NAG-1 Cast Aluminum
Deep Oil Pan
(see www.bmracing.com for the latest vehicle fitment applications and model years)
Part Number 10300

Congratulations! You have just purchased one of the finest cast aluminum 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 provides 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 allows regular transmission maintenance and oil changes without the
usual mess associated with “dropping the pan,” and limits ferrous debris from circulating in the transmission.
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 applications) 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, colorcoded dial face, antiglare enclosure, 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 following the instructions. Check the
tool list at the end of these instructions 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 automatic transmission. Automatic transmissions operate at temperatures
between 150°F and 250°F. It is
suggested that the vehicle be allowed 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 VEHICLE IS FIRMLY SUPPORTED DO NOT WORK UNDER A VEHICLE IF IT IS SUPPORTED BY
ONLY A JACK! Try to raise the vehicle 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 gasket.
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 transmission using a T30 torx socket, extension and ratchet.
STEP 2. Loosen the two middle
bolts until fluid starts to drip from the
front of the pan. If the pan and gasket sticks, pry it down slightly with a
screwdriver to break the seal.
NOTE: Don’t damage the transmission 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

bolts and hold downs while supporting the oil pan. Remove the last two
bolts and hold downs slowly while
tilting down the pan to allow the last
of the fluid to drain. After the last
bolts are removed, the pan and gasket can be lowered and set aside.
STEP 5. Remove the magnet from
the pan, fully clean it and set it
aside.
STEP 6. The oil filter will now be
exposed. Pull the filter out of the
valve body, being careful not to
bend the filter pickup tube as it is
plastic and may crack or break. If
the seal remains in the valve body
and does not come out with the filter, remove it by using a flat head
screwdriver. Be careful not to damage the surface.
STEP 7. Install the supplied o-ring
on the extension tube provided in
the kit (See Figure 1). B&M recommends that the transmission filter
be changed at this time. Lubricate
the seal on the transmission filter
(MOPAR p/n: 52108325AA) and the
o-ring with new transmission fluid.
Place the extension tube on the
transmission filter (See Figure 2).
STEP 8. Install the filter assembly
into the valve body (See Figure 3).
STEP 9. Make sure the flat end of
the filter is parallel to the back of the
transmission (See Figure 4).
STEP 10. Stick the magnet removed
earlier on the bottom of the transmission filter as shown (See Figure
5).
STEP 11. Install the reusable gasket
(MOPAR p/n: 52108332AA) onto the
B&M Cast Aluminum Deep Oil
Pan.
STEP 12. Clean the transmission
mating surface with a clean rag.
STEP 13. Install the B&M Cast
Aluminum Deep Oil Pan by using
the supplied hold downs with the
original six bolts removed earlier
and torque the bolts to 8 N-m (70
in.lbs.). Do not over tighten as this
can cause leaks or damage to the
transmission case or gasket.
STEP 14. Using a 3/4” socket &
ratchet, install and tighten the supplied drain plug and gasket.
STEP 15. If using a temperature
sensor, install in provided 1/8” NPT
port on side of pan. Otherwise install
