glass and the rear quarter window glass. Concern may be duplicated with convertible top down, quarter glass down and front door glass up. When the rear glass is raised, it may catch on the front door glass creating a scissor effect over time. The windows need to be aligned to each other and the convertible top, as a glass system.
Issue
Some 2008-2009 Mustang vehicles equipped with front door sub-woofers (Shaker 500 and Shaker 1000) and built before 07/07/2008 may exhibit static, crackle, pop, or distorted sound from the front door sub-woofer.
Issue

On 4.0L engines there may also be an above average engine presence. The wrong transmission crossmember assembly may have been installed from the factory. Similar complaints may also occur if the transmission crossmember and the transmission support insulator were improperly reassembled after transmission removal.
Issue

Some 2009 Mustangs equipped with a 4.0L engine may exhibit a belt squeal or belt
chirp from the front end accessory drive (FEAD) belt near the power steering pulley area.
Issue
Some 2005-2009 Mustangs equipped with a 5R55S automatic transmission may experience shifting concerns. A loss of 2nd, 3rd, and 5th gear may have overdrive band or intermediate band failures due to servo pin case bore wear causing reduced apply pressure.
Issue
Some 2005-2010 Mustang vehicles built before 04/05/2009 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.

Issue
Some 2007-2009 Mustang Shelby GT500s may exhibit the following clutch/transmission symptoms: hard to disengage or engage 1st and reverse, hard to shift all gears, vehicle creeps with transmission in gear and clutch pedal fully depressed without brake pedal application. These symptoms may be caused by the clutch not disengaging fully when the clutch pedal is fully depressed. This may be caused by excessive heat build-up during unique traffic conditions (example: severe stop/go urban driving, excessive clutch slipping). The clutch system is designed for performance driving conditions.
Issue
