GENERAL DESCRIPTION
This automatic transmission is a full automatic type with 3-speed plus overdrive (O / D).
The torque converter is a 3-element, 1-step and 2-phase type and is equipped with an electronically controlled
lock-up mechanism. The gear shift device consists of 3 sets of planetary gear units, 3 disc type clutches, 4 disc
type brakes and 3 one-way clutches. The gear shift is done by selecting one of 6 positions (ªPº, ªRº, ªNº, ªDº, ª2º
and ªLº) by means of the select lever installed on the floor. On the shift knob, there is an overdrive (O / D) cut switch
which allows shift-up to the overdrive mode (except at 4L) and shift-down from the overdrive mode. Also, by using
the P / N change switch located on the console box, it is possible to select the gear change timing of 2 modes, nor-
mal and power.

AUTOMATIC GEAR SHIFT DIAGRAM
Automatic shift schedule as a result of shift control is shown below. In case that select lever is shifted to L at a higher
than 52 km / h or 33 mile / h speed for G16 engine (45 km / h or 28 mile / h for J20 engine, 55 km / h or 34 mile / h for
H25 engine), 2nd or 3rd gear is operated and then down shifts to 1st at a speed lower than that. No up shift is
available in L.
The same as, the select lever is shifted to 2 at a higher than 102 km/h (64 mile/h) speed for G16/J20 engines (105
km / h or 65 mile / h for H25 engine), 3rd gear is operated and then down shifts to 2nd at a speed lower than that.

TROUBLESHOOTING
WARNING:

When performing a road test, select a place where there is no traffic or possibility of a traffic accident
and very careful during testing to avoid occurrence of an accident.

Road test should be carried out with 2 person, a driver and tester, on a level road.
STEPACTIONYESNO
1Was ªAUTOMATIC TRANSMISSION
DIAGNOSTIC FLOW TABLEº performed?Go to Step 2.Go to ªAUTOMATIC

DIAGNOSTIC FLOW
TABLEº.
2ECT check:
(1) Warm up engine to normal operating
temperature.
(2) Check ECT using scan tool.
Is ECT more than 30C (86F)?Go to Step 3.Faulty ECT sensor,
its circuit or engine
cooling system.
If OK, substitute a known-
good PCM and recheck.
3Perform running test under the following
conditions and check voltage between
C51-1-2 (G16 / J20 engines) or C51-1-6 (H25
engine) terminal of PCM coupler and ground,
C51-1-1 terminal of PCM coupler and ground.

O / D cut switch OFF (ªO / D OFFº lamp OFF).

Normal mode in ªDº range.

Transfer ª2Hº position.

Cruise control is not operated (if equipped).

Drive vehicle with 4th gear condition
referring to ªGear shift diagramº in this
section.
Is each voltage about 0 V?Faulty shift solenoid
valve, its circuit or
transmission.ªGº wire or ªG / Rº wire
shorted to power circuit.
If OK, go to Step 4.
4O / D cut switch signal inspection:
(1) With ignition switch ON, check voltage
between E61-33 (G16 / J20 engines) or
E61-14 (H25 engine) terminal of PCM
coupler and ground.
Is the result as specified?Go to Step 5.Faulty O / D cut switch or
its circuit.
If OK, substitute a known-
good PCM and recheck.
