The oil filter will now be exposed .
Two types are common:
'65-'67 - This filter is a long box-like unit which runs along
the driver's side of the case (See Fig.2). Remove it by
grasping both ends of the box and pulling straight down
carefully, watching out for oil splatter. Remove the O-
ring from the hole in the transmission case if it did not
come out with the oil pick-up tube and discard it.
B&M Deep Oil pans provide several advantages over the
stock factory oil pan.
The extra capacity ensures a large volume of oil for the
transmission oil pump preventing oil pick-up starvation and
added cooling.
The added feature of a drain plug allows regular transmis-
sion maintenance and oil changes without the usual mess of
removing the oil pan. Also, an 1/8" NPT port has been added
to allow for the addition of an automatic transmission tempera-
ture sensor.
Aluminum oil pans have the added feature of additional
cooling from inner and outer fins and provide improved case
rigidity.
Before beginning, check the tools and parts list to make
sure you have all the necessary parts and tools.
This kit can be installed in a few hours by carefully following
directions. Read all instructions first to familiarize yourself with
the parts and procedures. Work slowly and do not force any
parts.
Automatic transmissions operate at temperatures between
150 o F and 250 o F. It is suggested that the vehicle be allowed to
cool 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!! Try to raise it 1 - 2 feet so you
have plenty of room to work easily. Also have a small box or
pan handy to put bolts in so they won’t be lost and a drain pan
to catch oil.
STEP 1.
Drain oil pan. Loosen and remove oil pan bolts one
at a time, working toward the front of the transmission. (Note:
some vehicles will require removal of the crossmember to
remove the pan. Make sure you support the back of the
transmission so you won’t damage the distributor). 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 removing the last two
bolts, to break the seal. After the last bolt is removed, the pan
