B&M 70260 CAST DEEP PAN - Manual

Congratulations! You have just pur-
chased one of the finest cast alumi-
num pans available for the General
Motors TH-700 R4, 4L60, 4L60E &
4L65E Transmissions. This B&M Cast
Aluminum Deep Oil Pan has been
designed to work on most Chevrolet/
GMC vehicles equipped with the TH-
700 R4, 4L60, 4L60E & 4L65E trans-
missions. The B&M Cast Aluminum
Deep Oil Pan provides several advan-
tages 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 “drop-
ping the pan,” and limits ferrous de-
bris from circulating in the transmis-
sion.
This B&M Cast Aluminum Deep Oil
Pan can be installed by anyone with
minimal mechanical experience. It is
however, important to closely follow the
instructions.
We recommend that you read through
the instructions completely before be-
ginning the installation, so you can fa-
miliarize yourself with the installation
procedure. Check the tool list at the
end of these instructions for the tools
required to install your Deep Oil Pan.
When installing your Deep Oil Pan
there are several other B&M products
you may wish to consider: TRANSMISSION OIL COOLER: We
feel that it is very important that every
vehicle should have a transmission oil
cooler in addition to the radiator heat
exchanger. Heat is the major cause
of transmission failures, and an oil
cooler is an inexpensive safeguard
against overheating. B&M offers a
wide range of transmission coolers to
suit every need, which are available
at your B&M dealer.
TRICK SHIFT PERFORMANCE ATF:
Trick Shift performance automatic
transmission fluid is the industry’s
leading performance ATF. A specially
blended oil with foam inhibitors, ex-
treme pressure agents and shift im-
provers, this fluid assures protection
while delivering the fastest possible
shifts. You literally “Pour in perfor-
mance.” Available at your B&M dealer.
INTRODUCTION
This Deep Oil Pan can be installed in
about an hour by carefully following
the instructions. Transmission com-
ponents are precision fit and dirt is the
number one enemy of an automatic
transmission. Cleanliness is very im-
portant, so a clean work surface from
which oil can easily be removed is
necessary.
Caution: Automatic transmissions op-
erate 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.
INSTALLATION
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 al-
low 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. Pull the filter out of the oil
pump, being careful not to bend the
filter pickup tube as it is plastic and
may crack or break. The seal should
remain in the pump - if it comes out
with the filter, remove it from the filter
and carefully reinsert it back into the
pump. Clean the old gasket off of the
case.
STEP 3. The filter must be held in
