Incomplete clutch release and/or hydraulic fluid leaking into the cab from the clutch master cylinder may be caused by the reinforcement plate on the clutch master cylinder separating from the dash panel. The separation of the reinforcement plate reduces the clutch master cylinder pushrod travel. Reinforcement plate separation can also cause deflection of the clutch master cylinder that results in a misalignment of the pushrod to the clutch master cylinder. Misalignment causes the “O” ring in front of the secondary seal to leak hydraulic fluid. ACTION Inspect the truck and, if necessary, use the following service procedure to install a reinforcement kit. INSPECTION PROCEDURE 1. If the truck is a 1988 or later model, confirm that the starter interlock switch operates (the engine can be started) with the clutch pedal at least 0.5″ (12.7 mm) from the floor. 2. Test drive the truck and check for good clutch release. There should be no grinding of the gears, particularly when shifting from neutral to reverse gear. 3. If the truck passes these tests, go to the Small Reinforcement Installation Procedure Section of this article. 4. If either of the above conditions are not met, check the hydraulic system for air. Refer to the Suggested Bleeding Procedure at the end of this article. 5. Test drive the truck and check for improved clutch release. 6. If there is no improvement, proceed as follows: a. Remove the clutch master cylinder pushrod from the release lever pin on the release lever. b. Make sure the hole in the pushrod lines up with the pin, for those units requiring a minimal force

1. Raise and support the vehicle. Using the Hydraulic Line Connector Remover (308-182, T88T-70522-A), disconnect the hydraulic line from the clutch slave cylinder. See Fig. 9 . 2. Lower the vehicle. Remove the 2 screws and the lower steering column finish panel. See Fig. 10 . Remove the 5 bolts and the lower reinforcement panel. See Fig. 11 . 3. Remove the clutch master cylinder reservoir. See Fig. 16 . Remove the 3 push pins, 4 bolts, 4 screws and the inner fender splash shield. 4. Unclip the hydraulic line-to-frame retainer. Twist the clutch master cylinder clockwise 45 degrees to unlock it from the support bracket. See Fig. 17 . Remove the clutch master cylinder reservoir, the slave cylinder hydraulic line and the clutch master cylinder as an assembly. 5. Install a NEW clutch master cylinder push rod bushing. To install, reverse the removal procedure. Rotate the clutch master cylinder 45 degrees counterclockwise. Bleed the clutch hydraulic system. See BLEEDING .

SYMPTOM The vehicle may have one or more of these symptoms: • Idle fluctuates between 500 and 1,500 RPM (The fluctuation is more pronounced before the engine reaches normal operating temperature.) • Shudder or judder when accelerating from a stop or just before stopping • Surging at highway speeds between 2,000 and 3,000 RPM • Excessive shock when the engine is cold and you start to accelerate • A “coo” sound, lasting about 5 to 10 seconds, after coming to a stop PROBABLE CAUSE The problem may have one or more of these causes: • TCM control unit programming is too sensitive. • The start clutch assembly is worn. • The start clutch control valve is contaminated. CORRECTIVE ACTION Replace the start clutch assembly, the start clutch control valve, and the TCM.REPAIR PROCEDURE NOTE: Make sure the work surface and the CVT are completely clean. Use lint-free towels, and use a dedicated, clean solvent tank for cleaning the CVT parts. If you do not keep everything very clean, the repair may not be successful. 1. Soak the new start clutch assembly in Honda ATF-Z1 for at least 30 minutes. NEW START CLUTCH ASSEMBLY 2. Remove the transmission from the vehicle. See page 14-304 of the 1996–00 Civic Service Manual. 3. Cover with clean shop towels all of the openings in the transmission and anything else that might get damaged by water and cleaning chemicals (axle openings, breather, and electrical connectors). Clean all the dirt and grease off of the transmission before you start disassembly.

ignition switch and cruise control main switch to On position. 2. Ensure main switch indicator lamp illuminates. If lamp does not illuminate, check continuity between terminals of cruise control main switch, Fig. 16 through 19 . If switch operates correctly, repair wire harness. 3. Measure voltage at following terminals of the control unit, Fig. 20 through 25 . If terminal voltage are correct, replace cruise control unit. 4. Disconnect cruise stop lamp and clutch switches and ensure continuity exists between terminals only with pedal depressed. 5. If switches operate correctly, repair wiring to switches. 6. Check for continuity between terminals of cruise control switch, Fig. 26 through 29 . If switch operates correctly, repair wire harness.
