3.If the measurements do not
satisfy the table, check the internal parts in the
transmission according to the procedure below:
(1)
Remove the drain plug (overflow plug) and overflow tube and
then drain fluid (refer to  ).
(2)
Remove the transmission oil pan (refer to GROUP 23B -
Oil Pan and Valve Body Assembly Removal and Installation ).
(3)
Disconnect the input shaft speed sensor connector marked by
the arrow.
(4)
Check the wiring harness between the input shaft speed
sensor connector and the A/T control solenoid valve
assembly connector for open or short circuit, or other
faults.
(5)
Electric continuity should be present between the input
shaft speed sensor-side connector terminals.
4.If
the wiring harness is faulty, replace the transmission
wiring harness as an assembly.
5.If no electric
continuity is present between the input shaft speed sensor
connector terminals, replace the transmission
assembly.
