7. Remove exhaust center tube and insulator. Refer to EX-2, "EXHAUST SYSTEM" .
8. Remove propeller shaft. Refer to PR-2, "
REAR PROPELLER SHAFT" .
9. Using a transmission jack, support the bottom of the rear final
drive.
10. Remove the mounting nuts on the rear suspension member, and
lower the transmission jack carefully until just before the rear
suspension member is removed from the stud bolts on the vehi-
cle.
11. Disconnect fuel filler hose, EVAP hose and vent hose at fuel
tank side.
12. For disconnection procedure of the quick connector on the
evaporator hose, Refer to FL-4, "
FUEL LEVEL SENSOR UNIT,
FUEL FILTER AND FUEL PUMP ASSEMBLY" .
13. Remove fuel tank protector.
14. Remove fuel tank band mounting bolts while supporting fuel
tank.
15. Remove fuel tank.
INSTALLATION
Install in the reverse order of removal paying attention to the following.
●Surely clamp fuel hoses and insert hose to the length below.
●Be sure hose clamp is not placed on swelled area of fuel tube.
●Tighten fuel hose clamp so that the distance between its lugs becomes to the following.
●Push the mounting band pin to the vehicle side securely.
●Before fixing the fuel tank, temporarily install the filler tube.
CAUTION:
Use genuine fuel filler tube mounting bolts or equivalent. Make sure to tighten them to the speci-
fied torque.
●To connect the quick connector, refer to FL-4, "FUEL LEVEL SENSOR UNIT, FUEL FILTER AND FUEL
PUMP ASSEMBLY" .

CLUTCH AND BAND CHART
●*1: Operates when overdrive control switch is set in “OFF” position.
●*2: Oil pressure is applied to both 2nd “apply” side and 3rd “release” side of band servo piston. However, brake band does not con-
tract because oil pressure area on the “release” side is greater than that on the “apply” side.
●*3: Oil pressure is applied to 4th “apply” side in condition *2 above, and brake band contracts.
●*4: A/T will not shift to 4th when overdrive control switch is set in “OFF” position.
●: Operates.
●A: Operates when throttle opening is less than 3/16, activating engine brake.
●B: Operates during “progressive” acceleration.
●C: Operates but does not affect power transmission.
●D: Operates when throttle opening is less than 3/16, but does not affect engine brake. Shift positionRever

POWER TRANSMISSION
“N” and “P” Positions
●“N” position
Power from the input shaft is not transmitted to the output shaft because the clutches do not operate.
●“P” position
Similar to the “N” position, the clutches do not operate. The parking pawl engages with the parking gear to
mechanically hold the output shaft so that the power train is locked.
