At Transmission
ADJUST1. On vehicles without Idle Speed Control (ISC), proceed as follows:
a. Check and adjust curb idle speed to specifications with and without throttle solenoid positioner (anti-dieseling solenoid energized, if equipped).
b. Shut off engine and remove air cleaner.
c. De-cam fast idle cam on so that throttle lever is against idle stop or throttle solenoid positioner stop.
2. Place shift lever in Neutral and apply parking brake.
3. Set linkage lever adjustment screw at approximately mid-range.
4. If a new TV control rod assembly is being installed, connect rod to linkage lever at throttle body.
5. Raise and support vehicle.
6. Loosen bolt on sliding trunnion block on TV control rod assembly, removing any corrosion from control rod and freeing up trunnion block so that it slides freely on control rod.
7. Push up on lower end of control rod to ensure linkage lever on throttle body is firmly against throttle lever, then release force on rod and ensure rod stays up.
8. Push TV control lever on transmission up against its internal stop with a force of approximately five lbs and tighten bolt on trunnion block.
NOTE: Do not relax force on lever until bolt is tightened.
9. Lower vehicle and ensure throttle lever is still against stop and if not, repeat steps 2 through 9.
