TOYOTA PREVIA 91-97 REPAIR MANUAL

(Tam Dominh) #1
GENERAL INFORMATION AND MAINTENANCE 1-61


  1. Install any components such as the oil tubes.

  2. Install the new sealant onto the oil pan. Position the magnets so that
    they will not interfere with the oil tubes.

  3. Raise the pan and gasket into position on the transmission and
    install the retaining bolts. Tighten the retaining bolts in a crisscross pattern
    to:



  • A340E and A340F—65 inch Ibs. (7 Nm)

  • A46DE and A46DF—39 inch Ibs. (4 Nm)



  1. Install and tighten the drain plug to 15 ft. Ibs. (20 Nm).

  2. Fluid is added only through the dipstick tube. Use only the proper
    automatic transmission fluid; do not overfill.

  3. Replace the dipstick after filling. Start the engine and allow it to idle.
    DO NOT race the engine!

  4. After the engine has idled for a few minutes, shift the transmission
    slowly through the gears and then return it to P. With the engine still idling,
    check the fluid level on the dipstick. If necessary, add more fluid to raise
    the level to where it is supposed to be.


Transfer Case

FLUID RECOMMENDATIONS

All Previa van transfer cases use Grade GL-4 or GL-5 with the viscosity
ofSAE75W-90gearoil.


LEVEL CHECK


I See Figures 184,185 and 186


The oil in the transfer case should be checked at least every 15,000
miles (24,000 km) and replaced every 25,000-30,000 miles
(40,000-48,000 km), even more frequently if driven in deep water.



  1. With the van parked on a level surface, remove the filler plug from
    the transfer case housing, the filler plug is the higher of the two plugs on
    the unit.

  2. If the lubricant begins to trickle out of the hole, there is enough. Oth-
    erwise, carefully insert your finger (watch out for sharp threads!) and check
    to see if the oil is up to the edge of the hole.

  3. If not, add oil through the hole until the level is at the edge of the

hole. Most gear lubricants come in a plastic squeeze bottle with a nozzle;
making additions simple.


  1. Replace the filler plug and tighten it to 29 ft. Ibs. (39 Nm). Run the
    engine and check for leaks.


DRAIN & REFILL

» See Figures 187 thru 192

Once every 30,000 miles (48,000 km), the oil in the transfer case should
be changed.


  1. The transfer case oil should be hot before it is drained. If the engine
    is at normal operating temperature, the oil should be hot enough.

  2. Raise the van and support it properly on jackstands so that you can
    safely work underneath. You will probably not have enough room to work if
    the van is not raised.

  3. Remove the filler plug from the side of the case. There will be a gas-
    ket underneath this plug. Replace it if damaged.
