B&M 70289 CHROME DEEP PAN - Manual

B&M Deep Oil Pans provide several
advantages over the stock factory oil
pan. The extra capacity provides in-
creased oil volume and added cooling
and insures a large volume of oil for the
transmission oil pump, preventing oil
pickup starvation.
The drain plug feature allows regular
transmission maintenance and oil
changes without the usual mess of
draining the oil pan.
The steel oil pan provides these fea-
tures with a minimum of weight in-
crease in a chrome plated eye appeal-
ing package. This kit can be installed
in a short time by anyone with a mini-
mum of mechanical experience. You
will need the following tools:
Drain pan
Gasket scraper
13mm socket
3/8 drive ratchet wrench
2" extension
3/4" wrench
Automatic transmissions operate at
temperatures between 150 O and 250 O 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 that the vehicle is firmly sup-
ported. Do not work under the ve-
hicle if is supported only by a jack.
Try to raise the vehicle 1-2 feet so that
you have plenty of room to work easily.
Also have a small box or pan handy to
put bolyts in so they won't be lost, and
a drain pan to catch oil.
STEP 1. Drain the oil pan. Loosen and
remove the oil pan bolts one at a time,
working towards the front of the trans-
mission. Remove 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 before re-
moving the last two bolts to break the
seal. After the last bolt is removed the
pan can be lowered and set aside.
STEP 2. The oil filter will now be ex-
posed. Pull the pickup tube out of the oil
pump. If the pickup tube o-ring does not
come out with the tube, remove it from
the oil pump. Do not bend the pickup tube as it is plastic and may crack or
break. Inspect your oil filter. If has
varnish on it, or if the transmission has
more than 20,000 miles on it, we rec-
ommend filter replacement.
STEP 3. The stock filter is supported
by a small spring located at the ap-
proximate center of the valve body. See
Figure 1. This spring must be replaced
with the longer spring supplied with the
oil pan. Remove the bolt shown in
Figure 1, take off the spring, install the
B&M spring and the bolt. Tighten the
bolt to 100 in.-lbs. Do not overtighten.
STEP 4. Install the supplied o-rings
on the extension tube supplied with the
pan. See Figure 2. This pan should be
installed with a new filter. It is recom-
mended to use the TH-700R4 filter with
the pre-installed multi-lip seal to pre-
vent air leaks. Lubricate the seal on the
filter and the o-rings with transmission
fluid. Place the extension tube on the
new oil filter. Install the assembly into
the oil pump bore.
STEP 5. Scrape the old gasket off of
the surface of the case. Old gasket
material can cause leaks. Install the
