It means you don't have a chart to tell you how much ft. lbs to put on each of the adjusting screws.
Make sure you have a good and small torque wrench and don't tighten the bands any tighter, or looser than this.
Intermediate band is the front one with adjusting nut on the drivers side.
Low reverse band is the rear most one with the adjusting nut on the passenger side.
1: remove and discard locknut and install a new one (more than just a good idea.)
2: torque adjusting screw to 10ftlbs. (thats the one inside the nut, not the nut itself)
3: Back off adjusting screw exactly
a. 1 1/2 turns on 1964 C4
b. 1 3/4 turns on 1965-1981 C4
4: Hold adjusting screw from turning and tighten locknut
LOW REVERSE BAND
1: loosen lock nut several turns
2: torque adjusting screw to 10ftlbs
3: Back off adjusting screw 3 full turns
4: hold adjusting screw from turning and tighten lock nut
10 ftlbs isnt very much so you will need a very small ftlb torque wrench. If you can find one that has both inch lbs and ftlbs on it, that would be the one to use.
