without a sleeve, press only on the race which is ad-
jacent to the mounting surface. If a press is not
available, seat the bearing with a drift and a hammer,
driving against the supported race.
4–7. REMOVING (OR INSTALLING)
TRANSMISSION
a. Drain Transmission Fluid. Drain the trans-
mission fluid from the transmission before removal
from the vehicle. For better drainage, the transmission
should be warm. Because applications will differ, con-
sult the vehicle service manual for specific instructions
for transmission removal and installation.
b. Check Linkages and Lines. Make sure that
all linkage controls, cooler lines, temperature connec-
tion, input and output couplings, transmission fluid
filler tube and other equipment such as attached park-
ing brake handle, etc., and mounting bolts are discon-
nected before transmission removal. Carefully place
hydraulic lines out of the way of damage and cover all
openings to keep out dirt.
NOTE:
Position jack or joint sling to coincide with the
transmission center of gravity.
c. Remove, Clean Transmission. Clean the ex-
terior of the transmission. If steam cleaning is used,
disassemble and dry the transmission immediately be-
cause condensation allowed to remain in the transmis-
sion could cause rust.
d. Transmission Installation
(1) Use a transmission jack to raise the trans-
mission into mounting position. Mount the transmis-
sion.
(2) Make all connections from vehicle to
transmission.
(3) Verify all mechanical and electrical con-
nections.
(4) Fill the transmission with transmission
fluid (Paragraph 3–5 through 3–10) and road test after
installation.
