Manual Road Test
This test check the gear being used in “L”, “2” or “D” range when
driven with unoperated gear shift control system. Test drive vehi-
cle on a level road.
1) Disconnect shift solenoid coupler (1) valves on transmission.
2) With select lever in “P”, start engine and warm it up.
3) With select lever in “L” range, start vehicle and accelerate to
20 km/h (12.5 mile/h). Check in this state that 1st gear is
being used.
4) At 20 km/h (12.5 mile/h), shift select lever to “2” range and
accelerate to 40 km/h (25 mile/h). Check in this state that 3rd
gear is being used.
5) At 40 km/h (25 mile/h), shift select lever to “D” range and
check that O/D gear is used when speed is higher than 40
km/h (25 mile/h).
6) After above checks, stop vehicle then engine, and connect
shift solenoids coupler (1) with ignition switch OFF.
7) Clear DTC with scan tool.
Time Lag Test
This test is to check conditions of clutch, reverse brake and fluid pressure. “Time lag” means time elapsed since
select lever is shifted with engine idling till shock is felt.
1) With chocks placed before and behind front and rear wheels respectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from “N” to “D” range and measure time from that moment till shock
is felt.
4) Similarly measure time lag by shifting select lever from “N“ to “R” range.
Specification for time lag :NOTE:
Before this test, check diagnostic trouble code (DTC).
WARNING:
To avoid the danger of being burned, do not touch the hot
exhaust system when disconnecting shift solenoid cou-
pler (1).
WARNING:
To avoid the danger of being burned, do not touch the hot
exhaust system when connecting shift solenoid coupler
(1).

A/T Throttle Cable
ADJUSTMENT
1) Pull inner cable (3) by force of 2 N (0.2 kg, 0.45 lb) or less to
be no slack of inner cable with A/T throttle cable (1) curved
as shown in the figure.
2) Fix stopper (2) to inner cable (3) with clearance “c”.
A/T throttle cable adjusting position (clearance “c”) :
0.8 – 1.5 mm (0.03 – 0.06 in.)
3) Warm up engine and transmission to normal operating tem-
perature.
4) Make sure that accelerator cable is adjusted as specified.
5) With throttle valve closed, check clearance “c”, which should
be within the following specification, of A/T throttle cable (1).
If it is out of specification, adjust it by turning cable adjusting
nut (2).
A/T throttle cable adjusting position (clearance “c”) :
0.8 – 1.5 mm (0.03 – 0.06 in.)
6) Tighten lock nut (3) securely.
Solenoid Valves (Shift Solenoid Valves and
TCC Solenoid Valve)
INSPECTION
With PCM couplers disconnected and using service wire as
shown in the figure, check each solenoid valve for clicking sound.
Shift solenoid valve - A (#1) C51-1-2
Shift solenoid valve - B (#2) C51-1-1
TCC (Lock-up) solenoid valve C51-1-8

6) After removing shift solenoid valve (A & B) (1), remove sole-
noid valve gasket, low coast modulator valve spring (2), inter
coast modulator valve spring (3) and 2 intermediate coast
modulator valves (4).
7) Pressing TCC (lock-up) control sleeve with finger and using
magnet (1), remove locating pin and then remove TCC (lock-
up) control sleeve, TCC (lock-up) control valve and TCC
(lock-up) control valve spring.
8) Check which step of primary regulator valve sleeve (1) (how
many steps down from its tip) contacts primary regulator
valve sleeve retainer (2).
9) Pressing primary regulator valve sleeve (1) with finger and
using magnet, remove primary regulator valve sleeve
retainer and then remove primary regulator valve sleeve (1),
spacer (2), primary regulator valve plunger (3), primary regu-
lator valve spring (4) and primary regulator valve (5).
