3. Install the trans cable bracket and the cable housing onto the transmission as
shown in Fig. 4 for C4 and Fig. 5 for C6. C4 uses an existing transmission bolt. The
C6 kit includes a 5/16"-18 x 1" button head bolt and locknut for the trans cable
bracket. NOTE: On the C6 transmission, the cable mounting bracket goes
underneath the casting lug on the side of the transmission.
4. If the throttle cable has already been installed, disconnect the throttle cable from
the throttle arm. If the engine already has a Proflow Cable Bracket (not included)
installed, remove the throttle cable adjuster. Leave the Cable Bracket in place. If
the engine does not have a Proflow PFETCS6055 Cable Bracket already installed,
install one now, following the installation instructions that were provided with
Cable Bracket.
5. The kickdown mounting bracket mounts onto the back side of the Proflow Cable
Bracket. The throttle cable adjuster will pass through the top hole in both the new
kickdown mounting bracket AND the Cable Bracket. Position the kickdown
mounting bracket behind the Cable Bracket so that the 5/16" diameter holes at the
top of both brackets are aligned, the small 3/16" diameter holes near the center of
the two brackets are aligned, and the kickdown cable adjuster is offset towards the
left side of the vehicle.
Attach the kickdown mounting bracket to the Cable Bracket using the supplied #8-
32 x 1/2" button head bolt and nylock nut through the small 3/16" diameter center
holes in both brackets, but do not tighten yet. Insert the throttle cable adjuster (with
the rear nut still installed) from the rear through the top holes in both brackets.
Position it so that the threaded part of the throttle cable adjuster is approximately
