ON-VEHICLE REPAIR
1. REMOVE ENGINE NO.2 UNDER COVER
2. DRAIN ATF
3. REMOVE OIL PAN
NOTICE:
Some fluid will remain in the oil pan.
(a) Remove the 20 bolts.
(b) Remove the oil pan gasket.
4. EXAMINE PARTICLES IN PAN
Remove the magnets and use them to collect steel particles.
Carefully look at the foreign matter and particles in the pan and
on the magnets to anticipate the type of wear you will find in the
transmission.
Steel (magnetic)...bearing, gear and clutch plate wear
Brass (non-magnetic)...bushing wear
5. REMOVE OIL STRAINER
Remove the 4 bolts, the oil strainer and the O-ring.
NOTICE:
Be careful as some fluid will come out with the oil strainer.
6. DISCONNECT TEMPERATURE SENSOR
(a) Disconnect the 7 solenoid connectors.
(b) Remove 2 bolts and the 2 temperature sensors clamp
from the valve body.
(c) Disconnect the 2 temperature sensor from the valve body.
7. DISCONNECT 7 CONNECTORS FROM SHIFT SOLE-

Pattern Select Switch Circuit (2nd Start Switch)
CIRCUIT DESCRIPTION
When 2nd start mode is selected with the pattern select switch, the ECM controls the solenoid valves and
the transmission starts from 2nd gear.
In D position, the transmission automatically shifts up through 3rd to 5th as usual.
In 2nd position, the transmission is held in 2nd gear.
