7B-10 AUTOMATIC TRANSMISSION (4 A/T)
CHANGE MECHANISM
The same select pattern shift lever is used as the floor type and
frequently used “N” and “D” ranges are made selectable freely. Throttle position
signal circuit
(DTC P1700)No or abnormal throt-
tle opening signal is
inputtedScheduling of automatic gear shift is performed as throttle
valve opening is 0%.
Control of automatic gear shift (i.e. control of oil pressure) is
performed as throttle valve opening is 100%.
Coast down shifting is performed when brake is applied and
engine rev. is less than 1,500 rpm.
Lock-up function is turned OFF.

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.
