B&M 70235 TRANSPAK - Manual

9500260-12 Printed in U.S.A.
The B&M TH-700 (4L60) Transpak
has been designed to work on all 1982
thru 1993 TH-700’s (4L60's). This kit
WILL NOT work on 1992 and later
4L60E (electronic) models. During 1982
thru 1993 model years four major
changes were made to the TH-700’s
hydraulic circuitry. It is important that
you know the year model of the trans-
mission your working on so that you
can identify the correct checkball place-
ment diagram. Figure 1 describes
where to look on your transmission for
model year identification. If the original
transmission in your vehicle was re-
placed by a factory rebuild, the I.D.
number may have been changed. In
this case you will have to compare the
components in your transmission with
the check ball placement diagrams in
the instructions to determine the cor-
rect check ball placement.
WARNING: Incorrect checkball
placement can result in serious
transmission damage. Be sure to
follow the instructions carefully.
We have included a section on TV
cable installation that will be helpful to
individuals using the TH-700 with after-
market carburetors, manifolds or in a
custom vehicle installation.
B&M's TH-700 Transpak can be in-
stalled by anyone with minimum me-
chanical experience. It is however, im- portant to closely follow the instruc-
tions.
We recommend that you read
through the instructions completely
before beginning the installation,
so you can familiarize yourself with
the installation procedure and tools
required. Check the tool list at the
end of these instructions for the
tools required to install your B&M
TH-700 Transpak.
NOTE: The B&M TH-700 Transpak is
not a cure-all for an ailing transmis-
sion. If your transmission is slipping or
in poor general shape, the installation
of this Transpak may worsen the con-
dition. However on a properly operating
transmission in average condition, the
Transpak will provide the kind of trans-
mission performance your looking for.
When installing your Transpak there
are several other B&M products you
may wish to consider:
TH-700 R4 KICKDOWN KIT #70237
The TH-700 has a hydraulic circuit that
causes a forced 4-3 down shift when-
ever the throttle is opened past two
thirds travel. In some applications a
part throttle forced 4-3 down shift is
undesirable, after many customer re-
quests B&M has developed an easily
installed kit that will eliminate the part
throttle 4-3 down shift feature. This kit
does not alter normal shift speeds or affect detent (wide open throttle 4-3)
operation. This kit is best installed
along with B&M’s #70235 Transpak.
However it can also be installed inde-
pendent of other modifications, and
valve body removal is not required (pan
gasket not included).
Converter Lockup Control #70244/
70248 Provides electronic control of
the vehicle speed where lockup takes
place on GM transmissions with lockup
converter. Eliminates lock and unlock
cycling and premature unwanted
lockup. Also ideal for lockup operation
in vehicles that did not come with
lockup converter transmissions. Works
with all GM lockup transmissions.
TRANSMISSION OIL COOLER We
feel that it is very important that every
vehicle in addition to the radiator heat
exchanger should have an oil cooler.
Heat is the major cause of transmis-
sion failures, and an oil cooler is an
inexpensive safeguard against over-
heating. B&M offers a wide range of
transmission coolers to suit every need,
which are available at your B&M dealer.
The TH-700 runs hotter than most other
automatic transmissions, making an
oil cooler almost a necessity.

mission fluid is the industry’s leading
