve body.

Malfunction when
shifting
|
Shocks and running up If
shocks occur when driving due to upshifting or downshifting and the
transmission speed becomes higher than the engine speed, the cause
is probably abnormal line pressure or a malfunction of a solenoid
valve, oil pump, valve body, brake or clutch.

body | |
Does not
shift
|
No diagnosis codes If shifting
does not occur while driving and no diagnosis codes are set, the
cause is probably a malfunction of the transaxle range switch, or
TCM
