2.
Check adjustment of transmission kickdown linkage (automatic transmission only). Refer to Figures 20 and 21. Adjust kickdown rod as follows.
a.
Attach 6 lb. weight to transmission kickdown lever.
b.
Rotate throttle to wide open position.
c.
Insert a 0.060 +/- .005 inch spacer between throttle lever and adjusting screw on fuel injection pump kickdown lever. If less than .060 inch
clearance, back off adjusting screw.
d.
Rotate adjusting screw until contact is made between screw and the 0.060 inch spacer.
e.
Remove the 0.060 inch spacer.
f.
Check gap after spacer is removed. A gap of 0.010 to 0.070 inch is acceptable.
g.
Remove the 6 lb. weight.
If kickdown linkage is out of adjustment, transmission up-shifting at low engine RPM can result. This would not allow maximum engine RPM and
power. Also, transmission may kickdown too early, or have delayed up-shifts, if misadjusted.
3.
Check adjustment of Vacuum Regulator Valve (VRV) (automatic transmissions only). Refer to Figures 22 and 23. On a 6.9L diesel
engineequipped truck with C6 automatic transmission, a VRV provides a vacuum signal which is proportional to the throttle position, to the
transmission vacuum diaphragm. To check the VRV for proper operation and adjustment, the engine must not be running.
