Loss of Pedal Height/Low Clutch Pedal, Clutch Does not Release Fully Until Full Pedal Travel, Difficulty Changing Gears (Tighten Clutch Pressure Plate Bolts)
| Subject: | Loss of Pedal Height/Low Clutch Pedal, Clutch Doesn't Release Fully Until Full Pedal Travel, Difficulty Changing Gears (Tighten Clutch Pressure Plate Bolts) |
| Models: | 2004 Pontiac GTO Built Prior to VIN Breakpoint 4L234149 |
| with Manual Transmission |
Condition
Some customers may comment on progressive loss of pedal height (which, if not addressed, could result in the clutch not fully releasing until full pedal travel), difficulty in changing gears or a low clutch pedal.
Cause
Root cause analysis has identified that the clutch pressure plate bolt torque on vehicles produced before the above VIN breakpoint may loosen in service. This condition was corrected in production by increasing the torque of the clutch pressure plate bolts. This change became effective in vehicle production beginning with VIN 4L234149, built on 2/11/04.
Correction
Important:
• This correction MUST be performed before retail delivery of new vehicles
built prior to VIN breakpoint 4L234149. • Whenever performing repairs to the clutch assembly on vehicles built both
prior to and after the specified VIN breakpoint, ensure that all six pressure plate
retaining bolts are tightened in sequence as shown in the illustration.
Apply additional torque to the clutch pressure plate-to-flywheel bolts to the revised torque specification of 70 N·m +/-7 N·m (52 lb ft +/-5 lb ft). Follow the tightening sequence shown in the illustration.
SI will be updated with this revised torque specification in the future.
Tighten the bolts in sequence in 4 steps:
- Tighten all bolts to 15 N·m (11 lb ft).
- Tighten all bolts to 35 N·m (26 lb ft).
- Tighten all bolts to 55 N·m (41 lb ft).
- Tighten all bolts to 70 N·m (52 lb ft).
