DISASSEMBLY
Automatic transmissions nor-
mally operate at temperatures be-
tween 150 F and 250 F. We recom-
mend that the vehicle be allowed to
cool for several hours before at-
tempting disassembly to avoid seri-
ous burns from hot oil and parts.
The vehicle should be raised so
there is at least 2 feet ground clear-
ance for ease of installation and
safety.
MAKE SURE THE VEHICLE IS
RIGIDLY AND SECURELY SUP-
PORTED, JACK STANDS, WHEEL
RAMPS OR A HOIST WORK BEST,
DO NOT USE JACKS ALONE.
Have an oil drain pan ready to catch
oil and a clean tray on which to put small
parts so they won’t get lost or dirty.
STEP 1. Since the AOD is not factory
equipped with an oil pan drain plug
use the following technique to drain
the transmission fluid. Position your
drain pan beneath the transmission to
catch the oil. Remove all but the two
(2) front bolts from the oil pan. Next
loosen but do not remove the two
front center bolts allowing the rear of
the pan to drop down. If the pan sticks
to the gasket, insert a flat screwdriver
between the pan and case and pry
down gently to break pan loose. Now
slowly back the bolts out to permit
draining the remaining oil. Remove
all old pan gasket material from the
pan and case.
STEP 2. Remove three (3) screws
holding the oil filter then pull the filter
straight down from the valve body.
