Oil-Canning or Exhaust Rattle/Buzz around 2000-2500 RPM – 2005-2010 Ford Mustang

4.6L MANUAL TRANSMISSION – SEPARATOR PLATE BUZZ – BUILT BEFORE 4/5/2009

 

FORD:

2005-2010 Mustang

 

2005-2010 Mustang vehicles built before 4/5/2009 and equipped with a 4.6L engine and manual transmission, may exhibit an oil-canning or exhaust rattle/buzz around 2000 – 2500 RPM during the first few minutes of driving after a cold start.

The sound goes away after the car warms up.

 

The concern may be caused by the separator plate, between the rear face of the engine block and the transmission housing, vibrating and/or contacting the flywheel.

 

SERVICE PROCEDURE

1. Remove transmission.
2. Pry separator plate from the rear face of the block alignment dowels and slide it out from between block and flywheel. Replace with new service part.
3. Install transmission.

NOTE: INSTALL NEW SEPARATOR PLATE TO TRANSMISSION BOLTS IF MISSING OR DAMAGED. (FIGURE 1)
