WARNING! IMPORTANT NOTICE!
POST INSTALLATION ADJUSTMENT.
Please note: The following
instructions were made to act as a guide/reference, if you
are inexperienced with performing these types of critical adjustments it is
highly
recommended that you contact a certified professional to make the
adjustments for you!
It is imperative that after your new Monster
700R4/4L60/2004R transmission has been installed that the Throttle
Valve (TV) Cable gets adjusted properly, DAMAGE WILL OCCUR to the
transmission, voiding the warranty. If you are unsure about the proper
adjustment needed, call the Monster Transmission tech line for help or refer
to a General Motors service manual for additional information and reference.
►
Function of the TV Cable: Many people believe
that this is a detent downshift cable and that this is the only function
that the cable performs. In actuality, the TV Cable controls line pressures,
shift points, part throttle downshifts and detent downshifts. The cable
functions similarly to the combination vacuum modulator/cable systems found
on other automatic transmissions.
►
TV Cable Connection: If you are retrofitting
your Monster 700R4/4L60/2004R transmission in place of a different
model transmission (i.e. TH-350 or TH-400) it is imperative that you follow
the TV Cable bracket fabrication instructions. If your Monster Transmission
700R4/4L60/2004R is replacing an original 700R4/4L60/2004R then skip to Step 2.
Step 1 Obtain a cable that is designed for use
with the 700R4/4L60/2004R transmission. The TH-350 and older TH-200 cables are
designed differently and will not work. A salvage yard cable may work but be
forewarned: There are about 30 different length cables found on stock
vehicles and a cable that is too short in your application will not work.
Also, used cables could have a number of problems as well, including
stretched cables, damaged sheathing or housings or mutilated cable ends.
Monster Transmission & Performance recommends our universal TV Cable (Model#
K65940U) that is designed to work correctly
in any 700R4/4L60/2004R application.
 Step
2 With the carburetor/throttle body end of the TV Cable disconnected,
pull the link out of the transmission and fit the cable end to the link as
shown in Figure 1. Push the TV Cable sheath into the seal in the
transmission and tighten the 10mm retaining bolt. If your vehicle has a
factory installed bracket for the TV Cable then skip to Step 4.
Step 3 Install a bracket that will allow the TV
Cable to mount to the carburetor/throttle body. Monster Transmission &
Performance carries
two brackets: Model#
AS2-02K works with most
Holly carburetors, or Model#
AS3-03K for Edelbrock
Performer carburetors.
If you are using a Chevrolet TBI/TPI induction system,
then correct brackets can be obtained from a salvage yard or a local car
dealership.
Figure 2 demonstrates the correct geometry for
the TV Cable mounting position. Use the following procedure to determine if
your ADJUSTER MOUNTING POINT is correct.
a. Push in the Adjust Tab and retract the Slider in the direction
shown in Figure 3.
b. Without allowing the Slider to move, pull the cable until it stops
and measure from the mounting bracket to the cable end. Add 3/16" to this
measurement and that will determine the ADJUSTER MOUNTING POINT distance at
full throttle (WOT).
c.
Also note in Figure 2 that the distance from the throttle shaft to
the cable end is referenced. This distance must be between 1 7/64" and 1
1/8"! The cable end mounting point should follow a 78° arc between closed
throttle and WOT in order to achieve the proper amount of pull on the cable.
Step 4 Adjustment of the TV Cable on a gasoline
engine. For a diesel application go to Step 5.
a. Adjustments are made with the engine off. Locate the Adjust Tab on
the cable housing. Press in the tab and push the slider as shown in
Figure 3.
b. Release the tab and rotate the throttle lever to WOT and the cable
will self adjust itself as evidenced by a few audible clicks. Release the
throttle lever and check the cable for any signs of binding or sticking.
 c.
Road test the vehicle. Under moderate acceleration your shift points should
be close to the following:
1-2…………………20 MPH
2-3…………………28-32 MPH
3-4…………………42-45 MPH
If the cable is adjusted too loosely your transmission
will exhibit soft, stacked shifts (not spread out). DO NOT CONTINUE
DRIVING VEHICLE IF THIS HAPPENS! Immediately readjust cable. If you
continue to have problems, please contact the Monster Transmission &
Performance Tech
Department for assistance.
Step 5 Adjustments of the TV Cable on a diesel
engine.
a. Adjustments are made with the engine off. If equipped with cruise
control, remove the control rod.
b. Disconnect the TV Cable end from the throttle lever.
c. Loosen the locknut on the pump rod and shorten several turns.
d. Turn throttle lever to WOT and tighten the pump rod locknut.
e. Lengthen pump rod until injection pump lever contacts the full
throttle stop.
f. Release the throttle lever and tighten the pump rod locknut.
g. Remove pump rod from the throttle lever.
h. Reconnect the TV Cable end to the throttle lever.
i. Press in the Adjust Tab and move Slider as shown in Figure 3.
j. Release the tab and rotate the throttle lever to WOT and the cable
will self adjust itself as evidenced by a few audible clicks. Release the
throttle lever and check the cable for any signs of binding or sticking.
k. Reconnect the pump rod and cruise control throttle rod, if
equipped.
l. If equipped with cruise control, adjust servo throttle rod to
minimum slack.
m. Road test the vehicle. Under moderate acceleration your shift
points should be close to the following:
1-2…………………20 MPH
2-3…………………28-32 MPH
3-4…………………42-45 MPH
n. If the cable is adjusted too loosely your transmission will
exhibit soft, stacked shifts (not spread out). DO NOT CONTINUE DRIVING
VEHICLE IF THIS HAPPENS! Immediately readjust cable. If you continue to
have problems, please contact the Monster Transmission tech department for
assistance. (800)708-0087
