INSPECTION AND CHANGE
1) Before changing or inspecting oil, be sure to stop engine and lift
vehicle horizontally.
2) With vehicle lifted up, check oil level and leakage. If leakage ex-
ists, correct or repair it.
3) Drain old oil and fill new specified oil as shown below by speci-
fied amount (roughly up to level hole).
NOTE:

It is highly recommended to use SAE 75W-90 gear oil.

Whenever vehicle is hoisted for any other service work
than oil change, also be sure to check for oil leakage and
status of breather hoses.

If water or rust is mixed in drained oil, be sure to check
breather hose and boot of transmission and transfer.

12) Remove engine to transmission nuts.
13) Disconnect connectors from VSS, output speed sensor, input
speed sensor, TR switch, shift & TCC solenoid valves and oth-
er electrical parts, and release their wire harness from clamps.
14) Apply transmission jack and take off rear mounting member by
removing its bolts.
15) With transmission (and transfer if equipped) assembly held up
on jack, move them to the rear and lower them including torque
converter.
WARNING:
Transmission (and transfer if equipped) assembly may
tilt rearward on jack. It is recommended to use an auxil-
iary arm of jack for the purpose of safety.
AFTER DISMOUNTING
WARNING:
Be sure to keep transmission (and transfer if equipped) as-
sembly horizontal throughout the work. Should they be
tilted, torque converter may fall off and cause personal inju-
ry and A / T fluid may flow out.
1) Remove breather hoses.
2) Remove transfer by removing its bolts, if equipped.
