Congratulations! You have just pur-
chased one of the finest cast alumi-
num pans available for the Chrysler
NAG-1 transmissions. This
B&M
Cast Aluminum Deep Oil Pan has
been designed to work on most
Chrysler/Dodge/Jeep
vehicles
equipped with NAG-1 (W5A380 &
W5A580) transmissions. The
B&M
Cast Aluminum Deep Oil Pan pro-
vides several advantages over stock
factory oil pans. The extra capacity
provides increased oil volume and
added cooling, while the aluminum
construction increases case rigidity.
The magnetic drain plug feature al-
lows regular transmission mainte-
nance and oil changes without the
usual mess associated with
“drop-
ping the pan, ” and limits ferrous de-
bris from circulating in the transmis-
sion.
NOTE: The NAG-1 transmissions
do not come with a dip stick. You
will need a B&M NAG-1 Locking
Dipstick P/N 22300, P/N 22301 or
P/N 22302 (check for vehicle ap-
plications) to measure fluid level
or have a shop with a scanner
tool do the installation for you.
When installing your
B&M Cast
Aluminum Deep Oil Pan you may
wish to consider a
B&M Transmis-
sion Temperature Gauge. Most
transmission and converter failures
can be traced directly to excessive
heat. This accurate temperature
gauge comes with a light kit, color-
coded dial face, antiglare enclo-
sure, wires, terminals, special
sending unit, and T-fitting for easy
installation. Available at your
B&M
dealer.
INTRODUCTION
This deep oil pan can be installed
in about an hour by carefully fol-
lowing the instructions. Check the
tool list at the end of these instruc-
tions for the tools required to install
your
B&M Cast Aluminum Deep
Oil Pan. Transmission components
are precision fit and dirt is the
number one enemy of an automat-
ic transmission. Automatic trans-
missions operate at temperatures
between 150°F and 250°F. It is
suggested that the vehicle be al-
lowed to cool off for a few hours to
avoid burns from hot oil and parts.
The vehicle should be off the
ground for ease of installation
–
jack stands, wheel ramps or a hoist
will work fine. MAKE SURE VEHI-
CLE IS FIRMLY SUPPORTED -
DO NOT WORK UNDER A VEHI-
CLE IF IT IS SUPPORTED BY
ONLY A JACK! Try to raise the ve-
hicle 1-2 feet so you will have plenty
of room to work. Also, have a small
box to put bolts in and a drain pan to
catch oil.
NOTE: This kit does not come
with a transmission filter or gas-
ket.
INSTALLATION
STEP 1. Place a drain pan under-
neath transmission. To drain the oil
pan, remove the two bolts and hold
downs at the front of the transmis-
sion using a T30 torx socket, exten-
sion and ratchet.
STEP 2. Loosen the two middle
bolts until fluid starts to drip from the
front of the pan. If the pan and gas-
ket sticks, pry it down slightly with a
screwdriver to break the seal.
NOTE: Don’t damage the trans-
mission surface as leaks could
develop.
STEP 3. Loosen the two rear bolts
by 2 turns and let the pan hang
down so the fluid can drain.
NOTE: On some applications it
might be easier to reach the rear
bolts by using a torx bit and a
wrench.
STEP 4. After the fluid has drained
from the pan, remove the two middle
