B&M 10280 CAST DEEP PAN - Manual (Page 2)

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.
INSTALLATION
STEP 1. Drain the oil pan. Some
model Torqueflites have a drain plug.
If yours has one, remove drain plug
and allow the fluid to drain. Other-
wise, loosen and remove the oil pan
bolts one at a time, working towards
the front of the transmission. Re-
move the last two bolts slowly and
the pan will tilt down to allow the last
of the fluid to drain. If the pan sticks
to the old gasket, pry it down slightly
with a screwdriver to break the seal
before removing the last two bolts.
After the last bolt is removed, the pan
can be lowered and set aside.
STEP 2. The oil filter will now be ex-
posed. Remove the three (3) filter
screws with a screwdriver. Remove
and discard the original filter. Scrape
off any old pan gasket material that
may be stuck to the transmission
case. Old gasket material can cause
leaks. NOTE: OEM filter on Diesel
truck applications may be re-
quired.
STEP 3. Install filter extension
adapter (3/8” thick A-518, 1-1/4” thick
A-727), filter extension gasket and fil-
ter onto valve body using the supplied
oil filter screws. NOTE: The gasket
is placed between the filter exten-
sion and valve body. Use the cor-
responding screws according to
adapter length.
STEP 4. Thoroughly clean out the
B&M pan and make sure there are
no chips and/or dirt particles inside.
Install the new pan gasket and deep
pan. NOTE: If a reusable gasket
was removed- clean, inspect, and
re-use unless gasket is damaged.
Use the supplied pan bolts (the two
1-1/4” long bolts are used to attach
the linkage) and washers (torque to
12 lbs-ft). Do not overtighten as this
can cause leaks. Make sure drain plug
is tight.
STEP 5. If using a temperature sen-
sor, install in provided 1/8” NPT port
on driver’s side otherwise tighten 1/8”
NPT plug.

STEP 6. Lower vehicle and add six
quarts of Dexron III or B&M Trick Shift
ATF. NOTE: Check your owner’s
manual as some newer transmis-
sions require MOPAR ATF+4 oil.
STEP 7. Start the engine and place
shifter in the neutral position. Add fluid
until the oil level is at the “add” mark.
Shift the transmission through all gear
positions. Check the oil pan and gas-
kets for leaks. Once the transmission
has warmed up, place shifter in neu-
tral and add fluid to bring the level up
to “full.” Do not overfill as this causes
foaming and overheating.
