GM Hi-Tech Kickdown Kit Installation Instructions
Step 6: The tear drop will be attached to the carburetor throttle arm
by the hex carb fitting. Separate the hex carb fitting from the
kickdown throttle body fitting. Install the hex carb fitting and
the tear drop onto the carburetor throttle arm as shown in Fig.
6. Hook the springs to the tear drop and tighten the nylock
nut on the hex carb fitting. Then back the nylock nut off just
enough that the tear drop can pivot freely.
Step 7: Remove the kickdown cable housing from the transmission.
Re-install the inner wire into the kickdown cable housing.
Step 8: On the trans tube at the transmission end of the kickdown
cable there will be either one or two o-ring grooves. TH350
& TH200 use one o-ring, and the 700-R4, TH200-4R, and
4L60 use two o-rings. Lightly lubricate the kickdown cable
o-ring(s) with clean transmission fluid and slide the o-ring(s)
into the groove(s) on the trans tube. To help prevent leakage
add a small amount of silicone sealant (RTV) around the
trans tube above the top o-ring. Fig. 3
Step 9: Insert the hook on the transmission kickdown rod into the hole
in the cable end. Install the trans tube into the transmission,
and secure with the tube hold down clip and bolt.
Step 10: Before connecting the kickdown cable to the carburetor,
make sure that the throttle linkage is properly adjusted.
Verify at the carburetor that the throttle is wide open while
you have a helper hold the accelerator pedal to the floor.
Once you are sure that the throttle linkage is adjusted
correctly, slide the kickdown throttle body fitting onto the
kickdown cable inner wire, and connect the kickdown throttle
body fitting to the hex carb fitting.
Step 11: This step will also be much easier with a helper. Slide the
kickdown cable end stop onto the inner wire. Move the
throttle to wide open and hold it there while pulling the
kickdown inner wire as tight as possible. Slide the cable
end stop up against the kickdown throttle body fitting and
tighten the set screw using the supplied 5/64" Allen wrench.
Release the throttle. When the kickdown cable is properly
adjusted you should be able to open the throttle to the wide
open position without interference from the kickdown cable;
and with the throttle wide open, you should not have any
slack in the kickdown cable.
Double check to be sure that all carburetor, throttle and
kickdown linkage operates freely without binding, then test
drive. Once the kickdown cable is correctly adjusted and
operating properly you can cut off the excess inner wire,
leaving about 1/2" extending beyond the cable end stop
to allow for future adjustment if needed. Final installation
should look like Fig. 6 and Fig. 7.
