14. Tighten each capscrew with a click-type torque
wrench 5 lbf·ft (7 N·m). Use the torque pattern
shown in Fig. 9 to distribute the torque evenly.
Repeat this procedure and torque the capscrews
with a click-type torque wrench 15 to 20 lbf·ft (20
to 27 N·m).
15. Install the oil filler tube on the oil pan. Tighten
the tube fitting 90 to 100 lbf·ft (122 to 136 N·m),
then install the drain plug and gasket. Tighten
the drain plug 15 to 20 lbf·ft (20 to 27 N·m).
16. Pour approximately 15 quarts (14 liters) of
Dexron
®
IIE transmission fluid into the transmis-
sion. Start the engine and allow the transmission
fluid to circulate. With the transmission in NEU-
TRAL, check the fluid level. Check for fluid leaks.
Correct any leak with the engine OFF.
Checking the Fluid Level
CAUTION
Operating a transmission with the fluid level
higher or lower than recommended can result in
transmission damage. Do not overfill the transmis-
sion.
Do not mix types and brands of fluid, because of
possible incompatibility. Do not use fluid addi-
tives, friction modifiers, extreme-pressure gear
fluids, or multi-viscosity lubricants.
Cold Check
Clean all dirt away from around the end of the fluid
fill tube before removing the dipstick.
CAUTION
Do not allow foreign matter to enter the transmis-
sion. Dirt or foreign matter in the hydraulic system
may cause undue wear of transmission parts,
make valves stick, and clog passages.
It is important to check the fluid level cold to deter-
mine if the transmission has a sufficient amount of
fluid to be safely operated until a hot check can be
performed.
1. Park the vehicle on a flat, level surface.
2. Apply the parking brakes and chock the rear
tires.
3. Run the engine for at least one minute.
4. Shift from DRIVE to NEUTRAL, and then shift to
REVERSE to fill the hydraulic system.
5. Shift to NEUTRAL and allow the engine to idle at
500–800 rpm.
6. With the engine running at idle, remove the dip-
stick from the tube and wipe clean.
