INSPECTION OF TCM AND ITS CIRCUITS
TCM and its circuits can be checked at TCM wiring couplers by
measuring voltage and resistance.
INSPECTION
1) Remove TCM from vehicle referring to “TRANSMISSION
CONTROL MODULE” in this section.
2) Connect TCM couplers to TCM.
3) Check voltage at each terminal of couplers connected.CAUTION:
TCM cannot be checked by itself, it is strictly prohibited
to connect voltmeter or ohmmeter to TCM with coupler
disconnected from it.
NOTE:
As each terminal voltage is affected by the battery volt-
age, confirm that it is 11 V or more when ignition switch
is ON.

4) Remove output shaft speed sensor (1) and input shaft speed
sensor (2).
5) Remove transmission range sensor (3).
6) Remove dropping resistor (4).
7) Remove breather hose (5).
8) Remove A/T fluid level gauge (1) and filler tube (2).
9) Remove vehicle speed sensor (1) (for speedometer), shift
cable bracket (2) and connector clamp bracket (3).
10) Remove oil pan and oil pan gasket.
11) Remove oil strainer assembly (1), and detach transmission
temperature sensor (2).
NOTE:
 For removal of oil pan, do not turn transmission over
as this will contaminate valve body with foreign materi-
als in the bottom of oil pan.
 When removing oil pan, tap around it lightly with a
plastic hammer. Do not force it off by using a screw-
driver or the like.

7C-2 CLUTCH
GENERAL DESCRIPTION
The clutch is a diaphragm-spring clutch of a dry single disc type. The diaphragm spring is of a tapering-finger
type, which is a solid ring in the outer diameter part, with a series of tapered fingers pointing inward.
The disc, carrying four torsional coil springs, is positioned on the transmission input shaft with an involute spline
fit.
The clutch cover is secured to the flywheel, and carries the diaphragm spring in such a way that the peripheral
edge part of the spring pushes on the pressure plate against the flywheel (with the disc in between), when the
clutch release bearing is held back. This is the engaged condition of the clutch.
Depressing the clutch pedal causes the release bearing to advance and pushes on the tips of the tapered fin-
gers of the diaphragm spring. When this happens, the diaphragm spring pulls the pressure plate away from the
flywheel, thereby interrupting the flow of drive from flywheel through clutch disc to transmission input shaft.
