Exhaust System - Upshift Shudder/Idle Vibration

1st to 2nd Upshift Shudder, Judder, Vibration at 2K rpm

Got a '03-05 Accord V6 in your shop that shudders or judders when upshifting from 1st to 2nd gear or vibrates when the engine is idling or running at 2,000 rpm? A deformed or damaged exhaust pipe A mounting bracket could be the culprit.

To fix the mounting bracket, do this:





1. Remove the two 8 mm mounting bolts.

2. Inspect the rubber mount for cracks. If the mount is cracked, replace it.

3. Slip the mount over the stud that's welded to exhaust pipe A, and check the clearance between the mount and the engine cradle. If there's a gap, bend the stud upward until the rubber mount fits with no preload in any direction.

4. Reinstall the mounting bolts. Torque the bolts to 22 N.m (16 lb-ft).

5. Test-drive the vehicle to make sure the problem is fixed.
