7B-20 AUTOMATIC TRANSMISSION (4 A/T)
STALL TEST
This test is to check overall performance of automatic transmis-
sion and engine by measuring stall speed at “D” and “R” ranges.
Be sure to perform this test only when transmission fluid is at nor-
mal operating temperature and its level is between FULL and
LOW marks.
1) Apply parking brake and block wheels.
2) Install tachometer.
3) Start engine with select lever shifted to “P”.
4) Depress brake pedal fully.
5) Shift select lever to “D” and depress accelerator pedal fully
while watching tachometer. Read engine rpm quickly when it
has become constant (stall speed).
6) Release accelerator pedal immediately after stall speed is
checked.
7) In the same way, check stall speed in “R” range.
8) Stall speed should be within following specification.
Stall speed
: 2,750 – 3,150 r/min CAUTION:
 Do not run engine at stall more than 5 seconds contin-
uously, for fluid temperature may rise excessively
high.
 After performing stall test, be sure to leave engine run-
ning at idle for longer than 30 seconds before another
stall test.

DTC P0741 (DTC NO.29) TCC (LOCK-UP) SOLENOID PERFORMANCE OR STUCK OFF
Step Action Yes No
1Was “AUTOMATIC TRANSMISSION DIAG-
NOSTIC FLOW TABLE” performed?Go to Step 2. Go to “AUTOMATIC
TRANSMISSION DIAG-
NOSTIC FLOW TABLE”.
2 Check TCC (lock-up) solenoid referring to
“SHIFT SOLENOID VALVES” in this section.
Is it in good condition?Go to Step 3. Replace TCC (lock-up)
solenoid.
3 Check valve body for fluid passage clog, or
lock-up control valve, secondary regulator valve
or signal valve stuck, referring to “TRANSMIS-
SION UNIT REPAIR OVERHAUL” in this sec-
tion.
Are they in good condition?Go to Step 4. Faulty valve body.
4 Substitute a known-good torque converter and
recheck.
Is it OK?Torque converter mal-
function.Overhaul and repair auto-
matic transmission.
DTC DETECTING CONDITION
Difference between turbine rev. and engine rev. too close even though TCM ordered to turn OFF lock-up.
Difference between turbine rev. and engine rev. too wide even though TCM ordered to turn ON lock-up.

FLUID LEVEL AT ROOM TEMPERATURE
INSPECTION
The fluid level check at room temperature performed after repair
or fluid change before test driving is just preparation for level
check of normal operation temperature. The checking procedure
itself is the same as that described previously. If the fluid level is
between FULL COLD and LOW COLD, proceed to test drive. And
when the fluid temperature has reached the normal operating
temperature, check fluid again and adjust it as necessary.
FLUID CHANGE
1) Lift up vehicle.
2) When engine has cooled down, remove drain plug (1) from
oil pan and drain A/T fluid.
3) Install drain plug.
