Linear Solenoids/lnhibitor Solenoid
)Test
1. Disconnect the 8P connector from the solenoid har-
ness connector.
SOLENOID HARNESSCONNECTOR
ATF OIPSTICK
Measure the resistance of the shift control linear
solenoid between the No. 3 and No. 7 terminals of
the solenoid harness connector.
Measure the resistance of the PH-PL control linear
solenoid between the No. 2 and No. 6 terminals
Measure the resistance of the start clutch control
linear solenoid between the No 4 and No. 8 termi-
nats,
STANDARD:38-6.8O
Measure the resistance of the inhibitor solenoid
between the No. 5 terminal and body ground
STANDARD:11.7 - 21.0 O
Replace the lower valve body assembly if any
solenoid resistance is not within its standard.
7. lf all ot the resistances are within the standard, a
clicking sound should be heard when connectrng
the batterv terminals to the solenoid harness con-
nector terminals below:
Shift control linear solsnoid

@ Make sure lifts, iacks, and saf€ty stands
are placsd prop€rly {sea section 1).
CAUTION: While removing and installing th6 lower
valve body asssmbly, b€ sule not to allow dust and
other for€ign particles to entsr inio the transmksion.
1. Raise the front of the vehicle, and support it with
safetv stands (see section 1).
2. Set the parking brake, and block both rear wheels
securetv.

6.
Remove the drain plug, and drain the CVT fluid.
Reinstall the drain plug with a new sealing washer(see page 1+299).
CAUTION: Keop all of other toreign parliclos out of
the transmission.
Disconnect the 8P connector from the solenoid har-
ness connector.
Remove the ATF cooler hoses at the ATF cooler
lines. Turn the ends of the ATF cooler hoses up to
prevent ATF from flowing out, then plug the ATF
cooler noses.
CAUTION: Keep all of other foroign particlo3 out of
tho transmission.
