TURBINE SENSOR
The turbine sensor is attached to the right side of the
transmission.

Inspect
1. During the driving at speed of 20km/h (12mph) with
“L” range in low gear, measure the voltage between
the TCM connector terminals (B3) and (B5) with a
digital voltmeter.
Standard voltage : approx. 7V (AC range)
2. If the voltage is out of the standard value, check the
turbine sensor pole piece for presence of foreign
materials and the turbine sensor cable for short o
r
open circuit.

FLUSHING THE TRANSMISSION FLUID COOLER AND LINE
The fluid cooler and lines may be flushed under the
following condition. This will help prevent more trouble
after the transmission is repaired.
1. When the abnormal amount of debris are found.
2. When the abnormal wear or chips on gears and
shafts are found while overhauling.
3. When the abnormal clutch facing wear and oil
contamination are found.

Procedures
1. Block the wheels.
2. Disconnect negative battery cable.
3. Raise vehicle and support with suitable safety
stands.
4. Disconnect fluid cooler lines at transmission case
and fluid cooler.
5. Flush and back-flush the fluid cooler and lines using
solvent and compressed air.
Note:
DO NOT exceed 197 kPa (29 psi) air pressure or
damage may result to oil cooler.

6. Remove all remaining solvent from the system with
compressed air.
7. Flush the cooling system again with Automatic
Transmission Fluid (ATF).
After the final flush, connect all lines.
Cooler line joint connector torque :
44 N·m (33 lb·ft)
8. Replenish ATF
9. Start engine to test the system for the free flow o
f
fluid. If the flow is restricted, the cooler assembly o
r
lines must be replaced.
Repeated cleaning and flushing may not remove all
debris from the fluid cooler circuit.
Move the select lever through the various ranges and
return to neutral.
Check for fluid level.
If the fluid level is below the specified range, ATF
must be added.
10. Connect negative battery cable.
11. Remove safety stands.
12. Remove wheel blocks.
